  • TUNABLE DENSE WAVELENGTH DIVISION MULTIPLEXING (DWDM) OPTICAL TIME-DOMAIN REFLECTOMETER (OTDR)-BASED OPTICAL FIBER MONITORING
    Publication number: 20230361869
    Abstract: In some examples, a tunable dense wavelength division multiplexing (DWDM) optical time-domain reflectometer (OTDR) may include a fiber optic link analyzer, executed by at least one hardware processor, to determine, based on a user input, for a fiber optic link of a plurality of fiber optic links of a fiber optic cable, whether the fiber optic link is active or not active. The DWDM OTDR may specify, based on a determination that the fiber optic link is active, a test wavelength that is different from a data transmission wavelength of data transmitted by the fiber optic link. A DWDM multiplexer may be collocated with the DWDM OTDR to selectively connect, based on the specified test wavelength, the DWDM OTDR to the fiber optic link of the plurality of fiber optic links for testing of the fiber optic link.

  • Tunable dense wavelength division multiplexing (DWDM) optical time-domain reflectometer (OTDR)-based optical fiber monitoring
    Patent number: 11742941
    Abstract: In some examples, a tunable dense wavelength division multiplexing (DWDM) optical time-domain reflectometer (OTDR) may include a fiber optic link analyzer, executed by at least one hardware processor, to determine, based on a user input, for a fiber optic link of a plurality of fiber optic finks of a fiber optic cable, whether the fiber optic fink is active or not active. The DWDM OTDR may specify, based on a determination that the fiber optic fink is active, a test wavelength that is different from a data transmission wavelength of data transmitted by the fiber optic fink. A DWDM multiplexer may be collocated with the DWDM OTDR to selectively connect, based on the specified test wavelength, the DWDM OTDR to the fiber optic fink of the plurality of fiber optic links for testing of the fiber optic link.
