Installing Optical Fibers
NOTE
Inner pipe
Outer pipe
CAUTION
Wrap both ends of the corrugated pipe using tapes to prevent optical fibers from being cut.
Do not use an open-end corrugated pipe to
hold excessive optical fibers. It is
recommended that an open-end
corrugated pipe that has a diameter of 32
mm accommodates 60 optical fibers at
most, each with a diameter of 2 mm.
Ensure that about 10 cm of the open-end
corrugated pipe is inside the cabinet.
