Optical fibers cannot be stretched with too much force or stepped on, and they are far
away from sharp objects. Heavy objects cannot be placed on optical cables.
When optical cables are routed, the extra length of the cables is coiled around special
devices, such as a fiber coiler.
Even strength is applied when optical cables are coiled and optical cables cannot be bent
in a forcible manner.
Vacant optical connectors are covered with dust-proof caps.
Fiber optic cables cannot be squeezed by the cabinet door when routed through the
cabinet.
If optical cables need to be routed on the tower platform, the optical cables are routed
along the inner side of the guard rail and the distance between the guard rail and the
cable is the shortest one.
If optical cables need to be routed close to a device on the tower, the optical cables are
secured to the guard rail or pole with cable clips and the device cannot be far away from
the position for securing the optical cables.
If the optical cable close to a device on the tower is too long, the optical cables are
wrapped and secured to the tower.
Except the CPRI fiber optic cable, for details about the cables exterior and related description in Table
6-3 and Table 6-4, see 3900 Series Base Station Cables.
