Installing the Enhanced Digital Reverse Modules in the Node
2-17
Serial Data Connection
Overview
The following procedures detail how to interconnect the modules to the node.
Perform these procedures with the housing open, the optional status monitor
module removed, and the fiber management tray unstowed.
Serial Data Interconnection
Follow these steps to make the serial data interconnection.
1.
Double-wide Laser Module:
Connect one end of the semi-rigid coax cable to the Serial Data Output
Primary connection on the 2:1 enhanced multiplexing digital module.
Terminate the redundant serial data output connection.
Single-wide Laser Module:
The 16” semi-rigid coax cable is not used to connect the single-wide laser
module to the 2:1 enhanced multiplexing digital module. One end of a semi-
rigid coax cable is permanently attached to the single-wide laser module.
Connect the other end of this cable to the Serial Data Output Primary
connection on the 2:1 enhanced multiplexing digital module. Terminate the
redundant serial data output connection.
Note: If you’re using two laser modules, connect both the Redundant and
Primary data output ports.
2.
Route the semi-rigid coax cable along the side of the 2:1 enhanced
multiplexing digital module, away from the housing lid hinges and around
the fiber tray bracket to the Serial Data Input on the laser module (double-
wide laser module only).
Note: There is ample space by the side of the 2:1 enhanced multiplexing
digital module to store the extra length of cable.
