Abstract

The implementation possibility of the flexible optical network configuration using the non-midway optical phase conjugator (OPC) in the dispersion-managed (DM) optical link for wavelength division multiplexed (WDM) transmission is demonstrated in this paper. It is confirmed that the implementation possibility of flexible link configuration is more increased, as number of fiber spans is more bigger and the residual dispersion per span (RDPS) is more large. It is also confirmed that the non-midway OPC link, in which RDPS of the latter half transmission section (after OPC) is decided by the averaged RDPS of the former half transmission section (before OPC), has more advantage for the flexible network configuration.

전통적인 midway 광 위상 공액기 (OPC; optical phase conjugator)가 아닌 non-midway OPC를 분산 제어 (DM; dispersion-managed) 광전송 링크에 적용하여 파장 분할 다중 전송 (WDM; wavelength division multiplexed)을 위한 융통적인 네트워크의 구성 가능성을 분석하였다. 중계 구간의 수가 많을수록, 또한 중계 구간 당 잉여 분산 (RDPS; residual dispersion per span)이 클수록 non-midway OPC를 통한 유연한 링크의 구성 가능성이 커지는 것을 확인하였다. 아울러 OPC 이후의 후반 전송 구획을 구성하는 각 중계 구간의 RDPS를 OPC 이전의 전반 구획의 RDPS의 평균값으로 설정하는 링크 구조가 융통적 링크 구성에 더욱 유리하다는 것을 확인하였다.
