Upon graduation, he began working at the Martin Marietta Company in the area of space instrumentation.
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.
Press coverage at that time noted that the firm would “specialize in equipment such as lasers, modulators, and amplifiers used to send data through fiber cables at very high rates.
"[4] Referred to as wave division multiplexing, the new technology would, according to William H. Culver, Optelecom's chairman, let “a single, hair-thin cable carry many signals simultaneously, with each one being piggybacked on a different frequency of light.
