Gigabit Ethernet, which is standardized by the IEEE as the 802.3z standard, is a term describing various technologies for transmitting Ethernet frames at a rate of a Gigabit per second. The 1000BASE SFP transceiver is an important part in Gigabit Ethernet applications, which is a hot-swappable input/output device that plugs into a Gigabit Ethernet port/slot, linking the port with the network. There is a number of 1000BASE SFP transceivers that are available in accordance with the customer application and distance capability required.
Depending on the cable material, Gigabit Ethernet can be classified into fiber-based Gigabit Ethernet and copper-based Gigabit Ethernet. Different 1000BASE SFP transceivers may used in different kinds Gigabit Ethernet.
1000BASE SFP Transceivers in Fiber-based Gigabit Ethernet
In fiber-based Gigabit Ethernet, 1000BASE-X is used in industry to refer to Gigabit Ethernet transmission over fiber. 1000BASE-X is a group of standards for Ethernet physical layer standards, including 1000BASE-SX, 1000BASE-LX, 1000BASE-LX10, 1000BASE-BX10 or the non-standard 1000BASE-EX and 1000BASE-ZX implementations. Different 1000BASE SFP transceivers may be used in different standards.
