1 Gbps SFP transceiver for HP J4858D slots

This Brute Networks module is a 1000BASE-SX SFP transceiver built for multi-mode fibre links up to 550 metres at 850 nm wavelength. It targets network administrators adding or replacing optics in HP switches, routers or servers that accept the J4858D part number. The unit is MSA compliant and coded for full HP compatibility.

Check SFP port type and fibre patch cables before

Verify that the host equipment provides an SFP cage rated for 1000BASE-SX optics and that the intended link uses multi-mode fibre with LC duplex connectors. The transceiver operates in a commercial temperature range of 0 to 70 °C, so confirm the installation environment stays within those limits. Digital optical monitoring is supported for link diagnostics.

LC duplex connector and MSA coding simplify

The LC duplex interface matches standard multi-mode patch cords, while the pre-programmed EEPROM lets the module initialise identically to an OEM unit without extra configuration. Mixed deployments with other OEM or third-party transceivers are supported, reducing spares complexity. A lifetime warranty covers the part for its service life.

Questions about this item

Does the module ship with cables or patch leads, or do I need to source LC duplex fibre separately?

Only the transceiver is supplied; you must provide your own LC duplex multi-mode patch cables to complete the link.

Is this the only reach option available for the J4858D part number?

The J4858D is specified at 550 m over multi-mode fibre at 850 nm; longer-reach variants carry different part numbers.

What does the 550 m figure mean when the transceiver is installed in a live switch?

It guarantees a 1 Gbps link over standard multi-mode fibre up to 550 m at 850 nm, provided the fibre plant meets the same specification.
