Frequently Asked Questions

What is the difference between 1000Base-LX and 1000Base-SX?

1000Base-LX uses 1310nm single-mode fibre for long-reach links up to 10km; 1000Base-SX uses 850nm multimode fibre for short-reach links up to 550m. Use LX for inter-building or long-distance campus links.

Is this compatible with Cisco switches?

The FTRJ-1319-7D-2.5 is a Finisar OEM transceiver. Some Cisco switches require Cisco-branded or approved transceivers — verify compatibility or use a Cisco-compatible variant if required.

Can this be used for Fibre Channel SAN connectivity?

Yes — the FTRJ-1319-7D-2.5 supports 2Gb Fibre Channel in addition to 1000Base-LX Gigabit Ethernet, making it suitable for 2Gb FC SAN HBA and switch connectivity.

The Finisar FTRJ-1319-7D-2.5 delivers 2.125Gb/s 1000Base-LX and 2Gb Fibre Channel optical connectivity over 10km single-mode fibre — a reliable, hot-pluggable SFP transceiver for enterprise SAN and long-reach Gigabit Ethernet deployments.
