100BASE-FX SFP for legacy fast-ethernet links

The Brute Networks HP JF833A compatible transceiver adds a 100 Mbps fibre port to switches and routers that still run 100BASE-FX. It targets network teams maintaining older campus or metro-edge segments where gigabit uplinks are not required. The module is coded for HP equipment and initialises without extra configuration. It suits environments that need a low-cost, drop-in replacement for an original HP JF833A.

Multi-mode reach limited to two kilometres

The transceiver operates at 1310 nm over multi-mode fibre with an LC duplex connector and is rated for a maximum link distance of 2 km. At 100 Mbps the interface cannot carry modern aggregated traffic loads and will saturate quickly on busy uplinks. The optical budget assumes standard multi-mode cable plant; longer runs or single-mode fibre will not work. Digital diagnostic monitoring is supported for real-time link health visibility.

Verify switch slot coding

Confirm the target device accepts third-party SFP modules coded for HP JF833A; some vendors lock ports to first-party optics only. Ensure the existing cabling is multi-mode with LC duplex terminations and that the planned link length stays within the 2 km rating. The module operates in a commercial temperature range of 0 to 70 °C, so outdoor or industrial enclosures may exceed its limits.
