DCM Frame and DCM Module
The DCM frame can be used to hold DCM modules which compensate the positive dispersion of transmitting fiber, so as to maintain the original shape of the signal pulse. If your network needs this equipment, contact Huawei.DCM Frame
The DCM frame is fixed onto the columns of the cabinet by mounting brackets and screws, as shown in Figure 8-1 and Figure 8-2.

DCM Module
After an optical signal is transmitted over certain distance, the optical signal pulse is widened because of the positive dispersion accumulated in the system. This widened shape seriously affects the system transmission performance. The DCM is a passive device that uses a dispersion compensation fiber. Because a DCM has inherent negative dispersion that can offset the positive dispersion of transmission fibers, the signal pulses are compressed.
The OptiX OSN 1800 can provide several types of DCMs of several compensation distance specifications: 5 km (3.1 mi.), 10 km (6.2 mi.), 20 km (12.4 mi.), 40 km (24.8 mi.), 60 km (37.3 mi.), 80 km (49.7 mi.), 100 km (62.1 mi.), 120 km (74.6 mi.).
