Abstract

A high-performance optical and electronic integrated switch capable of effectively extending the transmission distance includes a network processor that controls the functions of the packet switch, a plurality of optical transceivers provided near the processor and having a photoelectric conversion function, and an optical relay switch. A plurality of optical waveguides are connected to the input and output sides of the optical relay switch. Each optical transceiver has a regeneration function that performs optical-electrical conversion on inputted optical signals, then turns back the converted signals, and performs signal conversion on them, and its input side is connected with a routing optical waveguide included in the optical waveguides on the output side of the switch and its output side is connected with a routing optical waveguide included in the optical waveguides on the input side of the switch. The optical waveguides include ones for connecting to an external communication counterpart.
