Schaltungsanordnung zum redundanten Aufbau in Kommunikationssystemen

摘要

Centralised and decentralised units of a communications system are interlinked according to the prior art via cross-connecting lines. The resulting high cabling cost is reduced according to the invention by connecting optical filters to the transmission devices. In particular, an optical filter with a combining function is connected at the transmitting end to transmission devices in a reciprocally redundant configuration. Optical filters with a dividing function are connected at the receiving end to the respective transmission devices.
