Title: Piet Van Heyningen: Innovator in Optical Network Technologies
Introduction
Piet Van Heyningen is a notable inventor based in Almere, Netherlands. He has made significant contributions to the field of optical networks, holding 2 patents that showcase his innovative approach to technology.
Latest Patents
One of his latest patents is a health check algorithm for protection circuits in optical networks. This invention involves an optical network with an optical splitter connected to a working optical subscriber unit (OSU) and a protection OSU. The algorithm determines if the protection OSU is functioning improperly by applying a reset pulse at specific timing positions and interpreting the current upstream cell received. If no upstream cells are correctly interpreted after several cycles, the protection circuit is deemed to have failed. This algorithm is based on a cell delineation procedure implemented as a state machine.
Another significant patent by Van Heyningen is focused on fast protection switching by snooping on downstream signals in an optical network. This invention allows for rapid switching from the working circuit to the protection circuit by measuring the arrival times of corresponding downstream cells. The information related to these arrival times is transmitted to the protection OSU, which generates a propagation delay value for effective communication during protection switching.
