When connecting fibers between the front side and rear side of a cabinet, route fibers through the
bottom of the OptiX OSN 8800 T64 subrack inside the cabinet. In this case, the fibers must be
protected in winding pipes at throughholes. See the figure below.
CAUTION
The figure below shows the paths for
routing front- and rear-side fibers of
the T64 subrack.

Cable-routing area for
internal fibers
Take priority to use 2 m fibers for cascading subracks inside a cabinet. The internally cascaded fibers must be separate from
the external fibers. The external fibers should be routed through the cable-routing area on the rear of the cabinet, and the
internally cascaded fibers should be routed through the cable-routing area on the front of the cabinet. When there are too
many internally cascaded fibers to be routed through the cable-routing area on the front, the remaining fibers can be routed
through the cable-routing area on the rear of the cabinet. Ensure that these cascaded cables are not intertwisted with the
external fibers.
