Figure 1-6 Front panel of short-haul dual-port 10 GE CX4 interface module
A short-haul dual-port 10 GE CX4 interface module provides two 10 Gbps electrical ports and supports
CX4 electrical and protocol standards. Only 3Com’s CX4 power cables can be used for connecting the
CX4 ports. A CX4 cable is hot swappable and its maximum transmission distance is 3 m (9.84 ft.), which
is suitable for short-distance connections only.
