Is Gigabit Ethernet right for me?
The question being posed is not specific to a person in general, rather it is a question being asked more often by IT professionals in regards to their company’s network infrastructure.
With the rise in bandwidth-hungry applications, video conferencing, IP telephony, and desktop/server virtualization, the demand on data transmission is ever increasing, with no end in sight. Taking all the requirements into account and future networking growth projections, it is hard to consider keeping a productive company network without taking advantage of Gigabit Ethernet technology.
There are a number of factors to consider when making the decision to incorporate Gigabit Ethernet into the network mix. The questions frequently asked by network managers are:
1) What is the cost to convert to Gigabit Ethernet?
2) Can Gigabit Ethernet technology be incorporated into my existing network?
3) How scalable is Gigabit Ethernet? Will it support future growth?
4) What type of return on investment can be expected?
What is the cost to convert to Gigabit Ethernet?
The main question asked for any type of network build out is, “How much will it cost?”. The answer for implementing Gigabit Ethernet technology into a network environment will vary across organizations and industries. As with any cost allocation process for organizations, an in-depth analysis will have to be performed based on the size of the organization, application usage, type of software, technology used, existing networking equipment, and cabling requirements, just to mention a few.
The main consideration is that the cost associated with either a new network build-out or refresh of existing technology does not vary much for Gigabit Ethernet over the traditional 10/100BASE-T networks. As you will see below, each of the follow questions must be asked and will directly relate to this first question regarding Gigabit Ethernet costs.
Can Gigabit Ethernet technology be incorporated into my existing network?
There are a couple of areas to investigate with regards to the existing network environment to adequately answer this question. First, how old is the existing routing/switching equipment in place, and will it support Gigabit Ethernet transmission? Second, will the existing cabling support the Gigabit transmission transfer rate?
Regarding the routing/switching equipment, at minimum, a Layer 2 Gigabit switch will need to be installed. The existing server could be upgraded to ‘high performance’ levels by replacing the existing 10/100Mbps adapters with Gigabit adapters.
As long as there is CAT-5 cabling in place, which currently supports Fast Ethernet speeds of 100Mbps, then there should not be a need to update the cabling. If new cable is required, keep in mind that enhanced Cat-5 (Cat-5e) should be considered to gain additional signal margin.
How scalable is Gigabit Ethernet?
Unless you are operating a major engineering company in which you are sending 10GB schematic diagrams via email every few minutes, while on a video conference with the entire engineering team who are all connected via their IP phones at their desk and pc video camera, opening the 10GB diagrams within the same LAN, should you expect to hit the cap on a Gigabit Ethernet network.
Once in place, a Gigabit Ethernet environment should support most all applications and the user load for an enterprise level company for years to come. This will allow for years of scalability to add additional users, implement desktop/server virtualization, run video conferencing, etc, to meet the company’s needs and operate in an efficient and effective manner.
What type of return on investment can be expected?
The ROI for converting to a Gigabit Ethernet solution can be best be explained by the increased productivity, due to removing the bottlenecks in bandwidth which slow down the processing of transactions required for applications which end users rely upon to complete their jobs.
By looking at the existing network environment and baselining the actual performance of applications across the network, an IT manager can get a picture of where they are today. The improvement in application performance across the network will be measurable against the established baseline, with the expectation for the end-user to complete their tasks in a much more timely and efficient manner. This will free up resources to be applied elsewhere across the organization and engaged with performing other duties as needed.
Of course, if after an extensive evaluation of the network, it is determined that everything is running at optimal speeds with no latency or issue experienced whatsoever, then there may not be a need to upgrade to Gigabit Ethernet immediately.
At least it will be there to meet the future needs, should your network require it.
What is Gigabit Ethernet
This is a question being asked more frequently, now that the demand for bandwidth is continuing to grow in order to keep up with technological requirements of companies today. To define Gigabit Ethernet in one sentence, “Gigabit Ethernet is a LAN technology, which supports data transfer at the speed (or rate) of one Gigabit per second.” While the word Gigabit may be new to you and not yet appear to be related to speed, nothing could be closer from the truth. Gigabit Ethernet equates to the transfer of date at 1000 Megabits per second or 1,000,000,000 bits per second. Pretty fast huh?
