7.3 Installing the DCM
This section describes the installation of DCM and DCM frame as well as the
routing of optical fiber for DCM.
7.3.1 Overview of DCM and DCM Frame
DCM
The DCM is used to compensate dispersion for optical signals. Each DCM has
two fiber connectors to receive and send optical signals, which are connected to
the optical interface of the corresponding board through optical fibers.
DCM frame
The DCM frame is used to hold the dispersion compensation module (DCM), and
one DCM frame can hold up to two DCMs. Before installing the DCM frame, it is
required to fix the DCM to the frame. In delivery, the screws for installing the
DCM are usually bound to the columns of the cabinet.
Figure 1.1 shows the mechanical specifications of the DCM frame.
