For each port, TX signals and RX signals are separated from
terminate unused ports unless you want to.
BIU interface with Base station Transceiver
Basically, BIU has different TX and RX ports, and so, you have only to connect input
and output ports.
Through spectrum, you need to

20dBm~+10dBm), you can connect an attenuator ahead of the input port
to put the signals in the input range.
BIU interface with Bi-

Basically, BIU is in Simplexer typ

Using a duplexer or a circulator, you can separate TX/RX signals of an external device
from each other.
