Gigabit Ethernet (Gig E) was another step in the evolution of Ethernet. When Ethernet started it had speeds of up to 10 Mbps while Fast Ethernet stepped that up to 100 Mbps. Gigabit Ethernet again provided a ten-fold increase with speeds of up to 1 gigabit (1000 Mbps). Like Fast E, Gig E also requires that you connect your businesses network directly to the carrier's network.
Extremely fast. With up to 1 Gbps of bandwidth, a Gig E circuit can support all but the very largest of bandwidth requirements. It can be used by office buildings, research institutions, or other large enterprises for any of their Internet needs
A Gig E circuit requires that the carrier's router be located very close to your office. This has limited the growth as most carriers will only place a router with very large businesses, universities, or office buildings with several tenants. Typically, Gig E circuits start at around $20 a megabit with minimum commitments required.
