Title: Innovations of David G Cunningham
Introduction
David G Cunningham is an accomplished inventor based in Cupertino, CA. He holds a total of 3 patents that showcase his expertise in optical technologies. His work has significantly contributed to advancements in optical fiber communication.
Latest Patents
One of his latest patents is titled "Method and apparatus for providing a linear phase mode-matched launch of light into an end of a multimode optical fiber." This invention provides a method and apparatus for launching light into a multimode optical fiber (MMF) in a way that excites higher-order Hermite Gaussian (HMG) mode groups. This innovation increases the bandwidth of the optical link while reducing modal noise. Additionally, it allows for greater manufacturing tolerances, as precise alignment between connectors is not critical for achieving successful light launches.
Another significant patent is "Open fiber control for optical transceivers." This invention implements a system that allows optical transceivers to manage signal transmission safely. When a connection is intact, the transceiver can transmit at higher power levels, increasing data rates and transmission distances. However, if the connection breaks, the transceiver automatically reduces power to safe levels, ensuring user safety while maintaining performance.
