<P>PROBLEM TO BE SOLVED: To achieve excellent transmission characteristics by reliably compensating an error in received data caused by a modulation system or the multiplex system of an optical signal capable of transmitting multi-bit information within one symbol time when the optical signal is transferred. <P>SOLUTION: Provided is an optical transmission system, where in an optical transmitter 10 a detection bit having a specific pattern set according to the number of bits to be transmitted within one symbol time, is imparted with respect to a transmission signal in which transmission information has been encoded according to a preset format, and an optical signal generated by modulating light according to the transmission signal is transmitted to a transmission line 20. In an optical receiver 30, logic inversion or bit swap of received data is detected and compensated by using the detection bit included in the received signal, a decoding process of the compensated received signal is executed. <P>COPYRIGHT: (C)2009,JPO&INPIT |
