A0040A Optical Noise Analyzer Agilent Technologies and SYCATUS Optical frequency noise captured as power spectrum density 1/f noise, white noise and lorenzian linewidth analysis Investigation on ITLA for digital coherent transmission systems Optional integration with RIN / linewidth measurement functions SYCATUS provides a new solution of A0040A Optical noise analyzer for optical frequency noise measurement. A0040A enables to investigate the optical frequency noise as power spectrum density. The spectral purity of laser sources became the most critical concern along with the evolution of digital coherent transmission method. On the other hand, highly functional laser sources such as ITLA are facing the issue of optical frequency uctuations arising from EMI by integration with electronics or complicated control scheme. Optical Isolator (optional) Laser linewidth measurement is the traditional method for the evaluation of the spectral purity of laser sources. However, the laser linewidth is insufcient for the analysis of the constituent of optical frequency noise. The spectrum analysis is mandatory instead of laser linewidth measurement as DSP in digital coherent transmission systems has limited bandwidth for frequency offset compensation. A0040A Optical Noise Analyzer enables to capture optical frequency noise characteristics as power spectrum density by the combination of SYCATUS s unique method and Agilent X-series signal analyzer. SYCATUS Optical Noise Test Set Agilent X-Series Signal Analyzer SYCATUS A0040A Optical Noise Analyzer A0040A Optical Noise Analyzer is a powerful tool for investigating the cause of optical frequency uctuation with the ability of precise analysis of optical frequency noise characteristics of laser sources. A0040A extracts 1/f noise portion and white noise portion, which enables to derive lorenzian linewidth composed of only white noise. A0040A Optical Noise Analyzer optionally includes RIN measurement function and conventional laser linewidth measurement function. A0040A improves measurement convenience and investment efficiency as a totally integrated noise analysis solution for laser sources.
