3.4 Connect Cables
WARNING:
Ensure the antenna is connected before powering up the gNB. The wireless signal
transmission power can cause bodily injury and damage to the gNB and RF power amplifier
devices.
3.4.1 Cable Laying Requirements
General requirements:
•
Bending radius of antenna feeder cable:
−
7/8" > 250 mm
−
4/5" > 380 mm
•
Bending radius of jumper cable:
−
1/4" > 35 mm
−
(Super soft) 1/2" > 50 mm
−
(Ordinary) 1/2" > 127 mm
•
Bending radius of power cable and grounding cable: > triple the diameter of the cable.
•
The minimum bend radius of the optical fiber is 20 times the diameter of the optical fiber.
•
Bind the cables according to the cable type; intertwining and crossing are forbidden.
•
An identification label should be attached after the cable is laid.
Optical fiber cable requirements:
•
Avoid circling and twisting cables while laying the cable.
•
Avoid binding or kinking of cables on a turn.
•
Avoid pulling or weighing down the optical fiber cable.
•
The redundant optical fiber must wind around the dedicated device.
Grounding cable requirements:
•
The grounding cable must connect to the grounding point.
•
The grounding cable must be separated from the signal cables to avoid signal interference.
3.4.2 Connect GPS Antenna Cable
WARNING:
Ensure the antenna is connected before powering up the gNB. The wireless signal
transmission power can cause bodily injury and damage to the gNB and RF power amplifier
devices.
The GPS antenna should be installed in an open, lightning-protected position. The top of the GPS antenna
should avoid facing the front of the directional antenna and should be installed as far away as possible
from the directional antenna.
1. Insert the GPS jumper into a cold shrink tube.
2. Connect one end of the GPS jumper to the GPS antenna interface and tighten it.
3. Push the cold shrink tube to the top joint and pull out the strip.
