【実用新案登録請求の範囲】[Scope of utility model registration request] ループ式伝送システムに於いては、ループ状伝 送路を有するわけですが、ループにそつて流れる 一方向の光信号を、分岐し、受信信号とする受信 分岐器、又、ループに返してやる受信信号に送信 信号を結合させる合成器を機能とする双方向光分 岐器の回路構成を範囲とする。 A loop-type transmission system has a loop-shaped transmission line, and there is a receiver splitter that branches the unidirectional optical signal flowing along the loop into a received signal, and a receive signal that returns it to the loop. The scope of this research is the circuit configuration of a bidirectional optical splitter whose function is a combiner that combines transmitted signals.
