Steps
5The outdoor optical fiber should be laid vertically at least 200 mm from
the lower edge of the device when it is led out from the bottom of the RRU
chassis. The optical fiber should not be bent. If the outdoor optical fiber
is too long, the excess part should not be reserved in the equipment room
but at the FIRU side instead. Coil the excess part of the optical fiber in a
diameter of 300 mm to 400 mm and then bind the fiber coil to the pole
with black cable ties.
1Clean the sundries like dust and stain on the cable
connector.
2Wrap a layer of electric insulation tape, as shown
in Figure 1.
After installing the cable connector, apply another
layer of insulation tape from the top down. The
upper—layer insulation tape covers 1/2 of the lower—
layer insulation tape.

3Take waterproof measures for interfaces.
Install the shrink sleeve. For the installation
of the shrink sleeve, refer to the DIN Shrink
Sleeve Engineering Installation Specifications.
4Connect the other end of the feeder to the ANT
interface on the antenna. Take waterproof measures.
5The feeder should be laid vertically at least 200 mm from the lower edge
of the device when it is led out from the bottom of the RRU chassis. It
should not be bent. Coil the excess part of the feeder into the "S" or "8"
shape, and then bind the coil on both sides of the pole or on the back
(N-type connector) of the RRU chassis. The minimum bending radius of
the feeder should not be less than 20 times the feeder's radius. It is
prohibited to coil the feeder.
