  • Patent number: 11923898
    Abstract: Local birefringence is determined from a scatter signature of a birefringent waveguide. Four copies of a Rayleigh scatter time delay domain signature of the fiber are collected from two orthogonal polarization received states and from two orthogonal polarization launched states to form a Jones transfer matrix. Obtaining the Jones transfer matrix for the waveguide eliminates the need to align the instrument polarization launch state to the birefringence axes. Birefringence is determined from an autocorrelation of a polarization state averaged function calculated from the transfer matrix terms. Alternatively, the transfer matrix is rotated until fast and slow eigenvectors are separated, fast and slow amplitude functions are generated, and a cross-correlation is performed on the fast and slow amplitude functions in order to determine the birefringence.

  • Patent number: 11889243
    Abstract: Embodiments of the present application provide a method and apparatus for opening a quiet window, and a registration method, apparatus and system. The method for opening a quiet window includes that: a first quiet window is opened when it is determined that the first quiet window needs to be opened, wherein the first quiet window is used for Optical Network Unit (ONU) discovery. According to the embodiments of the present application, a first quiet window is opened only when it is determined that the first quiet window needs to be opened, rather than periodically opening the first quiet window, such that the efficiency of the first quiet window is improved and the impact of the first quiet window on a data transmission delay is reduced, thereby reducing a transmission delay of a Passive Optical Network (PON) system.

  • Patent number: 11863919
    Abstract: Techniques for identifying sources of degradations within a PON include detecting that an optical profile of a segment of the PON is outside of a designated operating range, and comparing the drift over time of the segment's optical profile with respective drifts over time of optical profiles of other PON segments, each of which shares an OLT or a last mile termination unit with the segment as a common endpoint. Each segment's optical profile corresponds to characteristics of optical signals delivered over the segment (e.g., attenuation, changes in frequencies, changes in power outputs, etc.). The differences between the segments' drift(s) over time are utilized to determine the source of a degradation within the PON, and may be utilized to identify a particular component of the segment (e.g., the OLT, the last mile termination unit, or an optical fiber included in the segment) as being the source of the degradation.
