HP X140 40GBase-SR4 Transceiver

The HP X140 is a QSFP+ transceiver module designed for 40 Gbps connectivity over multi-mode fibre. It suits network engineers and data-centre operators who need reliable short-range links between switches, routers or servers within the same rack or row.

40 Gbps Multi-Mode Fibre Integration

This module plugs into a standard QSFP+ cage and operates at 850 nm wavelength to reach up to 100 m over OM3 or OM4 multi-mode fibre. It frees up copper uplink ports and reduces cable bulk in dense patching environments while drawing power directly from the host port.

Upgrade from 10 Gbps or Copper Uplinks

Replacing four separate 10 Gbps SFP+ links or copper direct-attach cables with a single 40 Gbps QSFP+ link simplifies cabling and cuts port consumption. The jump is worth it when bandwidth demand exceeds 10 Gbps per lane and the link distance stays within 100 m.
