  • Testing optical fiber link continuity using OTDR backscattering patterns
    Patent number: 11879802
    Abstract: There are provided methods and systems for testing the continuity of optical fiber links under test and/or a fiber arrangement, polarity or mapping of optical fiber connections within optical devices under test using the backscattering pattern as a signature. The device under test may comprises a single fiber, a duplex link, a multifiber cable or another multi-port device such as a backplane device.
    Type: Grant
    Filed: October 19, 2021
    Date of Patent: January 23, 2024
    Assignee: EXFO Inc.
    Inventors: Stephane Perron, Michel Leclerc, Pascal Gosselin-Badaroudine
  • Optical fiber recognition using backscattering pattern
    Patent number: 11650128
    Abstract: There are provided methods and systems that enable the use of the backscattering pattern produced by an optical fiber in an OTDR trace as a signature (also referred to herein as the “RBS fingerprint”) to recognize an optical fiber. It was found that it may be difficult to obtain repeatable signatures as those are sensitive to the wavelength of the OTDR laser source and the temperature of the fiber. OTDR methods and systems that are adapted to compare the backscattering pattern in a more repeatable manner are therefore provided. Once the repeatability issue is overcome, such signature can be used for identification purposes and enable new applications.
