Abstract

A 34 Mb/s time-division photonic switching system is proposed. This system has significance in fiber sensor distribution networks and B-ISDN networks. A novel optical network is constructed. It consists of a 4 X 4 optical waveguide switch, a 1 X 4 fiber coupler, four fiber delay lines and polarization controllers. The wavelength in use is 1.3 micrometers . Four telephones are used as demonstrated terminals. All of the possible switching modes among four subscribers can work properly under the control of a micro-computer. Besides processing the normal audio signal and other integrated data, this system is also working in word-by-word mode. One word--the basic data structure and processing unit in this system--consists of eight bits. Moreover, one word can hold more than eight bits, so the throughput of the system can be promoted highly. System reliability and probability in public networks are discussed.
