3.5.1 Cable Connection between the DU and the RRH-2WB
The RRH-2WB is a unified RF module interfacing remotely with the DU through an
optical cable. It is located at the front end of the antenna.
Cable connection between the DU and the RRH-2WB is as shown below.
1) Install an optic cable from the DU to the optic port at the bottom of the RRH-2WB.
2) Fit a cut heat shrink tube to the optic cable before connecting the cable to the system
optic port.
3) Connect the optic cable connector (ODC type) to the optic port at the bottom of the
system.
4) When the cable connection is completed, contract the heat shrink tube (jelly type)
using a heating gun so that the flexible pipes and the connector unit are well fixed.
(Finish using silicon if necessary.)
