Central Location ED -1E434, Group 461 or 463 RMI Fiber Link(s)(Phase 1)
Install the RMI fiber link(s) for the central location from the module control(s) 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 48 and 49 show the RMI fiber link 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 A05 and A04 on the
backplane of the module control carriers. The transmitter paddleboard must be
mounted first.
2. Connect transmitter paddleboard Z9821 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 module control cabinet to the central LCIT outside the
overhead ducts 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 48 and
49.
