HP JD119B compatible SFP transceiver for 1 Gbps

This module delivers a 1 Gbps Ethernet connection over single-mode fibre at a 1310 nm wavelength. It is built for network operators who need to extend a link up to 10 km between switches, routers or servers. The transceiver follows the 1000BASE-LX standard and is coded for full HP compatibility. It fits any standard SFP slot that accepts MSA-compliant optics.

Commercial temperature range with low power draw

Rated for 0 °C to 70 °C operation, the transceiver runs within the commercial temperature band without active cooling. Its SFP form factor keeps power consumption modest, so it adds minimal heat to a populated chassis. Front-panel LEDs show power, link activity, full-duplex status and speed, giving instant visual confirmation without extra monitoring tools. The LC duplex connector ensures a secure fibre interface.

Digital diagnostics and lifetime warranty included

Digital optical monitoring is built in, allowing real-time checks of received power, transmitted power, temperature, voltage and bias current through the host system. The module meets or exceeds MSA industry standards and OEM specifications, so it initialises identically to the original HP part and can be mixed with other OEM or third-party transceivers. Brute Networks backs the part with a lifetime warranty.

Questions about this item

How do I install the SFP module and which step is often missed?

Insert the transceiver into an SFP slot until it clicks, then connect an LC duplex single-mode patch cord; the step often missed is removing the dust caps from both the module and the cable ends before linking them.

What maintenance or replacement will this transceiver need over time?

No scheduled maintenance is required; if the link degrades, clean the LC connector ferrules with a fibre cleaning pen and re-test — replacement is only needed if the laser or receiver fails.

What is the first limit reached during sustained high-load operation?

The commercial temperature ceiling of 70 °C is the first hard limit; if the chassis airflow cannot keep the module below that, the transceiver will throttle or shut down to protect itself.
