10G SFP+ Transceiver 300m Reach

The Black Box LSP421 is a hot-swappable SFP+ module designed for 10 Gigabit Ethernet links over multimode fibre. It operates at an 850nm wavelength and supports the 10GBASE-SR standard for data networking and optical network applications. The transceiver delivers a 11.32 Gbit/s line rate through a single LC duplex connector.

Upgrade from 1G SFP Links

This module replaces 1G SFP transceivers when bandwidth demand exceeds gigabit capacity across the same multimode plant. The jump is worth it when aggregation uplinks, server interconnects or storage fabrics require tenfold throughput without changing the existing fibre cabling. It is not suited for buyers who need longer reach than 300 metres or single-mode compatibility.

Multimode Distance Limit 300m

The 10GBASE-SR interface is bounded by modal dispersion in OM3 or OM4 multimode fibre, capping reliable operation at 300 metres. Beyond that distance, signal integrity degrades and a different optical standard becomes necessary. The module complies with RoHS and WEEE directives and carries extended diagnostics for link monitoring.

Questions about this item

What patch-cable connector does the LSP421 require to reach 300 m?

The module uses an LC duplex interface, so you need a multi-mode patch cord with LC connectors on both ends to complete the 300 m link.

Which slot type accepts this hot-swappable transceiver without powering down the switch?

Insert the LSP421 into any standard SFP+ cage; the hot-swappable design lets you install or remove it while the system remains powered on.

When should the transceiver be replaced if link errors appear on a 10GBASE-SR run?

Clean the LC end-faces first; if CRC errors persist after re-seating, replace the module because the 850 nm optics have degraded.
