The bending radius of a single-mode G.657A2 optical fiber is no less
than 10 mm, and that of a multi-mode A1b optical fiber is no less
than 30 mm.
After laying out optical fibers, use binding straps to bind the fibers
neatly without squeezing them.
After the optical fibers are connected, the optical ports and optical
connectors that are not used must be covered by dustproof plugs and
dustproof caps, respectively.
Do not use an open-end corrugated pipe to hold excessive optical
fibers. It is recommended that an open-end corrugated pipe with a
diameter of 32 mm accommodate a maximum of 60 fibers with a
diameter of 2 mm.
It is recommended that the length of a corrugated pipe inside a cabi-
net be about 100 mm.
NOTE
Installing Optical Fibers
When performing operations such as installing or maintaining optical
fibers, do not move your eyes close to or look into the optical fiber
outlet without eye protection.
WARNING
CAUTION
Before routing internal optical fibers, install fixed optical attenuators
at the corresponding optical ports on devices according to the fixed
optical attenuator installation table.
