BT NTE16U/7A

This NTE declares itself part of the Access SDH range, it comprises 16 2mb/s tribs multiplexed to a 34MB/s “F” type fibre connection, presumable single mode fibre. It seems to be made by Fujitsu from the markings on the PCB.

The tribs have connections for G703 on coax (BNC), G703 on 120Ohm twisted pair (RJ45) and V21 on a 15p “D” socket.

The fibre connection is a single fibre, so it must be bidirectional, presumable using wavelength division multiplexing (WDM) in each direction as per the diagram.

This is the PCB mounted fibre transceiver:-
