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

Figure 1.1 The mechanical specifications of the DCM frame.

7.3.2 Installing the DCM and DCM Frame

Purpose This procedure describes how to fix the DCM on the frame

and install the frame in the cabinet.

Tools /Materials Cross screwdriver

Prerequisites The cabinet and the subrack are installed.

Required/As needed As needed

Step 1 Put DCMs on the frame and fix them with screws from below Each DCM needs

four screws See Figure 1.1

DCM frame Mounting bracket

Screw

Figure 1.1 Installing DCM on the DCM frame

 Note

If only one DCM is to be installed in the cabinet, it is fixed on the left of the DCM frame so as to facilitate the distribution of optical fibers on the left

Step 2 Fix the DCM frame on the columns of the cabinet with panel fastener

7.3.3 Routing Optical Fibers for DCM

Purpose This procedure describes how to route optical fibers for

DCM.

Tools /Materials None

Prerequisites The cabinet and the subrack are installed.

Required/As needed Required

Step 1 Lead the optical fibers out from the subrack

Step 2 Run the optical fibers downward along the fiber trough at the cabinet side to the

cabinet bottom

Step 3 Pass the optical fibers through the inlet at the side of the DCM frame

Step 4 Connect the optical fibers to the fiber connector of the corresponding DCM
