Abstract:
Optical repeater equipment having optical amplifiers for amplifying multiplexed optical signals, said optical repeater equipment to be placed between first and second pieces of optical terminal equipment, said first piece of optical terminal equipment having a function to form a multiplexed optical signal by multiplexing a plurality of optical signals of mutually different wavelengths, and to collect information for supervision of the transmission of the multiplexed optical signal, said optical repeater equipment comprising:first extracting means for extracting part of the multiplexed optical signal including respective parts of the plurality of optical signals of mutually different wavelengths;first separating means for separating the extracted part of the multiplexed optical signal into the component rays of mutually different wavelengths;first detecting means for detecting the wavelengths of the separated component rays;generating means for generating a supervisory control signal including a signal showing detected wavelengths of the separated component rays; andsending means for sending the supervisory control signal in the direction of the first piece of optical terminal equipment.
