Document Type and Number:
Japanese Patent JP5583788
Kind Code:
B2
Abstract:
The present invention relates to a technique for reducing a necessary bandwidth of an optical receiver in an optical OFDM communication system. Optical OFDM signals of different spectra are alternately transmitted for each OFDM symbol time, and, after this light is transmitted via an optical fiber, the light undergoes photoelectric conversion by a delay interferometer having a delay time equal to one symbol time and a balanced direct detection receiver and is received.
