3 ． The specifications, quantities, route directions and laying position of the cables
to be laid should meet the design requirements of construction drawings. The
laying length of each cable should be determined according to its actual position.
4
．
No intermediate break or joint is allowed for the cables to be laid.
5
．
User’s cables and power cable should be laid separately.
6
．
Inside walkways, the cables should be properly arranged in good order, with
uniform, smooth and flat turnings.
7
．
Cables should be straightly laid in cable channels. Extruding of cable from cable
channels to block other outlet or inlet holes is not allowed. The cables at the
outlet part of cable channel or at turnings should be bundled and fixed.
8
．
If cables, power line and grounding conductor are laid in the same channel,
cables, power line and grounding conductor should be not folded or blended
together. If a cable line is overly long, coil and place it in the middle of the
cabling rack, do not let it cover on other cables.
9 ． When laying the pigtail, avoid knotting of optical fiber cable, minimize the
amount of turnings and avoid turnings with overly small radius. Bundle pigtails
in proper tightness and avoid too tightly bundling. If laid on a cabling rack, it
should be placed separately from other cables.
10
．
There must be the relevant marks at both ends of cable and the information on
the marks should be explicit to facilitate maintenance.
Attention:
When laying pigtails, prevent optical fiber cable from knotting, minimize the amount
of turnings and avoid turnings with too small radius, because turning with too small
radius will result in serious consumption of optical signal of links, affecting
communication quality.