Two commonly used acronyms to identify Gigabit Ethernet are GbE or 1GigE.
What are benefits of Gigabit Ethernet?
The primary benefit for converting over to gigabit Ethernet is for the increase in bandwidth for the running of applications and peripherials. This gigabit transfer speed will allow for much improved performance and will help to eliminate bottle-necks that may have previously been experienced in a Fast Ethernet environment. In order to stay in the game competitively, many companies utilize web conferencing and video conferencing, not to mention the support of a fully functional IP Telephony system which runs over their LAN environment, to support their daily operations.
Gigabit Ethernet also allows a company to keep up with bandwidth hungry applications with a relatively low cost of ownership. In other words, the costs associated with implementing a gigabit Ethernet network is far outweighed by the immediate increase in speed and scalability for future growth. I go into more detail in the article “Is Gigabit Ethernet Right For Me?”
QoS, also known as “Quality of Service” is a feature supported by Gigabit Ethernet. QoS is important for helping to avoid latency issues which will cause distortion in voice transmissions over a telephony system or with video transmission. This is very important when both technologies are competing with data transmittal over the same network.
The History of Gigabit Ethernet
The initial inception of Gigbit Ethernet came about in 1998 when the IEEE adopted the standard known as 802.3z. As the technology was in it’s infancy, the thought was that fiber optic transmission would be the only means of reaching the gigabit speed over an Ethernet technology. Only a short year later, in 1999, Gigabit Ethernet utilizing copper cabling was introduced. This technology, also known as 1000BASE-T, allowed for the gigabit speeds to be transmitted over CAT-5 cabling. This brought about a growing interest in the technology by IT departments, as their existing twisted-pair copper cabling investment could be utilized to run a Gigabit Ethenet network.
As over a decade has now passed, Gigabit Ethernet is an integral part of the discussion for IT departments around the globe, as they speak of their networking requirements for planning purposes. And it does not stop there. There is a 10 Gigabit Ethernet standard, which also exists. This technology, for the most part, has been used as a WAN technology, but is now being seen more and more in a LAN environment. Who knows what is coming down the road. There is much speculation that we will see Terabit Ethernet (TbE) by the year 2015 and possibly 100 Terabit Ethernet a few years after that. For now, Gigabit Ethernet should suffice, one would believe.
Power over Ethernet (PoE)
Power over Ethernet (also abbreviated as PoE) is a technology described as a system to pass electrical power over Ethernet cabling in a safe manner, along with transmitting data as well. The standard set forth by the IEEE for PoE does require that Category 5 (Cat 5) Ethernet cable or higher is used with high power levels. It can operate with a Category 3 (Cat 3) Ethernet cable but only with devices requiring lower power levels. (Category 3 ‘Cat 3’ cabling is rarely used anymore, and not recommended.) The power is supplied in common-mode signaling and transmitted over two or more of the differential pairs of wires found in the Ethernet cable. The power is provided from a power supply within a PoE enabled networking device. This device can be an Ethernet switch, Router or the power can be injected into a cable run with a midspan power supply.
Power over Ethernet (PoE) Uses
The advantage of Power over Ethernet (PoE) technology, is that both data transmittal and power supply are provided in one Ethernet cable. This minimizes wiring requirements in situations where power is not so accessible. A common use for Power over Etherner (PoE) is with Wireless Access Points (AP) distributed throughout a facility. Many time, there is no power outlet located near the AP equipment. Therefore, PoE is a very good solution for providing the required power to this device. Other examples where PoE is useful, would be for IP telephones, video security cameras and even remote Ethernet switches. (A comprehensive list of PoE devices is below) The standard PoE technology can provide 15 W of power over distances of 100 meters or 330 feet. The most recent standard PoE+ is able to provide up to 25 W of power to equipment if the need arises.
