  • Active wavelength converter for use with an optical time-domain reflectometer (OTDR) and method for increasing OTDR supervision distance range
    Patent number: 7369219
    Abstract: A converter device that changes the wavelength of optical signals originated by an OTDR to supervise optical networks, in a manner that eliminates the traffic signal interference in the supervision signal, is provided. A method for increasing the OTDR supervision distance range, wherein the converters are placed at route points where the optical signal from the OTDR reaches its useful attenuation limit and needs to be recovered, reducing the number of OTDRs utilized in the supervision system, is also provided.
