The increasing demand for higher bandwidth to support Big Data has driven the need for ever-increasing Ethernet speeds, starting with 10 Gig in 2004 to the introduction in 2010 of 40 Gig with 4 fibers transmitting and 4 fibers receiving at 10 Gbps (40GBASE-SR4) and 100 Gig with 10 fibers transmitting and 10 fibers receiving at 10 Gbps (100GBASE-SR10).
