The invention provides a method, equipment and a device for measuring branch optical fibers. The optical fiber network comprises at least two branch optical fibers, each branch optical fiber is connected with a grating sequence, a group of test wavelengths is selected, the group of test wavelengths includes but not limited to the reflection wavelength of grating sequence of all branch optical fibers in optical network, a group of wavelength row vectors built according to the group of test wavelengths are mutually orthogonal, and the group of wavelength row vectors comprises a wavelength row vector corresponding to each branch optical fiber; a group of test wavelengths is adopted to test the optical network, so as to obtain detection curve data corresponding to each test wavelength; detection curve data corresponding to each test wavelength forms a test matrix, and the detection curve data corresponding to each test wavelength is taken as a row vector of the test matrix; the wavelength row vector corresponding to the object branch optical fiber multiples the test matrix, so as to obtain the test result data of the branch optical fiber. The adoption of the method, the equipment and the device can decrease engineering application difficulty.
Description
technical field [0001] The invention relates to communication technology, in particular to a method, device and equipment for detecting branch optical fibers. Background technique [0002] Optical Time Domain Reflectometer (OTDR for short) is an optoelectronic integrated instrument made by using the backscattering produced by the Rayleigh scattering of light in the optical fiber and the Fresnel reflection produced by the discontinuous point in the optical fiber. In the passive optical network (Passive Optical Network, referred to as PON) network, the OTDR is used for the acceptance of the network laying and the later operation and maintenance. [0003] At present, when using the OTDR instrument to test the branch fibers of the PON network, it is necessary to install a Fiber Bragg Grating (Fiber Bragg Grating, FBG) at the end of each branch fiber, and the reflection wavelength of the FBG installed on each branch fiber is different. The reflection wavelength of the FBG is use...
