OPTICAL SWITCH CONTROL CIRCUIT FOR ALL-OPTICAL RING NETWORK

摘要

The circuit comprises a signal divergence means(2), an address processing means(9), a path converting means(7) and a switch controlling means(10) for providing an operating pulse of the first or second level. The switch controlling means(10) includes two input ports, an optical filter combination means(2a), the first output port data frame abstraction means(11) having the second output port, the first and second multiple quantum well PIN diodes, and switch operating means(12).
