LEDs meaning
• 1 RF antenna port, transmitting/receiving signals to/from
distributed antennas. This RF antenna port is a duplexed
N-female connectors. The port can be connected to the
antenna either directly (ie. through RF jumper cables) or
through splitters, thus allowing more antennas to be fed.
• 1 RF auxiliary input and 1 RF auxiliary output (designed to
receive and transmit additional signals). Auxiliary input
and output ports are SMA-female connectors.
• 1 optical output port, transmitting UL signals to TFLN
master optical TRX;
• 1 optical input port, receiving DL signals from TFLN
master optical TRX.
