Central Location ED -1E434, Group 461 or 463 RMI Fiber Link(s)(Phase 2)
Install the RMI fiber link(s) for the central location from the RMI carriers to the central
LCIT.
WARNING: The cable must be loosely supported to prevent damage. The
fiber-optic cable has a minimum bend radius of 1.5 inches.
Figures 50 and 51 show the RMI fiber link, and Tables Z and AA show the appropriate
backplane connectors used for an unduplicated and duplicated system at the central location.
Install the RMI fiber link(s) as follows:
1. Connect transmitter (Z982J) and receiver (Z982D) paddleboards to A00-A30 even and
A01-A31 odd on the backplane of the RMI carriers. The transmitter paddleboard must
be mounted first.
2. Connect transmitter paddleboard Z982J to Fiberl/Blue and the receiver paddleboard
Z982D to Fiber2/White of the ED-1E434, Group 461 or 463 lightguide cable.
3. Route the cable out of the TMS/RMI cabinet to the central LCIT outside the overhead
dpcts using the locally provided hardware. This cable should enter the right side of the
LCIT. Figure 47 illustrates the routing of lightguide cables.
4. Connect the appropriate attenuator to the central LCIT (Figure 46) in the correct
position as determined by your CSD.
5. Connect the fiber-optic cables to the appropriate attenuator as shown in Figures 50 and
51.
