Baseband ofdm optical single-sideband transmission with parallel optical SSB modulation for direct detection

Abstract

A novel baseband OFDM optical SSB transmission scheme using parallel optical SSB modulation is proposed for long-haul optical transmission. Since the proposed scheme adopts the traditional SSB modulation theory and only uses the even sub-carriers to transmit data, simulations show that it has higher tolerance to the signal-signal beat interference and the nonlinearity effects comparing to the known baseband direct detection OFDM schemes.
