NOISE IN FIBER OPTIC COMMUNICATION LINKS robert dahlgren ABSTRACT The physics of NOISE in optical COMMUNICATION LINKS is of great interest in the design of FIBER OPTIC COMMUNICATION systems. In this report the role of NOISE in optical communications, and how it can limit the performance of optical communications systems, will be examined. The origins of NOISE in the various optical and analog electronic components will be discussed, and a methodology for a NOISE budget will be proposed. The ramifications of Signal-to- NOISE Ratio (SNR) are of fundamental importance and considerable effort will be spent attempting to bound the SNR requirement for a given set of system requirements. Many of the types of NOISE we will be dealing with may be approximated as white and/or Gaussian, which permits mathematical simplification without any loss of rigor, to the extent that the approximations are valid.
