HP-compatible SFP transceiver for 10 km

This new Brute Networks module matches the HP J4859D part number and delivers 1 Gbps over single-mode fibre. It is built for network engineers who need a cost-effective way to populate an SFP slot on a router, switch or server without paying OEM list prices. The transceiver initialises with HP-specific configuration data so it is recognised immediately by the host equipment.

10 km reach at 1310 nm wavelength

The single specification that decides fit is the 10 km maximum distance on single-mode fibre at 1310 nm. If your link exceeds that span or requires multi-mode cabling, this module will not meet the requirement. The LC duplex connector and 1 Gbps transfer rate are fixed by the 1000BASE-LX standard, so verify the distance and fibre type before purchase.

Digital optical monitoring and MSA compliance

The unit includes Digital Optical Monitoring so the host can report real-time temperature, voltage and optical power levels. Full MSA compliance means the transceiver can be mixed with other OEM or third-party modules in the same chassis without interoperability issues. A commercial temperature rating of 0 to 70 °C covers standard data-centre and wiring-closet environments.
