3.4 Connect Cables
WARNING:
Ensure the antenna is connected before powering up the eNB. The wireless
signal transmission power can cause bodily injury and damage to the eNB and Radio
Frequency (RF) power amplifier devices.
3.4.1 Cable Laying Requirements
General requirements:
Bending radius of antenna feeder cable:
−
7/8 in > 9.84 in (22.2 mm > 250 mm)
−
4/5 in > 14.96 in (20.3 mm > 380 mm)
Bending radius of jumper cable:
−
1/4 in > 1.38 in (6.3 mm > 35 mm)
−
Super soft 1/2 in > 1.97 in (13 mm > 50 mm)
−
Ordinary 1/2 in > 5 in (13 mm > 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 type of cable; intertwining and crossing are forbidden.
An identification label should be attached after the cable has been laid.
Optical fiber cable requirements:
Avoid circling and twisting of 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 laying requirements:
The grounding cable must connect to the grounding point.
The grounding cable must be separated from the signal cables, of enough distance to avoid
signal interference.
3.4.2 Connect GPS Antenna Cable
WARNING:
Ensure the antenna is connected before powering up the eNB. The wireless
signal transmission power can cause bodily injury and damage to the eNB and RF power
amplifier devices.
1.
Insert the GPS jumper into a cold shrink tube.
2.
Connect one end of the GPS jumper to the GPS antenna.
3.
Push the cold shrink tube to the top joint, and pull out the strip.
