Transceiver for 155 Mbps fibre links

The Black Box LFP403 SFP module converts an SFP slot to a single-mode fibre interface using a 1310 nm wavelength. It operates at speeds up to 155 Mbps and reaches distances of 30 km over LC connectors. The unit is transparent to data protocols, so it works with any network standard running at the supported rate. Extended diagnostics and an operating range of -40 to 176F (-40 to +85C) are included.

Check SFP slot and fibre type before ordering

Verify that the host equipment accepts SFP transceivers and supports 100Base-X signalling. The link requires single-mode fibre terminated with LC connectors on both ends. Ensure the optical budget matches a 30 km span at 1310 nm. The module weighs approximately 0.04 lb and measures 2.2 by 0.6 by 0.5 inches, so confirm physical clearance in the chassis.

Extended diagnostics and wide temperature range

Built-in digital diagnostics let administrators monitor optical power, temperature and voltage in real time. The industrial-grade rating of -40 to 85C allows deployment in unconditioned cabinets or outdoor enclosures. TAA compliance and WEEE certification satisfy government procurement and environmental requirements. A one-year limited warranty covers the transceiver.

Questions about this item

Does the LFP403 include the LC patch cable or must I buy it separately?

The transceiver has an LC receptacle; the matching single-mode patch cable is not included and must be purchased separately.

How do I decide between this 30 km 1310 nm model and a shorter-reach or multi-mode version?

Choose this LFP403 when the link is single-mode fibre up to 30 km at 1310 nm; shorter-reach or multi-mode needs require a different wavelength or distance rating.

Will the 155 Mbps rating limit throughput on a 100Base-X switch port?

The module is transparent to data up to 155 Mbps, so a 100Base-X port will run at its full 100 Mbps line rate without bottleneck.
