3.5.8 Optical Fibers
Optical fibers can be prepared on site. The following table lists the type of cables and mating connectors
needed to prepare cables for each NPT-1020 module.
For each optical interface, ECI supplies patch cords with mating optical connectors already attached to the
fiber. Therefore, only the optical termination on the ODF side, which is installation-dependent, must be
installed on site.
The optical fibers for connecting to equipment installed in a given rack must enter the rack from the top, be
threaded through cable guides running along the rack side rails, and end at the FST. The FST must contain
enough fiber length for extracting modules from the NPT-1020 and for replacing fiber in case of damage
(splicing repairs).
When routing fibers, make sure to observe the minimum bending radius (35 mm).
