 Avoid pulling and weighing down the optical fiber.
 The redundant optical fiber must enwind the dedicated device.
Grounding laying requirements:
 The grounding cable must connect to the grounding point.
 The grounding cable must be separate with the signal cables, of enough distance to
avoid signal interference.
3.5.2 Connect GPS Antenna
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.
4. Take another cold shrink tube, and pass through the GPS jumper.
5. Connect the other end of the GPS jumper to GPS interface on the eNB.
6. Push the cold shrink tube to the GPS port, and pull out the strip.
3.5.3 Connect RF Cable
1. Open the dust caps of the ANT0, ANT1, ANT2, and ANT3interfaces.
2. Insert RF cables into cold shrink tubes.
3. Connect RF cables to the ANT0, ANT1, ANT2, and ANT3 interfaces on the eNB,
and tighten them with wrench to 12-15 in-lbs or 1.4-1.7 NM torque.
4. Push the cold shrink tube to the top joint and pull out the strip.
5. Take another cold shrink tubes, and pass through the RF cables.

3.5.4 Connect Optical Fiber
1. Unscrew the 3 screws on the cover of the eNB’s wiring cavity using M4 cross
screwdriver. Open the wiring cavity.
2. Connect the optical fiber to OPT interface in the wiring cavity.
3. Lay the optical fiber along the wire groove, and stretch out the wiring cavity from
OPT hole.
