COMMUNICATION SYSTEM FOR ANALOG AND DIGITAL COMMUNICATION SERVICES

摘要

A first and a second interconnection unit comprising a respective first and a second communication interface, a first and a second electro-optical converter, and a multiplexing unit, is disclosed. The first interconnection unit is adapted to receive electrically transmitted analog and digital information, convert said information into electrically transmitted information, and to multiplex the information so as to enable transmission over a bidirectional link. The second interconnection unit is adapted to receive and de-multiplex the transmitted analog and digital information, to convert it back into electrically transmitted analog and digital information, and to output said information. A system comprising the first and second interconnection units is also disclosed. The system is adapted for supplying both analog services and digital services with communication information over the bidirectional link.

1. A first interconnection unit (100) comprising a first and a second communication interface, a first and a second electro-optical converter (110, 120), and a multiplexing unit (130), the first interconnection unit being adapted to:
receive, at the first communication interface, a first stream of electrically transmitted analog information (A1E); convert, at the first electro-optical converter (110), said first stream of electrically transmitted analog information (A1E) into a first stream of optically transmitted analog information (A1O); receive, at the second communication interface, a first stream of electrically transmitted digital information (D1E); convert, at the second electro-optical converter (120), said first stream of electrically transmitted digital (D1E) information into a first stream of optically transmitted digital information (D1O); multiplex, at the multiplexing unit (130), said first stream of optically transmitted analog information (A1O) and said first stream of optically transmitted digital information (D1O); and output said multiplexed information (A1O, D1O) over a bidirectional link (40).
