WAVELENGTH DIVISION MULTIPLEXING OPTICAL TRANSMISSION DEVICE

摘要

[Problem] In relation to optical communication of a wavelength-division multiplex method, provided is an an optical transmission device capable of performing transmission of an optical signal wherein the influence of waveform distortion or the like generated when the optical signal passes through a device or the like on a transmission line is suppressed, and deterioration of waveform is accordingly small.;[Means for solution] The optical transmission device comprises a multiplexing means 80, an amplification means 81 and an optical signal correction means 82. The multiplexing means 80 multiplexes together optical signals inputted to it by means of paths in accordance with respective channels of the optical signals, and outputs thus produced signal as a multiplexed signal. The amplification means 81 amplifies the multiplexed signal and outputs thus produced signal as an amplified signal. The optical signal correction means 82 corrects the amplified signal in terms of each channel and outputs thus produced signal as a corrected signal. By sequentially connecting the multiplexing means 80, the amplification means 81 and the optical signal correction means 82 in this order, the influence of waveform distortion of an optical signal or the like can be suppressed.
