7.5.3 Cable Connections

This section describes the cable connections for a single pRRU3901 and multiple pRRU3901s
in UMTS, LTE FDD, UMTS+LTE FDD, LTE FDD+LTE FDD mode.
Before installing the pRRU3901 cables, you must be aware of the following information:
Issue 06 (2015-10-30)
A maximum of 100 Ethernet cables can be bundled if no PVC pipes are used. If pipes are
used, a maximum of 24 Ethernet cables can be led through a pipe. In this case, ensure
that 1/3 space inside the pipes must be vacant.
The point at which an Ethernet cable is bundled must be spaced 400 mm or less from the
Ethernet port on a pRRU.
For the pRRU3901 used in the elevator engine room on the rooftop, generator set for the
subway engine, and equipment room with central air conditioning, Ethernet cables must
be led through metallic conduits that are reliably grounded at both ends.

NOTE
l The Extender can be used to lengthen the distance between the RHUB and the pRRU3901 connected
using the Ethernet cable. If the Extender is used, the Ethernet cable is divided into two parts, one
between the RHUB and the Extender and the other between the Extender and the pRRU3901.
l The Ethernet cable used for connecting the GE port on the pRRU3901 to the transmission port on
the AC is required only when the pRRU3901 have three transmission ports and is configured with
the Wi-Fi daughter board.
