HP ProCurve 10GbE X2-CX4 Transceiver

The HP ProCurve J8440A is a 10 Gbit/s CX4 transceiver designed for high-speed data networking links. It provides a single CX4 interface supporting 10GBase-CX4 connectivity over copper cabling. This module suits network administrators upgrading rack-mounted switches or servers to 10 Gigabit Ethernet within short distances.

Direct-attach copper replacement for optical modules

The transceiver replaces optical transceivers when the link distance stays within 49.21 ft, removing the need for fibre patch cords and separate optics. The jump is worth it for top-of-rack or adjacent-rack connections where copper reach is sufficient and lower latency per hop matters. It is not for links exceeding the supported reach or for SFP+ only ports.
