DUBLIN -- Pilot Photonics, a privately held company producing optical comb subsystems for next generation optical transmission applications, will demonstrate their Optical Wavelength Comb Source (OWCS) at OFC/NFOEC 2013, booth #2309. The Pilot Photonics optical comb source is the only optical comb on the market offering tunable comb spacing. The source offers excellent stability and turnkey operation making it the ideal comb source for researchers investigating optical network systems at 400G and beyond. This optical comb is particularly relevant to designers of 400Gbps and 1Tbps transmission systems and will facilitate the creation of a stable testing environment. Pilot Photonics
