Title:
OPTICAL FIBER NETWORK FAULT DETECTION METHOD, DEVICE, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/206371
Kind Code:
A1
Abstract:
An optical fiber network fault detection method, device, and system. The method comprises: transmitting a first optical signal to an optical fiber link and obtaining information returned from the optical fiber link, the optical fiber link being provided with one or more optical fiber reflectors used for dividing the optical fiber link into different regions, each optical fiber reflector being configured to: reflect a second optical signal of a predetermined wavelength and transparent-transmit a third optical signal of an another wavelength, the wavelength of the first optical signal comprising: one or more of the wavelengths of the second optical signals that can be reflected by the one or more optical fiber reflectors, and the information returned from the optical fiber link comprising: the wavelength of the reflected second optical signal; and performing fault detection on the optical fiber link according to the information returned from the optical fiber link, the wavelength of the reflected second optical signal being used for determining a region divided by the optical fiber reflector and corresponding to the wavelength.
