1. A node for a communications network, comprising:
a receiver having a plurality of receiver outputs, wherein the receiver is configured to receive from the communications network a first modulated optical signal, comprising a received first plurality of optical subcarriers, and to supply a plurality of data streams, each of the plurality of data streams being a respective data stream detected by the receiver from a corresponding one of the received first plurality of optical subcarriers, and each of the plurality of receiver outputs supplying a respective one of the plurality of data streams;
a switch circuit having a plurality of switch inputs and a plurality of switch outputs, wherein each of the plurality of switch inputs is communicatively coupled to the receiver and configured to receive a respective one of the plurality of data streams supplied by the plurality of receiver outputs, and wherein each of the plurality of switch outputs is configured to supply a respective one of the plurality of data streams received at the plurality of switch inputs; and
a transmitter having a plurality of transmitter inputs, wherein each of the plurality of transmitter inputs is communicatively coupled to a corresponding one of the plurality of switch outputs and is configured to receive a corresponding one of the plurality of data streams supplied by the plurality of switch outputs,
wherein the transmitter is configured to supply to the communications network a second modulated optical signal based on the plurality of data streams received at the plurality of transmitter inputs, the second modulated optical signal carrying a second plurality of optical subcarriers, each of the second plurality of optical subcarriers being associated with a corresponding one of the plurality of data streams received at the plurality of transmitter inputs.
