1. A system comprising:

  • a first communication device configured to convert an optically-modulated source signal to a radio signal based on a detected degradation in a quality of a received optical signal, the first communication device comprising an optical signal splitter that splits said optically-modulated source signal into first and second optical signals, said first optical signal being coupled to an optical transceiver, and said second optical signal being coupled to an optical-to-electrical converter coupled to a radio transceiver; and

    a second communication device configured to convert a radio-modulated source signal to an optical signal based on a detected degradation in a quality of a received radio signal;

    further comprising a control system configured to detect said degradation in said received optical and radio signals by comparing a respective received signal with a reference value;

    wherein said first communication device further comprises first and second optical switches controlled by said control system, said first optical switch being connected between said optical signal splitter and said optical transceiver for switching said first optical signal, and said second optical switch being connected between said optical signal splitter and said optical-to electrical converter for switching said second optical signal.
