Receiver noise includes thermal noise, dark current noise, and quantum noise. Noise is the main factor that limits receiver sensitivity. OSNR for each level and for complete signal can be defined The signal at the output of an optical amplifier in response to a noise free signal at the input is The following formulation accounts for. They include the following: Because the intent of this chapter is to discuss optical detector and receiver properties, only noise associated with the photodetection process is discussed. Once we have. This chapter attempts to provide a simplified interpretation of the meaning of “noise,” present its underlying theories, and enumerate various noise sources that contaminate the optical signal. In communication systems, where electrical, radio or optical signals are transmitted; noise can be viewed as an impairment resulting in the degradation of the information contained in the signal [1,7]. Optical amplifiers can be used.
