A method, an apparatus and a system for gigabit Ethernet (GbE) using only 2 pairs of wires for a single communications link are described. This network communication may be referred to as 2-pair 1000Base-T. GbE using only 2 wire pairs per link may offer increased port density over a conventional 1000Base-T link. As an alternative, 2-pair 1000Base-T may also provide increased link bandwidth over the existing 1000Base-T standard. When a given number of conventional links in a system are replaced by the same number of 2-pair 1000Base-T links, the system bandwidth may also be consequently increased. Transformers and power supplies may be combined with GbE utilizing only two wire pairs to provide power over Ethernet (PoE) solutions. |
