Abstract

The compensation characteristics of the distorted WDM channels compensated for by dispersion management (DM) and optical phase conjugation in the long-haul ($50\;fiber\;spans{\times}80km$) transmission link with the randomly distributed single mode fiber (SMF) length and residual dispersion per spans (RDPS) for implementing of the flexible link configuration are investigated. It is confirmed that the compensation effect in the link with the randomly distributed SMF length and RDPS is similar with that in the link with the uniform distribution, when the launch power of WDM channels are restricted within 0 dBm. This result means that the proposed link configuration is useful for designing and deploying the long-haul WDM transmission link.

장거리 ($50\;fiber\;spans{\times}80km$) 전송 링크의 융통적 구성을 위해 단일 모드 광섬유 (SMF; single mode fiber)의 길이와 중계 구간 당 잉여 분산 (RDPS; residual dispersion per span)이 랜덤하게 분포하는 링크에서 광 위상 공액과 결합된 분산 제어 (DM; dispersion management)를 통한 왜곡된 WDM 채널의 보상 특성을 살펴보았다. WDM 채널들의 입사 전력이 0 dBm 이하로 제한된다면 SMF 길이와 RDPS가 랜덤하게 분포하는 링크를 통한 보상 효과가 균일하게 분포하는 링크에서의 보상 효과와 유사하게 나타나는 것을 확인하였다. 이는 제안한 랜덤 분포 링크 구조를 이용하면 장거리 WDM 전송 링크 설계와 구축에서 융통성을 확보할 수 있다는 것을 의미한다.
