| 摘要 |
A passive optical telecommunication system comprises a passive light waveguide bus network with optical branchers extending between a central telecommunication equipment and a plurality of decentralized telecommunication equipment. An electro-optical transmission element, an opto-electrical receiving element and a filter for bidirectional wave-division multiplexing are respectively structurally combined to form an electro-optical/opto-electrical transmitting/receiving module only in the decentralized telecommunication equipment and the electro-optical transducer, opto-electrical transducer and a filter for bidirectional wave-division multiplexing are respectively structurally separate, discrete components only in the centralized telecommunication equipment. |