Current devices with PoE capibilities
- IP Security Cameras
- Network Routers
- Network Switch
- Intercom / Paging / Public address systems and hallway speaker amplifiers
- VoIP phones
- Wall clocks in rooms and hallways, using Network Time Protocol
- Wireless access points
- Outdoor roof mounted Wireless radios with integrated antennas, 802.11 or 802.16
- Industrial devices (sensors, controllers, meters etc.)
- Access control and Help-points (intercoms, entry cards, keyless entry, etc.)
- Lighting controllers
- Remote Point of Sale (POS) kiosks
- Physical Security devices and controllers
Competing Technologies with Power over Ethernet (PoE)
There are competing technologies that have been around for some time and could be replaced by a PoE technology.
Universal Serial Bus, also known as “USB” can provide both data and power much like PoE. The main disadvantage for USB is that it is designed for shorter cables with a maximum length of 5 meters or 16 feet. Also only 2.5 W of non-isolated power is provided over the USB technology. The common uses for USB currently are for a computer mouse, headset, microphone or a serial port. Since most peripheral equipment , including speakers, scanners, and/or printers, need more power than USB can provide, an alternate power source is normally required. PoE may be an option if the device is PoE compliant.
Firewire is a technology similar to USB and is a serial bus interface standard for high-speed communications and isochronous real-time data transfer. The advantage for firewire is that is can provide substantially more power (up to 45 W), but the disadvantage is the limitation on cable length at 4.5 meters.
When data rate and power requirements are both low for the devices involved, the above to option may be a better solution than PoE. Some other competing technologies include Cellular phones, which use batteries for power and wireless for data connectivity. Remote weather sensors uses very low data rates, so batteries and custom wireless data links are used. Replacing batteries is a nuisance, but if the batteries last six months to a year, the practice may be tolerable. Solar power may be supplemented in some instances, to increase batter life.
Depending on the application and your network requirements, some of the advantages to be considered with using PoE over other technologies are: Inexpensive cabling, Modest power, Fast data rate, Peer-to-peer network access and Network device accessibility by many users. Keep in mind that PoE is becoming more and more popular as more devices today are designed to be PoE compliant.
The Ethernet pinout is composed of the RJ45 and the composition of the Ethernet cable wires. These wires are different which the manufacturers put different range of colors to handpick them. I am going to show you how to wire them correctly to ensure that your connectivity is not tampered with.
Instructions on wiring your Ethernet pinout
This process needs patience and vigilance because one single mistake will result you in repeating it all over again. Ethernet Pinout wiring needs you to follow the set instructions with much care so that you can get to enjoy much benefits that come with it.
Things you need to wire your Ethernet pinout
Here are some of the things you require to undergo the process:
1. Ethernet cable- makes sure you are well known with the categories of present cables. Your connectivity needs will be very important in determining which cable to pick. They range from category 5, 5e or 6, 6a
2. Wire cutters-This tool is important in cutting and striping the present cable. This tool is important in ensuring you do not impose damage on the set cable.
3. Wire stripper to be used on the individual wires.
4. Cable tester to test the present Ethernet cable if it has the connectivity capability.
5. RJ45 clippers to finish up the Ethernet pinout.
Steps on wiring your Ethernet pinout
* Make use of the wire cutter to pull the cable off the reel to a length you desire. Take time to measure the distance where you’ll fit the cables to prevent the Ethernet pinout from unplugging due to the stiffness of the cable.
* Take your wire stripper and remove the cable jacket off at one end. Ensure you implement much care because a single cut of the wire will make you start all over again.
* At this step, you’ll get to view the wires to be fed in the RJ45 clipper to make it an Ethernet pinout.Untwist the twisted wires and place them on a flat surface. Ensure that they are even with one another, if not make use of the wire cutters.
* Make sure that the wires are 1/2″ in length because more than this will lead to disadvantages of crosstalk experienced on the Ethernet pinout.
* Hold the RJ45 clipper facing down and away from you. Take the wires and push them into the RJ45 connector. This works well if the wires are flat. Immediately after doing this, you’ll be closer to having a fully functional Ethernet pinout but there is huge need to double check the order of the wires.
* Check the color orientation and if one or more falls out of place you need to start all over again. The minute you recognize that the set objectives are well done you can use the crimping tool to permanently fix the wires to the clipper.
