장거리 WDM(wavelength-division-multiplexed) 전송 시스템에서 더 짧은 파장과 더 긴 파장의 신호는 분산 보상 후에도 분산 기울기로 인해 SPM-GVD(자기 위상 변조) 페널티가 발생합니다. 수신기가 최적화되었습니다. 이에 대한 대책으로 우리는 이미 각 채널의 송신기와 수신기에서 색분산의 사전 보상과 사후 보상을 모두 제안했습니다. 이 방법은 전송 라인을 따라 경로 평균 색분산의 채널 변화를 감소시킬 수 있으며 전송 후 파형의 아이 오프닝을 향상시킬 수 있습니다. 우리는 송신기에서 색분산과 처핑의 최적화된 매개변수를 조사했습니다. 최적화된 사전 분산 보상 매개변수 R 50% 정도였다. 신호 파장이 평균 영분산 파장보다 작을 때 최적화된 처핑 매개변수 α는 약 3이었습니다. 5.3km 직선에 대한 단일 채널, 4,760Gbit/s NRZ 신호 전송 실험에서 이 방법은 SPM-GVD 페널티를 줄였습니다. 순환 루프를 사용한 32km에 대한 5.3채널, 9,879Gbit/s WDM 전송 실험에서 이 방법이 개선되었습니다. Q-1번째 및 32번째 채널에 대한 요소가 1.5dB 이상 증가합니다.

Abstract: In long-haul wavelength-division-multiplexed (WDM) transmission systems, signals with shorter and longer wavelengths have self-phase modulation group-velocity-dispersion (SPM-GVD) penalty caused by to the dispersion slope even after the dispersion-compensation at the receiver has been optimized. As a countermeasure, we have already proposed both pre-compensation and post-compensation of chromatic dispersion at the transmitter and receiver for each channel. This method can decrease the channel variation of path-averaged chromatic dispersion along the transmission line, and it can improve the eye opening of the waveform after transmission. We investigated the optimized parameter of chromatic dispersion and chirping at the transmitter. The optimized pre-dispersion compensation parameter R was about 50%. The optimized chirping parameter α was about 3 when the signal wavelength was less than the mean zero-dispersion wavelength. In a single-channel, 5.3-Gbit/s NRZ signal transmission experiment over a 4,760-km straight line, this method decreased SPM-GVD penalty. In a 32-channel, 5.3-Gbit/s WDM transmission experiment over 9,879 km using a circulating loop, this method improved Q-factors for the 1st and 32nd channels by more than 1.5 dB.
