Principle of the Proposed Optical Modulation Technique Having Adaptable Spectral Efficiency

Caption

This is about the principle of the proposed optical modulation technique having adaptable spectral efficiency. The table lists the modulation formats used in the experiment for time slots 1 and 2, as well as the modulation formats' spectral widths and the resulting range of adaptable spectral width attainable for the TDM frame from the proposed optical modulation technique. TDM: time-division-multiplexed; PM: polarization-multiplexed; QPSK: quadrature phase shift keying; QAM: quadrature amplitude modulation.
