HP JD089B Hewlett-Packard HP / HPE / Aruba enterprise networking and server portfolio Optical Transmission Module

The HP JD089B is an X120 1G SFP RJ-45 T transceiver. Unlike the optical modules in the same family it terminates copper: a 1000BASE-T Gigabit link on a standard RJ-45 connector, giving an SFP cage the ability to take a normal patch lead over the usual 100 m structured cabling limit. It is commonly used where a switch has run out of fixed copper ports but still has SFP slots free, or where a device needs a copper handoff from an otherwise fibre uplink.

Transceivers are the pluggable optics that decide the reach and media of a switch or router port, and HP sold them under the X120, X130 and X132 names across the SFP, SFP+ and later form factors. Reach and wavelength vary by model, from short range multimode inside a building to extended reach single mode across a metro span, and copper SFPs cover short RJ-45 runs. HP switches check the vendor code on the module, so matching the exact J-number matters.
