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]
Through the use of power over Ethernet (PoE), power can be carried over the cable in addition to Ethernet data. Cat 5 is also used to carry other signals such as telephony and video. [17] In some cases, multiple signals can be carried on a single cable; Cat 5 can carry two conventional telephone lines as well as 100BASE-TX in a single cable.
Cat-5: Energy-efficient Ethernet variant of 10BASE-T using a reduced amplitude signal over Category 5 cable, completely interoperable with 10BASE-T nodes. 10BASE-T1L: 802.3cg-2019 (146) IEC 63171-1, IEC 63171-6 1000 m Ethernet over a single twisted pair - long reach, for industrial applications 10BASE-T1S: 802.3cg-2019 (147) 25 m
IEEE 802.3 is a working group and a collection of standards defining the physical layer and data link layer's media access control (MAC) of wired Ethernet.The standards are produced by the working group of the Institute of Electrical and Electronics Engineers (IEEE).
Since common Category 5 cable has four pairs, it is possible to use the spare pairs (pins 4–5, 7–8) in 10- and 100-Mbit/s configurations for other purposes. The spare pairs may be used for power over Ethernet (PoE), for two plain old telephone service (POTS) lines, or for a second
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.