You can do this at both ends and am sure at the end of the process your Ethernet pinout will work to full satisfaction.
An overview of Ethernet Pinout cables.
As technology changes over the years, so do the types and amounts of data required to be transmitted over an Ethernet pinout cable. The following is an overview of each of the active cable categories deployed most commonly today, and the applications to which each category of Ethernet pinout cable is primarily used.
Most Common Ethernet pinout cable categories
Cat 5 (10/100/1000MbE) Category 5 Ethernet pinout cable consists of twisted pair wiring used for carrying signals and supports frequencies up to 100Mhz. This type of cable is commonly used in computer networks to complete Ethernet pinout connections. Cat 5 can also carry signals for telephony and video, but has limitations on data load. The cable is commonly connected using a punch down block and a modular connector attached. Most Category 5 cables are unshielded, relying on the twisted pair design and differential signaling for noise rejection. Cat 5 can be used for speeds at 10/100 Ethernet for up to 100 meters and 10 meters or less for 1000MbE.. Cat 5 is currently considered an outdated standard and is commonly being replaced by Cat 5e (enhanced) for current applications.
Cat 5e (10/100/1000MbE) Category 5e (enhanced) Ethernet pinout cable provides support for frequencies up to 100Mhz, and also consists of twisted pair wiring used for carrying signals. Cat 5e is similar to the description above for standard Cat 5 with the following enhancements. The enhanced electrical performance of Cat 5e ensures that the cable will support applications that require additional bandwidth, such as gigabit Ethernet or analog video. Cat 5e is completely backward compatible with current Cat 5 equipment.
Category 5e generally provides the best price for performance. Depending on your network requirements and future growth, Cat 6 or higher might be a better choice as it usually does not cost much more.
Cat 6 (10/100/1000MbE/10GbE) Category 6 provides support for a frequency of 250Mhz. Cat 6 is an Ethernet pinout cable standard for Gigabit Ethernet and other network physical layers. The main increase in performance with Cat 6 cable comes directly from the increased wire size of 22 AWG. Cat 6 is backward compatible with both Cat5/Cat5e, and Cat 6 Ethernet pinout cables are normally terminated in 8P8C modular connectors. If Cat 6 rated patch cables, jacks, and connectors are not used with Cat 6 wiring, the overall performance will be degraded to that of the cable or connector. Cat 6 allows for 10/100/1000 use up to 100 meter cable length, and with 10GbE over shorter distances of 10 meters or less.
Cat 6a (10/100/1000MbE/10GbE) Category 6a or “Augmented” Cat 6 is different from standard Cat 6 cabling, in that it can support frequencies up to 500Mhz. The higher frequency support of Cat 6a will allow for better quality transmission of real time traffic as it relates to video and telephony. Cat 6a will support up to 10GbE with a length up to 100m.
Newest Technology in Ethernet pinout cable categories
Cat 7 10/100/1000MbE/10GbE/100GbE Category 7 is also known as “Class F” Ethernet pinout cabling, defined by a different standards body than Category 5 – 6a. It supports frequencies up to 600Mhz and may support the upcoming 100GbE standard. Cat 7 can transmit large amounts of information and is also able to better protect the signals traveling over the cable. The shielding as well as the tighter twists of the pairs in Cat7 and cable lessens the effects of crosstalk and EMI. Cat 7 is not widely used today as Cat 5e & Cat 6 provide the support of most bandwidth requirements today. As technology evolves, we expect to see Cat 7 more relevant in the data center and desktop connections.
Cat 7a (Speeds TBD) Category 7a “Augmented” is an upcoming standard with the expectation to allow for frequencies of up to 1000Mhz. Cat7a will be suitable for multiple applications including the transmission of Cable Television (CATV).The supported bandwidth speeds are yet to be published, and as new information is available, we will update this site to provide the latest Ethernet pinout configuration.
