OPC(Optical Phase Conjugation)는 광섬유 비선형성을 완화하기 위한 전광 신호 처리 기술이며 광-전기-광 변환이 거의 없고 증폭 간격이 긴 비용 효율적인 광섬유 네트워크를 구축하는 데 유망합니다. 집중 증폭 시스템에서 OPC는 전송 광섬유에서 전파되는 동안 전력 및 색 분산(CD) 맵의 비대칭으로 인해 교차 위상 변조(XPM)에 의해 유발된 비선형 왜곡에 대해 약간의 비선형 완화 효율성을 갖습니다. 또한 OPC의 CD 보상 효과로 인해 XPM으로 인한 잡음의 워크오프가 작아지므로 결정론적 비선형 왜곡이 증가합니다. 따라서 OPC를 갖춘 집중 증폭 전송 시스템은 기존 시스템보다 채널 간격에 더 민감합니다. 본 논문에서는 OPC를 갖춘 증폭 중계기를 사용하여 NZ-DSF 전송의 채널 간격 의존성을 보여줍니다. 수치 시뮬레이션은 100Gbps/λ WDM 신호에서 채널 간격과 CD 간의 포괄적인 특성을 보여줍니다. 주기적으로 폴링된 LiNbO를 사용한 실험적 검증3기반 OPC도 수행됩니다. 이러한 결과는 채널 간격 설계가 기존의 분산 비관리 시스템보다 OPC 지원 시스템에서 더 중요하다는 것을 시사합니다.

Abstract: Optical phase conjugation (OPC) is an all-optical signal processing technique for mitigating fiber nonlinearity and is promising for building cost-efficient fiber networks with few optic-electric-optic conversions and long amplification spacing. In lumped amplified systems, OPC has a little nonlinearity mitigation efficiency for nonlinear distortion induced by cross-phase modulation (XPM) due to the asymmetry of power and chromatic dispersion (CD) maps during propagation in transmission fiber. In addition, the walk-off of XPM-induced noise becomes small due to the CD compensation effect of OPC, so the deterministic nonlinear distortion increases. Therefore, lumped amplified transmission systems with OPC are more sensitive to channel spacing than conventional systems. In this paper, we show the channel spacing dependence of NZ-DSF transmission using amplification repeater with OPC. Numerical simulations show comprehensive characteristics between channel spacing and CD in a 100-Gbps/λ WDM signal. An experimental verification using periodically poled LiNbO3-based OPC is also performed. These results suggest that channel spacing design is more important in OPC-assisted systems than in conventional dispersion-unmanaged systems.

AB - Optical phase conjugation (OPC) is an all-optical signal processing technique for mitigating fiber nonlinearity and is promising for building cost-efficient fiber networks with few optic-electric-optic conversions and long amplification spacing. In lumped amplified systems, OPC has a little nonlinearity mitigation efficiency for nonlinear distortion induced by cross-phase modulation (XPM) due to the asymmetry of power and chromatic dispersion (CD) maps during propagation in transmission fiber. In addition, the walk-off of XPM-induced noise becomes small due to the CD compensation effect of OPC, so the deterministic nonlinear distortion increases. Therefore, lumped amplified transmission systems with OPC are more sensitive to channel spacing than conventional systems. In this paper, we show the channel spacing dependence of NZ-DSF transmission using amplification repeater with OPC. Numerical simulations show comprehensive characteristics between channel spacing and CD in a 100-Gbps/λ WDM signal. An experimental verification using periodically poled LiNbO3-based OPC is also performed. These results suggest that channel spacing design is more important in OPC-assisted systems than in conventional dispersion-unmanaged systems.
