Installing Fibers
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.

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.
For a closed corrugated pipe, take protective measures and then route fibers into the corrugated pipe. For an open
corrugated pipe, route fibers into the corrugated pipe and then take protective measures.
After routing fibers into 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 ( 0.079 in ) diameter fibers in an open corrugated pipe and not more than twenty 2 mm ( 0.079 in ) diameter
fibers in a closed corrugated pipe (See Figure 3).
The corrugated pipe needs to be routed into the cabinet for approximately 10 cm ( 4 in ) (See Figure 4).
