Abstract: 광신호 분리 및 합파 장치에서, 파장이 각각 다른 다수의 광신호가 광섬유를 통하여 전송되면, 설정 파장의 광신호만이 파장 분리 필터에 의하여 투과된다. 이 때, 파장 분리 필터의 투과 특성에 따라 설정 파장 이외의 파장을 가지는 광신호가 함께 투과된다. 이러한 잡음 광신호는 광섬유 격자에 의하여 반사됨으로써, 설정 파장 광신호만이 해당 광섬유를 통하여 해당 기지국으로 전송된다.
또한, 각각 별도의 광섬유를 통하여 전송되는 파장이 다른 다수의 광신호는 해당 광섬유 격자와 파장 분리 필터를 차례로 통과 및 반사됨으로써, 합파되어 전송된다. 이에 따라 필터 특성에 의한 신호 손실이 감소되고, 신호의 아이솔레이션이 향상되어 잡음에 의한 에러율이 감소됨으로써, 전송 효율이 극대화된다.
