6 Optical bers are led into a cabinet through
a corrugated pipe. The corrugated pipe
should be no longer than 100 mm and be
bundled on the cabinet.
Observe and
measure
7 The bend radius of optical bers is 20 times
larger than their diameters. Generally, the
bend radius of optical bers should be no
less than 40 mm. The path of optical bers is
not blocked by any components.
Observe and
measure
8 Optical bers are bundled by binding tape
with appropriate force.
Observe
9 Each signal cable has correct, clear, and tidy
labels attached on both ends.
Observe
10 The routes of power cables and ground
cables conform to the engineering design
document, facilitating future maintenance
and system expansion.
Observe
11 All power cables and ground cables are
complete copper wires without splices.
Coatings of power cables and ground cables
are intact.
Observe
12 Power cables and ground cables are
connected properly.
Observe
13 Power cables and ground cables are routed
in compliance with the engineering design
document, meeting power distribution
requirements.
