1. A method for data transmission in an optical network between an optical line terminal and a plurality of optical network units, said method comprising the steps:
(a) providing at least one main wavelength; and (b) processing a subcarrier modulation for the at least one main wavelength, and suppressing a portion of the subcarrier modulated signal; wherein the at least one main wavelength is provided by a local oscillator; and wherein said local oscillator is a shared local oscillator that supplies a signal to each of said optical network units.