You should be able to identify the category of your Ethernet pinout cable by looking at the markings on the outer sheath. The category should be clearly identified, and is always easier to see on a lighter colored cable. For Ethernet pinout cabling, it is recommended to not order anything under the Cat 5e standard. Keep in mind that Cat 6 Ethernet pinout cabling is also close in cost comparison to Cat 5e, and depending on your future network needs, it may be a better choice to look into Cat 6 if your growth and requirement demand it.
It is a huge requirement for anyone who individually wants to solve Ethernet pinout problem to have broad background knowledge about it. One has to especially need to know about color coding used on these cables because there are factors used to handpick individual wires. Wrong placement of these wires will make the Ethernet pinout transmission impossible.
Discussion on Ethernet pinout structure on cable types
There are two types of Ethernet cables which include the straight-through cable and crossover cable. Both of these two types of cables are included in a “Category” of cable, which will be covered in the following article: “Ethernet Pinout Cable Category Description“. Straight-through cable technology was first applied in the year 1995 while that of crossover cable standard was ratified in 2002.The Ethernet pinout for these two cable types is very different from each other. Straight-through cables are majorly used as patch cords in Ethernet connections. Crossover cables are used to connect two Ethernet devices or hubs directly.
Types of Ethernet pinouts imposed on these two types of cables are much different thus it’s required of you to know that in a crossover cable’s Ethernet pinout, one end is of T-568A standard and the other is T-568B standard. Another way to do this is to switch the green in the wires with orange set of wires. This can be done by switching solid green with solid orange while green/white with orange/white. Take a look on your Ethernet pinout to make this a possibility.
Tips on Ethernet pinout
Here are some of the tips important for you in order to be well acquitted with Ethernet pinout technology. The first tip for you is to know that the Ethernet pinouts on straight-through cables are of the same structure. Those in crossover cables are different. Odd numbered pins in Ethernet pinouts are striped while that of even are solid in color.
When you take a closer look on your Ethernet pinout with the RJ45 facing away from you, brown wire is usually on the right and the first pin is located on the left. The wires used on the Ethernet pinout are normally 0.5″ to prevent crosstalk; this phenomenon is very disadvantageous to network connectivity.
Theory of Ethernet pinout structure
Ethernet pinout has 8 pins with different functions. Pin one is used for data where its transmitter is positive in nature. On straight-through, this pin is connected to pin one of the hub that has a positive receiver. Pin one of crossover cable is connected to another pc on pin three that is of positive receiver. This pin is composed of green/white wire.
Pin two of the Ethernet pinout which a solid green wire is of data that has a negative transmitter. On a straight-through cable, the pin is connected to pin 2 of the hub that has a negative receiver. On a crossover cable the pin is connected to pin six that has a negative receiver.
Pin three is composed of orange and white wire and has a positive receiver. Pin four has a solid blue wire and is used for ground. Pin 5 which also is used for ground has blue and white coloring. Pin 6 is solid orange in color and is also used for data. Pin 7 composed of orange and white coloring is used for power while pin 8 is composed of solid brown.
In my research on Ethernet Pinout, I have discovered a number of acronyms which I wanted to capture here for reference.
See the below Ethernet pinout acronyms which are most commonly used in the industry today. I will continue to add more as advances in technology are made to within the industry. Please leave a comment to let me know if you are aware of a acroynm that should be added to the list, and I will make the list is updated accordingly.

To fully enjoy the benefits of an Ethernet pinout you need to consider the network requirements in place. Benefits enjoyed here are broad thus you need to take these into account.
How to ensure your Ethernet pinout meets network requirements
There are three things you need to consider before you start using your Ethernet pinout, they include network specifications, workspace distance and your budget. Your network specification is very important because it will determine the actual number of cables needed requiring an Ethernet pinout.This could range from few to many, of course depending on the true size of your network.
Distance of your workspace is another important aspect in determining how well your Ethernet pinout will be connected. You cannot make use of your Ethernet pinout very well if you have too short of a cable. The right length cable will aide in preventing the Ethernet pinout from unplugging here and there. The exact distance measurements will help in cutting out the best measurement of the cable which also will prevent damage to the Ethernet pinout.
