•When routing fibers outside the cabinet, use a bellow or wound tube. The bellow should be routed to the
cabinet by about 10 cm and should also be bound.
•Cut the bellow to a proper length according to cabling distance from the chassis to the ODF.
•After routing fibers into the bellow, use a strap to bind the cut of the bellow.
•When routing fibers through the cable guiding frame, make sure that the fibers are not pressed by other
cables. Otherwise, the fibers may be damaged.
•When routing fibers, make sure that the bending radius of the fibers exceeds the minimum curvature radius.
The minimum curvature radius of a 2 mm fiber is 40 mm.
•As the Ethernet service interfaces support the adaptive function, the network cable can be either crossover cable
or straight-through cable. The straight-through cable is recommended.
•If the equipment needs to install telephone wires, install them after installing the Ethernet service cable. The
installation is similar.

Laser
When handling optical fibers, do not stand close to or look into the optical fiber outlet directly with
naked eyes.
