1. An apparatus for multiplexing with variable grades of service to independent channels, the apparatus comprising:

  • first and second lasers;

    first and second digital data signals;

    first and second photonic modulators configured to modulate the first and second lasers with the first and second digital data signals, providing first and second modulated photonic signals;

    first and second delay mechanisms configured to provide delayed copies of the first and second modulated photonic signals, delayed by first and second delays, respectively;

    combiners configured to combine the delayed copies with the first and second modulated signals to form first and second consolidated modulated signals, respectively; and

    a control module configured to adjust the power of the first and second consolidated signals by first and second weights, respectively, corresponding to the quality of service required by first and second users.
