WebOSNR is the short form of Optical Signal to Noise Ratio. It is key parameter to estimate peformance of Optical Networks. It helps in BER calculation of Optical System. As per … WebShot noise or Poisson noise is a type of noise which can be modeled by a Poisson process. In electronics shot noise originates from the discrete nature of electric charge. Shot noise also occurs in photon counting in optical devices, where shot noise is associated with the particle nature of light.
