 Working at Optelecom from 1983 to 1988, Huber developed optical multiplexed sensors and a multiplexed fiber optic wideband data distribution system.In 1988, he joined General Instrument Corporation, where he patented several inventions, including Remote pumping for active optical devices, Method for producing a tunable erbium fiber laser, and wavelength selective coupler for high power optical communications.These technologies were core elements of the wave division multiplexing (“WDM”) system developed by Huber.
