Latest Patents
One of Fengkun Liu's latest patents is titled "Fast protection switching by snooping on upstream signals in an optical network." This invention involves an optical network with an optical splitter connected to both a working optical subscriber unit (OSU) and a protection OSU. The innovation enables rapid protection switching from the working OSU to the protection OSU by measuring the arrival times of upstream signals during ranging operations. This allows for effective communication with optical network terminals (ONTs) without requiring extensive ranging procedures.
Another notable patent is the "Health check algorithm for protection circuit in optical network." This algorithm assesses the functionality of the protection OSU by applying a reset pulse at specific timing positions. It interprets the current upstream cell received at the protection burst mode receiver (BMR). If the upstream cells are not correctly interpreted after several attempts, the protection circuit is deemed to have failed. This algorithm enhances the reliability of optical networks by ensuring that protection circuits are functioning properly.
