Wireless distribution systems (wdss) employing an optical star communications architecture based on quad small form-factor pluggable (qsfp) coarse wavelength division multiplexing (cwdm) transceivers

A wireless distribution system (WDS), comprising:

• one or more remote unit branches each comprising a plurality of remote units and configured to carry a respective wavelength division multiplexing (WDM) downlink communications signal among one or more WDM downlink communications signals to the respective plurality of remote units in the remote unit branch and carry a respective WDM uplink communications signal among one or more WDM uplink communications signals from the respective plurality of remote units in the remote unit branch;
• and
• a central unit comprising one or more quad small form-factor pluggable (QSFP) coarse WDM (CWDM) transceivers communicatively coupled to the one or more remote unit branches via one or more optical fiber trunks, respectively;
• wherein a selected QSFP CWDM transceiver among the one or more QSFP CWDM transceivers is configured to:
• receive and wavelength multiplex a plurality of downlink optical communications signals to generate a WDM downlink communications signal among the one or more WDM downlink communications signals;
• provide the WDM downlink communications signal to a selected remote unit branch among the one or more remote unit branches over a selected optical fiber trunk among the one or more optical fiber trunks;
• receive a WDM uplink communications signal among the one or more WDM uplink communications signals from the selected remote unit branch via the selected optical fiber trunk;
• and
• wavelength de-multiplex the WDM uplink communications signal into a plurality of uplink optical communications signals.
