Copper, not fiber, is the medium for the X2-10GB-CX4, a Cisco 10GBASE-CX4 X2 module with an InfiniBand 4x connector. It supports link lengths of up to 15 m (49.2 ft) on CX4 cable and follows IEEE 802.3ak. As a copper module it has no optical transmit or receive power figures.
Cisco sells four matching CX4 cables: CAB-INF-28G-1= at 1 m, CAB-INF-28G-5= at 5 m, CAB-INF-28G-10= at 10 m and CAB-INF-26G-15= at 15 m. The module is hot-swappable, measures 91 mm x 36 mm x 13.46 mm (D x W x H), typically weighs under 300 grams and uses at most 4 W. The Cisco quality ID feature lets the host switch or router confirm the module is certified and tested by Cisco.
X2 transceivers are required on the WS-X6708-10GE and WS-X6716-10GE 10 Gigabit Ethernet modules, and the CX4 type carries no restrictions there. The Catalyst 4948-10GE also accepts it among its supported X2 optics. For a fiber link on the same ports, the X2-10GB-SR covers 26 to 400 m of multimode fiber, and more modules are in the Cisco interface card category.
