10 Gb/s SFP+ transceiver for multimode fibre
This Finisar FTLX8571D3BCL module provides a hot-pluggable SFP+ footprint for 10 Gigabit Ethernet and 10 Gb/s Fibre Channel links. It operates at 850 nm with a duplex LC connector and supports data rates from 9.95 to 10.5 Gb/s over multimode fibre. The unit is RoHS-6 compliant and rated for commercial temperatures from 0 °C to 70 °C.
Steady-state operation at up to 10.5 Gb/s
Power dissipation stays below 1 W during continuous use across the full commercial temperature range. The uncooled 850 nm VCSEL laser maintains link integrity up to 300 m on 2000 MHz·km multimode fibre. Built-in digital diagnostics report temperature, voltage and optical power in real time via the two-wire serial interface.
Hot-plug installation with LC cabling
The transceiver inserts directly into any compliant SFP+ cage without tools or system reboot. A common issue is exceeding the 300 m reach on lower-grade multimode fibre or using single-mode patch cords by mistake. Ensure the host port supports SFF-8431 and SFF-8472 diagnostics for full monitoring capability.
