ABSTRACT:
A new two-way WDM optical transmission system is provided. The WDM optical transmission system comprises a two-way optical fiber cable, a first dispersion compensation optical fiber (DCOF) connected to one end of the optical fiber cable, a second DCOF connected to another end of the optical fiber cable, a chromatic dispersion compensating transmitter unit and a chromatic dispersion compensating receiver unit. The two-way optical fiber cable comprises a plurality of segments. The first DCOF is connected to one end of the optical fiber cable and has a compensation amount of a half of a one segment dispersion D.sub.c of the optical fiber cable. The second DCOF is connected to another end of the optical fiber cable and has the compensation amount of the half of the one segment dispersion D.sub.c. And the chromatic dispersion compensating transmitter unit compensates accumulated residual chromatic dispersions to be caused by higher-order wavelength dispersion of the optical fiber cable at each signal wavelength. Further, the chromatic dispersion compensating receiver unit compensates accumulated residual chromatic dispersions caused by higher-order wavelength dispersion of the optical fiber cable at each signal wavelength. The chromatic dispersion compensating transmitter unit has a plurality of optical transmitters, a multiplexer combining a plurality of different wavelength bands and a plurality of chromatic dispersion compensators. And the chromatic dispersion compensating receiver unit has a demultiplexer, a plurality of optical receiver and a plurality of chromatic dispersion compensators.
