IPC: H04B10/29
Filed: 1989-08-25
Abstract: In an all-optical data network, a plurality of subscriber stations are to be able to communicate with one another bidirectionally via the same optical waveguide and only one type of electro-optical circuit arrangement is to be used. The optical amplifiers (OVn, OVn+1, ...) incorporated in the optical waveguide network are equipped with additional input and output circuits for electric signals and are set up for the operating modes "Optical amplification/simultaneous reception signal conversion/transmission signal conversion". They are located at the subscriber terminal stations and replace the optical couplers and different opto-electronic components found in conventional networks. In the lasers in the optical amplifiers (OVn, OVn+1, ...), the optical strip line conductor also operates bidirectionally. The optical waveguide network does not therefore need to be designed as a closed ring and can be extended as required. Use as a local area network, processor bus system etc. <IMAGE>
