초록

현재의 전송네트워크용량을 향상시킬때 중요하게 고려해야 할것중의 하나가 네트워크 scalability 이다. 새로운 풀 메쉬의 링 확장 방법 및 플래닝 툴을 제안하였다. 3$\sim$15 노드의 확장링에서 본 툴을 사용하여 SNR이 증진되는 것을 입증하였다. 노드의 출력신호 및 광 SNR이 제안된 NPOT에 의해 -16dBm/10dB 에서 +005dBm/21dB 로 증진되었다.

One of the major issues that has to be carefully considered when upgrading current transport network capacity, is network scalability. A novel full-meshed connected ring expansion methodology and planning tool have been proposed. A 3 to 15 node expansion ring has been studied by demonstrating a dramatic system SNR improvement when the proposed planning tool was used. The results are that node output signal and optical SNR have been improved from -16dBm/10dB to +005dBm/21dB by NPOT.
