    • The present invention enables the usable bandwidth of an optical fiber transmission link to be increased. The transmission fiber of the link with a is coupled with a dispersion compensation fiber (DCF+) that has a positive dispersion and a dispersion slope such that the relative dispersion slope (RDS) of the DCF+ is lower than the RDS of the transmission fiber. Because the RDS of the DCF+ is lower than the RDS of the transmission fiber, the RDS of the combination of the transmission fiber and the DCF+ below the RDS of the transmission fiber. When the DCF+ is combined with a DCF having a negative dispersion (DCF−), the transmission link is dispersion compensated by DCF− and the usable bandwidth of the optical fiber transmission link is increased compared to the compensation of the transmission fiber by a single DCF−.
    • 本发明能够提高光纤传输链路的可用带宽。 与a的链路的传输光纤与具有正色散和色散斜率的色散补偿光纤(DCF +)耦合,使得DCF +的相对色散斜率(RDS)低于传输光纤的RDS。 由于DCF +的RDS低于传输光纤的RDS,传输光纤和DCF +的组合的RDS低于传输光纤的RDS。 当DCF +与具有负色散(DCF-)的DCF组合时,传输链路被DCF-进行色散补偿,并且与通过单个DCF的传输光纤的补偿相比,光纤传输链路的可用带宽增加 - 。
