ZXG10 iBSC Hardware Installation Guide
g.
When laying the cables along the vertical cabling trough, ensure that a cable clip
is used at every spacing of 100 mm.
h.
The extra parts of the cable ties should be cut off and free of burrs.
2.
Routing Methods of Internal Fiber
Different from cables, fibers are often connected to the front panel of the subrack or
the equipment. Therefore, the fiber cabling is particular. Cable the fibers outputted
from different panels along the panel respectively. The fiber cabling should not affect
the insertion and extraction of adjacent boards. Besides, there are some particular
requirements:
a.
Cable the fibers in pairs. Do not bend then in right angle. If it is obliged to bend,
the bending radius mustn’t be less than 30 mm.
b.
It is better to bind the fibers fixed on the vertical trough every 300 mm. Bundle
with fiber adhesive tapes at each distribution point.
c.
When cabling fibers in the whole equipment, make the fibers be supported. Do
not lay cables on the fibers.
d.
Do not contact the fibers with the sharp edges of the cabinet. Prevent the fibers
from being damaged. The actual gap between the cable and mechanical parts
must be greater than 10 mm. If there is no guarantee, add the jacket.
e.
Add the jacket to the fibers that is unnecessary for the time being for the protection.
Wire, bundle and fix them.
f.
If there are few fibers and when cabling the fibers with signal cables, protect the
fiber with wiring pipe. Use corrugated pipes where they leave the cabinet, to
prevent fibers from being crushed.
6.1.1.3 Cabling Requirements for External Cables
1.
Methods of Laying External Cables
a.
In the room with support and static floor installed, all cables can be routed from
in-between floor or cable trough. If routing upside, cable rack shall be paved above
the cabinet.
b.
The position to place cable shall be designed in advance, and all cables shall be
kept in order and no any damage.
c.
External cables include power cable, tail fiber, trunk cable, and other signal cables.
The cables on the cabling rack must be bundled according to category, and cables
can not be crossed. The cables are bound and fixed by cable tie, with a 20 cm
spacing between each other.
d.
Cable bends smoothly, the bending radius shall be more than 60 mm.
e.
Routed cables shall be bundled with tidy and order appearance, the cable tie shall
be evenly distributed and have suitable tension.
