Figure 6-6 Hoisting the fiber optic cables onto a tower

1. Lifting sling

2. Fixed pulley

3. Traction sling

Before hoisting fiber optic cables onto the tower, connect the fiber optic cables to the remote

radio unit (RRU) or baseband unit (BBU) based on the labels on both ends of the cables and

determine the hoisting direction.

1. Technician A climbs the tower, secures a fixed pulley to the support on the tower

platform, and then routes the lifting sling through the fixed pulley.

2. Technician B places the fiber coiler for coiling fiber optic cables on the fiber spools, and

technician D leads the lifting sling through the stretch sling of the fiber optic cables and

use the other sling as a traction sling to secure the cables 4 m (13.12 ft) away from the

lifting sling, as shown in Figure 6-7.
