Claims (1)

  1. 복수의 단말 스테이션과 상기 스테이션에 접속되어 광신호를 전송하므로써 상기 각 스테이션간의 통신을 행하게 되어있는 광전송로등으로 구성된 광네트워크 시스템에 있어서, 상기 스테이션은 전송되는 데이터신호를 바이너리값의 상태에 따라 파장 λ1과 λ2의 2가지 광신호로 변환시키고 합성하여 상기 광전송로로 송출하는 수단과, 다른 스테이션으로부터 송출되어 온 광신호를 수신하여 파장 λ1과 λ2의 광신호로 분리시키는 수단, 분리된 파장 λ1과 λ2의 광신호가 중첩되어있는지를 검출해내는 수단등을 구비하여서, 파장 λ1과 λ2의 광신호가 일정시간이상에 걸쳐서 중첩되어 있다는 것을 검출하였을 경우에는 복수의 각 스테이션으로부터 전송된 신호가 충돌상태에 있다고 판정하는 것을 특징으로 하는 광 네트워크 시스템.
