You can lay out op ptical fibers as required by observing the following principles:
a. Lead the corru ugated pipe to the routing hole for the signal cable at the top of
the cabinet an d fix the pipe.
b. b. Lay out the op Lay out the op ptical fiber along the optical fiber path on the cabinet and lead it ptical fiber along the optical fiber path on the cabinet and lead it
to the interface e area through the corresponding routing trough.
If there is no routin g trough, you can lead the optical fiber leftward or rightward
after putting the op ptical fiber horizontally with the interface, and then insert the
optical fiber into the e optical interface, without obstructing other interfaces, as
shown in the left fig gure.
The number of optic cal fibers should be less than 60 (in an open corrugated pipe)
or 25 (in a closed corr rugated pipe).
Do not bundle the o optical fibers too tightly. Otherwise, the quality of the
communication betwe een devices is reduced.
The minimum bend d radius of the turnings of optical fibers should be larger than 4
cm.
When laying out an nd connecting optical fibers, note the difference between a
single-mode one and a multi-mode one.