Budgetary constraints also are important and this factor will work well if you are dealing with a multiple number of computers. The facts will enable you to devise a plan on how the distribution of Ethernet pinout will be done for he cabling requirements of your network to ensure cost effectiveness.
How to plug your Ethernet pinout to your pc
Safety must be uphold when making use of the Ethernet pinout.I am going to provide you with a clear way to get the best out of it. The first step is for you to power down your computer. Position your computer at a position well defined for the Ethernet cable to make contact with. Make sure you have space enough for your computer to move.
Pick up your Ethernet pinout and slot it in the port located at the sides or back of your computer. Don’t worry the jack will automatically lock in the computer. At this stage you are free to start up your computer where on your task bar you’ll see that the computer recognizes it.
Major problems experienced with Ethernet pinout
There are problems that you may experience when making use of the Ethernet pinouts. Lack of connectivity will be experienced. Major problems leading to this includes;
1. Improper cables-The Ethernet pinout will not transmit if you are using improper category of cable. You can find yourself using the crossover to connect to a hub or straight-through to directly connect the computers. Make sure you counter check to make sure you use proper cable for ideal use.
2. Improper connections where your Ethernet pinout is not plugged in correctly. You can recognize this by looking at your taskbar to see if the computer has recognized it.
3. Ethernet pinout damage experienced when the wires tend to be detached. This is experienced if they are loose thus you need to wiggle the cable for re-establishment of connection.
4. The forth problem that can prevent your Ethernet pinout from transmitting is presence of cable damage. The best solution to approach on this is to replace the cable.
5. The last problem is signal interference generated by other devices such as mobile phones thus it’s good to ensure that they are kept away when doing connectivity.
Ethernet cables are majorly used to connect computers to a network, modems or routers. They are normally thick and full duplex in nature where communication is both ways. These cables normally resemble phone cords where these cables can be categorized as crossover or straight. Ethernet cables have the capability of transmitting 100 MB of information per second.
Ethernet pinout is a collection of pins at the end of the cable where logical functions and signals are allocated to. If you take your Ethernet cable and cut it you’ll find 8 unique individual wires composed of 8 different colors. These are the wires fed into a jack known as RJ45 which make the Ethernet pinout.Order of these arrangements is determined by an Ethernet pinout.
Composition of the Ethernet pinout
Wires found In the Ethernet pinout
As I said earlier, the Ethernet cable is composed of 8 individual wires of different color composure. These wires differently have unique functions in Ethernet pinout.The colors include blue, blue and white striped, green, green and white striped, brown, brown and white striped, orange, and orange and white striped.
These colors are not same on all Ethernet pinout because of the two main types of the cable. The two types of Ethernet pinout include T568A and T568B.T568A Ethernet pinout have identical ends while the T568B have ends that are different from each other.
Having Ethernet pinout is very advantageous because it has been known to hugely save money. If you want to know the category of the cable if either is cross-over or straight-through, look at the Ethernet pinout. If your Ethernet pinout has first and second pin orange, then the cable is T568B (cross-over).If the said wires are green then the cable is a straight-through. If the two ends are indifferent then the cable is a cross-over in nature.
Dangers of Doing Ethernet pinout wiring wrongly
Is you are not well acquitted on proper way of doing wiring on the Ethernet pinout; you will suffer some repercussions such as.
* Non-connectivity where the function of the Ethernet pinout is limited because of bad placement of the wires. Every wire has its own functions which hugely depend on the position. These functions are unique to the wires so make sure you know more about its alignment.
* If the Ethernet pinout is used on radio you’ll find that the radio isn’t performing or negotiating correctly. Connections to the radio get to be of short distance giving you much disadvantage in terms of radio communication.
* The Ethernet cable is limited to few duplex values which normally set to 10 Half Duplex (HDX) or 10 Full Duplex (FDX).The functionality of the Ethernet pinout pins includes; pin 1-3 are for data but of different types. Pin 6 is for data, pin 4 and 5 is for ground and 7 and 8 is based for power.
In order to build up your Ethernet pinout, ensure that you are knowledgeable with the wiring connectivity in place. Ensure that they uniquely fall in their correct places based on the category of Ethernet cable.
