10GBase-SR SFP+ Transceiver

The Finisar FTLX8571D3BCL is a hot-pluggable SFP+ module built for 10 Gigabit Ethernet links over multimode fibre. It uses an LC connector and complies with SFF-8431, SFF-8432 and IEEE 802.3ae 10GBASE-SR standards. Digital diagnostics are available through a two-wire serial interface per SFF-8472. The unit is RoHS compliant and lead-free per Directive 2002/95/EC.

Network engineers extending 10G links over

This module suits engineers deploying 10GBase-SR connections inside data centres or campus networks using multimode cabling. It is not suited for single-mode fibre runs, longer distance requirements beyond multimode reach, or line rates above 10G. Buyers needing different wavelengths, connector types or extended temperature ranges should look at other form factors.

Multimode fibre medium constraint

The single specification that decides fit is the multimode fibre medium. The transceiver operates at the 10GBase-SR wavelength window defined for short-reach multimode links. If the installed cabling is single-mode or the required reach exceeds the SR distance, this part will not establish a link.

Questions about this item

How can I confirm the 10GBase-SR link is operating correctly after installing the FTLX8571D3BCL?

The module provides digital diagnostics via the 2-wire serial interface specified in SFF-84724, allowing real-time monitoring of optical power, temperature, voltage and bias current to verify link health.

What is included with the FTLX8571D3BCL and what must be purchased separately?

The transceiver itself is supplied; LC duplex multimode patch cables and compatible SFP+ switch ports are required but not included.

Which Finisar 10GBase-SR variant should I choose for my multimode deployment?

The FTLX8571D3BCL is the SFP+ form-factor module compliant with SFF-84311, SFF-84322 and IEEE 802.3ae for 10 Gigabit Ethernet over multimode fiber.
