Progress on Optical Single-sideband Transmission

There are only two modulation schemes which have been commercially deployed in fiber optical communications, namely the intensity modulation (IM) and the dual-polarization Quadrature Amplitude Modulation (QAM) schemes. These two modulation schemes, however, are very different in term of spectral efficiency, implementation’s complexity, transmission performance and reliability. Compared to the IM scheme, single sideband (SSB) modulation scheme can offer enhanced transmission performance and spectral efficiency. While SSB scheme has lower spectral efficiency than dual-polarization QAM scheme, it can provide additional functionalities, lower complexity and higher reliability. Because of these unique features, SSB modulation can be a suitable modulation format for several emerging applications such as dispersion tolerant DWDM regional and access networks, data center interconnect, optical network monitoring and 5G mobile fronthaul. In this talk, we will review the recent progress of optical SSB modulation for these applications and discuss its potential for commercialization in the near future.
