BaySpec Incorporated, founded in 1999 and based in Fremont, California, designs fiber optic components and subsystems for businesses across the optical networking and telecommunications industry. The firm develops proprietary Fiber Bragg Grating (FBG), dense wavelength-division multiplexing (DWDM), erbium doped fiber amplifier (EDFA), and optical channel performance monitor (OCPM) photonics devices that optimize enterprise, metro, short-haul, and long-haul network performance. The company is known for its Volume Phase Grating, or VPG (TM), technology. It provides customers with the IntelliGuard (TM), WaveCapture (TM), Chromatica (R), IntelliGain (R), and IntensiGain products. IntelliGuard OCPMs collect wavelength, power, and optical signal-to-noise ratio (OSNR) 25/50/100GHz channel data. The systems include a 512-element detector array. WaveCapture is an FBG analysis system. Chromatica 100GHz DWDM multiplexers and demultiplexers include athermalization, wide passband, and other features. Chromatica products comply with Telcordia GR-1209/1221 requirements. IntelliGain and IntensiGain EDFAs include low noise, high output, and low power consumption features. BaySpec has received funding from Intel (R) Capital, Broadview, CDIB Ventures, Cisco, H&Q Asia Pacific, and Finisar Corporation. The company was acquired by Finisar in 2002. Finisar, based in Menlo Park, California, is listed on NASDAQ under the FNSR symbol. BaySpec was founded by Dr. William Yang.
