Impact of Out-of-Band Noise on OSNR Measurement Using Brillouin Optical Spectrum Analyzer and Its Mitigation Method

Brillouin optical spectrum analyzer (BOSA) based on stimulated Brillouin scattering (SBS) can provide ultra-high resolution, which in theory can greatly improve the optical signal-to-noise ratio (OSNR) measurement accuracy, especially for systems with close channel spacing and cascaded filtering eff...
