가입자망에서 통신 이용량이 매우 빠른 속도로 증가되고 있다. 수동적인 광 네트워크로 구현되는 가입자망은 광대역, 장거리 전송, 투명성의 특성을 갖는 네트워크로 설계할 수 있다. 특히 WDM과 WGR의 기술은 WDM-PON의 새로운 가입자망 구성을 가능하게 한다. 본 논문은 광 가입자망의 구성요소들을 결정하는 알고리즘을 제안하고 여러 구조들에 대한 비용을 분석하는 한편 생존성을 갖는 광 가입자망 구성 방안을 연구함으로써 경제적이고 신뢰성 있는 국내 광가입자망 구축 방향을 제시하고자 한다. 분석 결과에 의하면 여러 광가입자 구성 중에서 다중 성형 구조가 가장 경제적인 구조로 분석되었다.
