Installing Fibers
a
Precautions
CAUTION
When installing or maintaining fibers, do not look into the optical port without eye protection. See Figure 1.
Coil up the inter-office fibers on the ODF and then route them into the cabinet. Do not coil up external fibers
in the cabinet.
NOTE
When routing fibers, take proper measures to avoid any damage to fiber connectors
After installation of the fibers, place protective caps on to the idle optical ports, and place fiber caps on to the
idle fibers. See Figure 2.
Figure 1
NOTE
For a closed corrugated pipe, take protective measures and then route fibers into through corrugated pipe. For
an open corrugated pipe, route fibers through the corrugated pipe and then take protective measures.
After routing fibers through a corrugated pipe, wrap PVC insulation tapes around the cuts of the corrugated pipe.
Do not feed a large number of fibers in a corrugated pipe. It is recommended that you feed not more than sixty
2 mm diameter fibers in an open corrugated pipe and not more than twenty 2 mm diameter fibers in a closed
corrugated pipe (See Figure 3).
The corrugated pipe needs to be routed into the cabinet for approximately 10 cm (See Figure 4).
