Optical transceiver module for communications in das systems

An optical transceiver module for communications in DAS (Distributed Antenna System) systems, installable on the Master Unit side of a DAS system connectable to a plurality of Remote Units, comprising:

• at least one uplink connector and at least one downlink connector connectable to at least one radio base station;
• at least a first optical connector and at least a second optical connector connectable to said Remote Units;
• at least one downlink path for the connection between said downlink connector and said first and second optical connector;
• and
• at least one uplink path for the connection between said uplink connector and said first and second optical connector,
• wherein said uplink path comprises at least a first coupler of the WDM type and at least a second coupler of the WDM type connected, respectively, to said first optical connector and to said second optical connector,
• wherein said uplink path comprises at least a first demultiplexer and a second demultiplexer connected, respectively, to the outputs of said first coupler and of said second coupler and configured for separating the optical signals coming from said Remote Units, and at least one unit for conversion and processing connected to the outputs of said first demultiplexer and of said second demultiplexer and connected to said uplink connector, configured for converting and processing said separated optical signals to obtain an RF signal to be sent to said uplink connector.
