Latest Patents

Weijun Li holds a patent for "Methods and apparatus for identifying a passive optical network failure." This patent describes a method and corresponding apparatus for determining when a specific Optical Network Terminal (ONT) in a PON is malfunctioning. The invention involves sending a continuous stream of light up a shared fiber, which can adversely affect communications between the ONT and an Optical Line Terminal (OLT). The embodiment verifies that the failure is due to a faulty optical transmitter in the ONT, rather than other network faults, such as a fiber optic line cut or power outage. This automated method allows service providers to quickly identify which specific ONT is malfunctioning.
