SFP transceiver for 1000 Mbps Ethernet

The Black Box LFP411 is a small form-factor pluggable transceiver that adds a fiber interface to any switch or router with an open SFP slot. It operates transparently to data, so it works with any network standard running at speeds up to 1250 Mbps, making it suitable for 1000 Mbps Ethernet links in enterprise or campus environments.

LC duplex connector and 850 nm multimode fibre

A duplex LC connector provides a secure, low-profile connection for standard multimode patch cables. The 850 nm wavelength supports reaches up to 550 metres on OM2 or OM3 fibre, fitting typical building or data-centre runs. An industrial temperature rating of -40 to +85 °C (-40 to 176 °F) allows deployment in unconditioned cabinets or outdoor enclosures without active cooling.

Extended diagnostics for link monitoring

Built-in digital diagnostic monitoring reports real-time parameters such as optical power, temperature, voltage and bias current. Network managers can read these values through the host system to verify link health, troubleshoot degradation and plan maintenance before a failure occurs, reducing unplanned downtime on critical fibre segments.

Questions about this item

What throughput does the 850 nm LC SFP cap at in practice?

The transceiver handles up to 1250 Mbps and is designed for 1000 Mbps Ethernet links over multimode fibre.

What slot and patch-cord connector does the LFP411 need to fit?

It plugs into a standard SFP slot and terminates with an LC duplex connector for 850 nm multimode fibre.

How is the module installed and what step is often missed?

Insert the SFP until it clicks, then connect the LC patch cord; the step people miss is removing the dust caps from both the module and the cable ends before linking.
