2. Category 5 cable - Wikipedia

   en.wikipedia.org/wiki/Category_5_cable

   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. [11]

3. Ethernet physical layer - Wikipedia

   en.wikipedia.org/wiki/Ethernet_physical_layer

   4B5B MLT-3 coded signaling, Category 5 cable using two twisted pairs. The specifications are largely borrowed from FDDI's TP-PMD. [12] As of 2018, still very popular. 100BASE-T4: 802.3u-1995 (23) 8P8C (IEC 60603-7) 8B6T PAM-3 coded signaling, Category 3 cable (as used for 10BASE-T installations) using four twisted pairs. Limited to half-duplex.

4. 2.5GBASE-T and 5GBASE-T - Wikipedia

   en.wikipedia.org/wiki/2.5GBASE-T_and_5GBASE-T

   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]

5. ANSI/TIA-568 - Wikipedia

   en.wikipedia.org/wiki/ANSI/TIA-568

   The standard specifies how to connect eight-conductor 100-ohm balanced twisted-pair cabling, such as Category 5 cable, to 8P8C modular connectors (often referred to as RJ45 connectors). The standard defines two alternative pinouts: T568A and T568B. ANSI/TIA-568 recommends the T568A pinout for horizontal cables.

6. Power over Ethernet - Wikipedia

   en.wikipedia.org/wiki/Power_over_Ethernet

   Standards-based Power over Ethernet is implemented following the specifications in IEEE 802.3af-2003 (which was later incorporated as Clause 33 into IEEE 802.3-2005) or the 2009 update, IEEE 802.3at. The standards require Category 5 cable or better for high power levels but allow using Category 3 cable if less power is required. [27]
