7.5.4 Cable Connections (Outdoor)

This section describes the cable connections for a pRRU3901 installed outside.
Before installing the pRRU3901 cables, you must be aware of the following information:

 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.

When two Ethernet cables are used to transmit CPRI signals, connect one end of the cables to the
CPRI_E0 and CPRI_E1 ports on the pRRU panel and the other end to any two ports of CPRI_E0 to
CPRI_E7 on the RHUB panel. On the RHUB panel, CPRI_E0 and CPRI_E1, CPRI_E2 and
CPRI_E3, CPRI_E4 and CPRI_E5, and CPRI_E6 and CPRI_E7 are used in pairs. CPRI_E0 on the
pRRU panel connects to the even-numbered CPRI port (for example, CPRI_E0, CPRI_E2, CPRI_E4,
or CPRI_E6) on the RHUB panel, and CPRI_E1 on the pRRU panel connects to the odd-numbered
CPRI port (for example, CPRI_E1, CPRI_E3, CPRI_E5, or CPRI_E7). This document describes
signal transmission using one Ethernet cable as an example.
The pRRU3901 can obtain power supply through the power over Ethernet (PoE).
For external antennas corresponding to RF daughter board 1, the TX port and RX port
are ANT0 and ANT1, respectively. For external antennas corresponding to RF daughter
board 2, the TX port and RX port are ANT2 and ANT3, respectively. For external
antennas corresponding to RF daughter board 3, the TX port and RX port are ANT4 and
ANT5, respectively.
The external antenna system is optional, and the pRRU3901 jumpers are not delivered.
By default, the pRRU3901s are configured with built-in antennas. If the external antenna
system is connected, the antenna system automatically switches to the external one. One
end of the pRRU3901 RF jumper is the SMA male connector, which is connected to the
