1. A method for optical layer traffic grooming comprising the steps of:

  • receiving at least two optical input signals into respective optical receivers, each said optical receiver having a photodetector for converting the respective optical input signal into a respective electrical signal;

    a grooming processor responsive to said electrical signals, said grooming processor being a radio frequency RF processor for processing the electrical signals at a subcarrier level to produce an RF orthogonal frequency division multiplexing signal OFDM signal; and

    modulating the groomed RF OFDM signal at a transmitter for conversion of the groomed RF OFDM into an optical signal.
