SFP Transceiver for Gigabit Ethernet

Gigabit Ethernet Standards

Gigabit Ethernet (GbE or 1 GigE), defined by the IEEE 802.3-2008 standard, is a term describing various technologies for transmitting Ethernet frames at a rate of a gigabit per second (1million bits per second). There are a variety of Gigabit Ethernet Standards.

1000BASE-T SFP

1000BASE-T SFP, compliant with IEEE 802.3 1000BASE-T standard, operates on standard Category 5 with a maximum length of 100 m (328 ft) and supports 10/100/1000 auto negotiation and auto MDI/MDIX. It is cost-effective and easily maintained, which is commonly applied in the LAN
