IMSourcing FTLX8571D3BCV SFP+ transceiver

Dual-Rate SFP+ for 1G and 10G Ethernet

The IMSourcing FTLX8571D3BCV is a Finisar dual-rate SFP+ transceiver built for 1-Gigabit and 10-Gigabit Ethernet links over multimode fibre. It targets network engineers deploying 10GBASE-SR/SW or 1000BASE-SX connections in compatible switches and routers. The hot-pluggable module uses an LC duplex interface and complies with SFF-84311 and IEEE 802.3-2005 standards. It is not suited for native 1G SFP ports that lack dual-rate support.

Low-Power Hot-Pluggable Operation

As a limiting receiver module, the transceiver draws minimal power during normal link operation and produces no audible noise because it has no moving parts. Digital diagnostics are accessible through the 2-wire serial interface defined in SFF-84724, allowing real-time monitoring of temperature, voltage and optical levels without service interruption. The RoHS-compliant, lead-free construction meets Directive 2002/95/EC5 and Finisar Application Note AN-20386 requirements for environmental safety.

LC Duplex Multimode Compatibility

The single LC duplex 10GBase-X port determines whether this transceiver fits the target link; it requires multimode fibre patch cables and a host port that accepts 1G/10G dual-rate SFP+ modules. Buyers needing single-mode reach, native 1G-only SFP slots or a different connector type must select an alternative module. Host board designers using EDC PHY ICs should verify the manufacturer's recommended settings for interoperability with a limiting module.
