1. A communication system, comprising:

  • a plurality of nodes adapted to provide for a communication with one or more devices;

    a central node;

    a passive optical network comprising a multiplexer/demultiplexer device adapted to demultiplex a first optical signal from the central node to the plurality of nodes, and to multiplex second optical signals from one or more of the nodes, each node comprising allocated a wavelength for generating its optical signal;

    wherein for directly transmitting signals from one node to at least one of the other nodes, the one node is adapted to generate an optical signal at the wavelength allocated to the at least one of the other nodes, the optical signal comprising the signal to be transmitted; and

    wherein the multiplexer/demultiplexer device of the passive optical network is adapted to combine the optical signal from the one node with the first optical signal.
