Scope
The feeder cable connectors comply with corresponding
11 General
standards and are correctly connected, without looseness.
The feeder cables, power splitter, coupler, and surge
12 General protective devices are connected correctly and reliably in
accordance with specifications.
Strong current and weak current cables are routed separately.
The power cables, ground cables, and signal cables are
13 General bundled and routed separately (with a spacing of more than
30 mm) to prevent electrical or magnetic interference. Use
shielded cables in places with strong interference.
When routing cables in walls, place the cables in the cable
troughs or pipes and fix the cables using pipe straps. For non-
14 General
metal corrugated pipes, the fixing distance should be about
1000 mm.
All outdoor connectors or feeder cable connectors are
properly sealed to prevent water. Wrap the cable using one-
Outdoor layer PVC insulation tape, three-layer waterproof tape, and
15
AP then three-layer PVC insulation tape. The tape shall be
attached evenly and neatly. The network cables shall be
covered with waterproof PG tubes.
Cable connectors are secured on cables and sealed to prevent
water intrusion. The outlets of cable conduits on a wall are
Outdoor
16 sealed by waterproof and flame-retardant materials. Drip
AP
loops meeting the minimum bending radius requirement are
made on the network cable segment that stretches indoor.
Outdoor
17 Do not deploy cables overhead between two buildings.
AP
Waterproof labels (providing device names and cable
directions) are filled and attached to signal cables correctly.
18 General
Each label is attached 20 mm to 100 mm from the
corresponding cable connector.
Surge protection measures are taken in the places where the
Outdoor outdoor APs are installed. The outdoor APs, antennas, and
19
AP signal cables are deployed within 45-degree protection area
of a lightning rod.
The bare wires of network and feeder cables should be
Outdoor covered by the winding pipes, flexible metal conduit, PVC
20
AP pipes, or galvanization pipes. The cable outlet and inlet are
sealed to prevent dusts.
