MULTI-CARRIER DIFFERENTIAL PHASE SHIFT KEYING BASED OPTICAL TRANSMITTER/RETRANSCEIVER AND METHOD THEREOF

摘要

The present invention relates to an apparatus for optical transmission and reception based on multicarrier differential phase shift keying, comprising: a multicarrier generating unit which outputs at least two optical signals having different wavelengths; and at least two optical modulation units which receive each of at least two optical signals outputted by the multicarrier generating unit, wherein each of at least two optical modulation units phase-modulates the received optical signal to electrical signals applied in a pair.
