Finisar FTRJ-8519-7-EXT: 850nm shortwave SFP for 1000BASE-SX Gigabit Ethernet and 1 or 2Gb Fibre Channel, LC duplex multimode.

The Finisar FTRJ-8519-7-EXT is a small form-factor pluggable optical transceiver working at 850nm over multimode fibre, serving 1000BASE-SX Gigabit Ethernet and 1Gb or 2Gb Fibre Channel from the same module. It presents an LC duplex optical interface, runs from a single 3.3V rail and stays under 750mW dissipation.

The EXT designation marks the extended temperature build, rated well beyond the commercial range, which is why parts like this turn up in storage arrays and switch line cards rather than desktop equipment. Shortwave modules of this class reach roughly 500 metres on 50 micron multimode fibre and around 300 metres on 62.5 micron. Host switches and directors frequently read the vendor identification held in the module EEPROM, so confirm your platform accepts a Finisar-coded part before ordering.

Finisar merged with II-VI in 2019 and that transceiver business now trades as Coherent, so modules of this age carry the original Finisar marking.
