By reducing the original signal rate to 1 ⁄ 4 or 1 ⁄ 2, the link speed drops to 2.5 or 5 Gbit/s, respectively. [5] The spectral bandwidth of the signal is reduced accordingly, lowering the requirements on the cabling, so that 2.5GBASE-T and 5GBASE-T can be deployed at a cable length of up to 100 m on Cat 5e or better cables. [6] [7]
Each 1000BASE-T network segment is recommended to be a maximum length of 100 meters (330 feet), [5] [a] and must use Category 5 cable or better (including Cat 5e and Cat 6). Autonegotiation is a requirement for using 1000BASE-T [ 6 ] according to Section 28D.5 Extensions required for Clause40 (1000BASE-T) . [ 7 ]
Cross section of a cat 5e cable. The Category 5e specification improves upon the Category 5 specification by further mitigating crosstalk. [9] The bandwidth (100 MHz) and physical construction are the same between the two, [10] and most Cat 5 cables actually happen to meet Cat 5e specifications even though they are not certified as such.

The line encoding used by 10GBASE-T is the basis for the newer and slower 2.5GBASE-T and 5GBASE-T standard, implementing a 2.5 or 5.0 Gbit/s connection over existing category 5e or 6 cabling. [51] Cables that will not function reliably with 10GBASE-T may successfully operate with 2.5GBASE-T or 5GBASE-T if supported by both ends.

A crossover cable may also be used to connect two hubs or two switches on their upstream ports. Because the only difference between the T568A and T568B pin and pair assignments are that pairs 2 and 3 are swapped, a crossover cable may be envisioned as a cable with one modular connector following T568A and the other T568B (see TIA/EIA-568 wiring ...
