What is the standard Ethernet cable wiring?
Two different wiring standards exist for wired Ethernet: T568A (A wiring) and T568B (B wiring). A and B wiring offer the same electrical properties and either standard can be used. StarTech.com uses the T568B wiring standard for all of the straight-through Ethernet cables.

How many color wires are in a standard Ethernet cable?
Like all cables, ethernet cables can come in several different colors. One color isn’t “better” or “faster” than another cable, but the colors can help denote the intended application. The most common colors seen with ethernet cables are grey, blue, yellow, orange, and white.
Are patch cables wired A or B?
Many networking professionals use the term patch cable to refer to any kind of straight through cable. So a patch cable is often called a straight through cable. In other words, patch cable does not change or swap along its way. Both ends use the same wiring standard: T-568A or T-568B.
Why does Ethernet cable have 8 wires?
More wires could lead to too expensive cables so 8 was chosen as a compromise. RJ31 to RJ61 (including RJ45) all use the 8P8C connection; so it was already produced and reasonably priced, but not commonly found in homes. Ethernet did the simple thing, grabbed what hardware was cheap and laying around.
What are the two wiring standard A in patch cable?
There are two wiring standards for UTP cables, called “T568A” (also called “EIA”) and “T568B” (also called “AT” and “258A”).
How do I know if I have T568A or T568B?
If you are looking at a patch cord the easiest way to tell which standard you have is to look at the first two pins, if they are green, it is T568A, and if they are orange, you have T568B.
Why are there 8 wires in Ethernet cable?
What is the difference between a cat 6 and cat 8 Ethernet cable?
Cat8 is the fastest Ethernet cable yet. Its data transfer speed of up to 40 Gbps is four times faster than Cat6a, while its support of bandwidth up to 2 GHz (four times more than standard Cat6a bandwidth) reduces latency for superior signal quality.
What is the difference between an A or T568A and B or T568B wired Ethernet cable?
T568A and T568B are the termination standards used by Internet backbone infrastructure, Internet providers and all the way down to homeowners or businesses. The only real difference between these two pin-to-pair assignments are the green and orange pairs. These two sets are swapped in the cable.
How many wires does Ethernet actually use?
8
Inside the ethernet cable, there are 8 color coded wires. These wires are twisted into 4 pairs of wires, each pair has a common color theme.
Which four wires are used in Ethernet?
The RJ45 data cables we use to connect computers to a Ethernet switch is straight-through cables. As noted above, the RJ45 cable uses only 2-pairs of wires: Orange (pins 1 & 2) and Green (pins 3 & 6). Pins 4, 5 (Blue) and 7, 8 (Brown) are NOT used.
Do I need all 8 wires for ethernet?
The first major difference is the gigabit standards require the use of all four pairs (all eight wires), unlike Fast Ethernet which only utilizes two pairs of wires. As a result, in Gigabit Ethernet, all four pairs must be crossed when building a Crossover cable. That said, Gigabit Ethernet requires Auto MDI-X.
