ABSTRACT:
An optical transmission system including an optical transmitting device and an optical receiving device. The optical transmitting device includes a data signal splitting section for splitting data signal information into at least two parts and generating at least two electrical signals having different center frequencies and bands, a frequency multiplexing section for performing frequency multiplexing for the at least two electrical signals, and an electrical-to-optical conversion section for converting the frequency-multiplexed signal to an optical signal and sending it to an optical transmission path. The optical receiving device includes an optical-to-electrical conversion section for converting the optical signal to a frequency-multiplexed signal, a band demultiplexing section for demultiplexing the frequency-multiplexed signal to obtain at least two electrical signals, and a data signal recovering section for recovering the data signal based on the at least two demultiplexed electrical signals.
