CORNING, NY, August 30 -- Corning Inc. will spend more than $20 million to multiply its ability to produce liquid crystal display devices by six. The investment will go towards the company's ability to manufacture the PurePath Dynamic Spectral Equalizer and Wavelength Selective Switch, which are PurePath wavelength management devices based on liquid crystal technology. The devices provide high channel-count bandwidth management, and lengthen the reach of long haul and metro dense wavelength division multiplexing networks by improving signal quality, the company said. The level of functionality and performance provided by these liquid crystal devices has generated significant interest in the marketplace over a very short period of time, said Doug Eccleston, business manager for Corning's Wavelength Management Products group. Expanding our manufacturing capabilities will enhance Corning's ability to meet the demand for product samples while supporting early adopters of the technology.
