It interfaces a network device mother board (for a switch, router, media converter or similar device) to a fiber optic or copper networking cable. It is a popular industry format supported by many network component vendors.
E-link fiber optic SFP transceivers are certified to be used with CISCO, BROCADE, JUNIPER, HP (select models), NORTEL, EMC, QLOGIC and other equipment.

The 1000BASE-LX/LH SFP, compatible with the IEEE 802.3z 1000BASE-LX standard, operates on standard single mode fiber-optic link spans of up to 10km and up to 550m on any multimode fibers. When used over legacy multimode fiber type, the transmitter should be coupled through a mode conditioning patch cable.
