An optical transmission system |
摘要 |
An optical transmission system is described that can perform not only the amplification of an optical signal but also dispersion pre-equalization, since the signals are optical. The optical power level of an optical signal propagating through a dispersion medium 101a is amplified in an optical amplifier 102, the signal becoming an optical signal a. A phase modulator driving circuit 104 outputs a signal b corresponding to the envelope signal of the optical signal a. An optical phase modulator 103 to which the signals a and b are applied phase-modulates the input optical signal a, and outputs an optical signal d upon which dispersion pre-equalization is carried out in dispersion medium 101b. <IMAGE> |
