Cat 5 Type B Wiring. T568b is very common in the usa. The different types of cables (category or cat) offer increasingly faster transmit and receive speeds, this is achieved by increasing the wire twists, better shielding, drain wire and increased wire diameter.
We will then identify each cable by plugging in a wire tester to each cable. How to terminate a cat 5 cable: Cat 5e is rated for gigabit, it's just has more delay and skew than cat 6 due to the differences in twist and such.
The image below shows the 2 standard configurations for cat 5(and 6).
Both are appropriate for high speed data, though 568b is somewhat more common for installed. Wire both ends identical, 568b or 568a. How to terminate a cat 5 cable: Cat 5e is rated for gigabit, it's just has more delay and skew than cat 6 due to the differences in twist and such.
