10GBase Ethernet is the most
recent and fastest of the Ethernet standards. It's
intended to connect
servers or switches over short
distances, up to 50 feet, using coaxial cable. It gets its
name because
it is intended to run over CX4, or 4 pairs of
twin axial copper wiring. It has a nominal data rate of
10Gbit/sec, 10 times as fast as gigabit Ethernet. It is
also referred to as 802.3ak.
