Latest Patents
One of Dongsheng Zhang's latest patents is titled "Method and apparatus for laser overlap detection." This invention discloses systems and methods aimed at detecting whether an Optical Network Unit (ONU) in a network may be causing communications interference due to laser overlap. In this patent, an Optical Line Terminal (OLT) identifies a pair of ONUs suspected of causing laser overlap and strategically allocates transmission windows to communicate effectively. If messages from the ONUs are not received as expected, then the OLT deduces potential interference.
Another notable patent is focused on "Congestion control in an optical line terminal." This innovation outlines systems and methods for detecting and managing congestion within an OLT. By enforcing maximum upstream bandwidth via a Dynamic Bandwidth Allocation (DBA) algorithm across multiple ports, the system enhances data communication efficiency. If congestion occurs, the OLT can adaptively modify the bandwidth allocation, thus maintaining optimal performance.
