Title:
光伝送装置
Document Type and Number:
Japanese Patent JP4592170
Kind Code:
B2
Abstract:
Optical signals inputted to input ports (101a to 101f) are split in half by 1 × 2 optical splitters (102a to 102f) respectively and the resulting signals are inputted to the input terminals of an optical matrix switch (103). The optical matrix switch (103) switches between the routes of the individual optical signals and outputs the signal at any of the output ports (104a to 104f). This enables the optical signal from the same input port to be outputted at two different output ports, which makes it possible to effect "bridge" at the time of protection switching.
