Single-mode SFP for 1000 Mbps links

The Black Box LFP414 is a single-mode SFP transceiver built for 1000Base-X optical fibre connections. It supports throughput up to 1250 Mbps and is suited to network teams deploying or extending Gigabit Ethernet links over single-mode fibre infrastructure.

Hot-pluggable module for SFP slots

The transceiver fits standard SFP slots on most network devices and can be inserted or removed without powering down the host equipment. It reports basic link characteristics including fibre type, link length, wavelength and bit rate, while extended diagnostics add temperature, TX and RX power, voltage and bias current readings.

Diagnostic data under continuous traffic

Extended diagnostics remain active during sustained load, providing ongoing visibility into temperature, optical power levels, voltage and bias current. This telemetry helps operators monitor link health over time rather than relying on a single burst measurement.

Questions about this item

What throughput limit appears first when the LFP414 runs at full load for long periods?

The transceiver supports up to 1250 Mbps, so sustained traffic at 1000 Mbps Ethernet line rate is the practical ceiling before congestion.

How much heat or power does the module add when it stays in a switch all day?

Hot-pluggable SFP design draws power from the host slot; extended diagnostics report temperature, voltage and bias current so you can monitor thermal load.

Which slot type must the switch or router already have for this transceiver to work?

It requires a standard SFP slot that accepts 1000Base-X single-mode optics with an LC connector.
