Product identity

The Finisar FTLF8519P2BNL is a 1000Base-SX SFP transceiver module built for Gigabit Ethernet and Fibre Channel links. It targets network engineers and integrators who need a hot-pluggable, multi-mode fibre interface for switches, routers or storage gear.

Compatibility checks

Verify that your host equipment accepts SFP modules compliant with the MSA and supports digital diagnostics over the 2-wire serial bus. Confirm the link uses LC duplex patch cords terminated for 50/125 µm or 62.5/125 µm multi-mode fibre before ordering.

Sustained operation

The module meets IEEE 802.32 and Fibre Channel FC-PI-2 Rev. 5.03 specifications for continuous data networking traffic. RoHS-compliant, lead-free construction per Directive 2002/95/EC and Application Note AN-2038 ensures stable thermal behaviour during extended duty cycles.

Questions about this item

Does the FTLF8519P2BNL transceiver ship with LC duplex patch cables or must they be purchased separately?

The module provides one LC duplex port for 1000Base-SX links; fibre patch cables are not included and must be sourced separately to match your 50/125 µm or 62.5/125 µm multi-mode plant.

Should I choose this 1000Base-SX model or a 1000Base-LX variant for my multi-mode installation?

Select the 1000Base-SX version when the link runs over 50/125 µm or 62.5/125 µm multi-mode fibre; 1000Base-LX modules are designed for single-mode cable and would not suit this plant.

What does the 1000Base-SX rating mean for actual throughput when the transceiver is installed in a switch?

The module delivers a 1 Gbit/s Ethernet signal compliant with IEEE 802.32 over multi-mode fibre, so the port negotiates to 1000 Mbps full-duplex when linked to a compatible Gigabit Ethernet port.
