1250 Mbps SFP Transceiver

The Black Box Innovations LFP411 is a hot-pluggable SFP transceiver designed for 1250 Mbps throughput over multimode fibre. It operates at an 850 nm wavelength with an LC duplex connector and supports link distances up to 550 m. The module is sold individually and weighs .09 units.

Suits 1000 Mbps Ethernet links

This transceiver suits networks running 1000 Mbps Ethernet where extended diagnostics are required. It reports temperature, TX and RX power, voltage, and bias current alongside basic link characteristics. It is not for single-mode fibre runs, longer distance requirements, or higher-speed interfaces such as 10 Gbps.

Stable under continuous traffic

Extended diagnostics provide continuous visibility into module health during sustained load. Real-time monitoring of temperature, voltage, and optical power helps identify drift before errors appear. Hot-pluggable operation allows replacement without interrupting adjacent ports or the wider network.

Questions about this item

What type of SFP slot must my switch or router provide for the LFP411 to be recognised?

The transceiver uses the standard SFP form factor, so any MSA-compliant SFP cage that accepts hot-pluggable modules will recognise the LFP411.

Will the LFP411 establish a 1000-Mbps Ethernet link over my existing 850-nm multimode fibre patch cables?

Yes, the module operates at 850 nm on multimode fibre and supports 1000-Mbps Ethernet up to 550 m, matching common OM2/OM3 patch leads.

How can I confirm the LFP411 is reporting temperature, TX power, RX power, voltage and bias current after installation?

Query the extended diagnostics registers through your switch management interface; the LFP411 exposes those real-time values once seated in the SFP slot.
