Installing Fibers Within and Outside a Cabinet
a
Installing Fibers for Chassis
When installing or maintaining fibers, do not look into optical ports without eye protection.
Before installing and routing fibers within a cabinet, install FOAs on optical ports according to the FOA installation list.
When the recommended A63B cabinet is adopted, you are advised to add only one optical attenuator. If multiple
optical attenuators are added, the cabinet door may fail to be closed.
The bending radius of a single-mode G.657A2 optical fiber is greater than or equal to 10 mm, and the bending radius
of a multi-mode A1b optical fiber is greater than or equal to 30 mm. Ensure that optical fibers are bound properly by
fiber binding tapes and not squeezed after they are laid out. After the optical fibers are connected, the optical
connectors and optical ports that are not used must be covered by dustproof plugs and dustproof caps respectively.

1
For fibers with labels indicating that they are from
optical ports on the board, put them on the same side.
2
Install optical modules.
3
Bind fibers from the same row into a bundle,
route bundles through a cable management
frame, and install the fibers.
4
Coil extra fibers and hang or fix them on the
left side of the cabinet.
If it is difficult to install and remove the cables, use a
fiber extractor.
