Precautions
1
Avoid direct eye exposure to fiber connectors when performing operations such as installing and maintaining fibers.
2
The bending radius of G.657B3 fibers must not be less than 8 mm, consult the Installation Reference for the
bending radius.
3
After installing fibers, insert a fiber plug into each unconnected optical port and cap the unused connector on each
fiber patch cord.
4
When routing and installing fibers onsite, you need to clean fiber end faces.

Open-End Corrugated Pipe Introduction
•Do not use an open-end corrugated pipe to hold excessive fibers. It is recommended that an open-end
corrugated pipe that has a diameter of 32 mm accommodate 60 fibers at most, each with a diameter of 2
mm.
•Before routing fibers out of a cabinet, ensure that they are protected in an open-end corrugated pipe and
about 10 cm of the open-end corrugated pipe is inside the cabinet.
•When an A63B cabinet uses corrugated pipes to protect optical fibers, 360 optical fibers can be routed on
one side at the top of the cabinet, and a total of 720 optical fibers can be routed.
NOTE
Optical fiber protection using corrugated pipes
•When an A63B cabinet uses winding pipes to protect
optical fibers, 720 optical fibers can be routed on one side
at the top of the cabinet, and a total of 1440 optical fibers
can be routed.
