[Computer Science | Network | Transmission LossAttenuation, specifically in fiber optics, is the reduction in intensity of the light beam due to traveling through a transmission medium. The medium is typically a fiber of silica glass that confines the incident light beam to the inside of the transmission fiber. Attenuation is an important factor limiting the transmission of a digital signal across large distances. Attenuation is usually measured in dB/km because of the high quality of modern transmission media. 

Input variables:

  • `I` = Input Intensity
  • `O` = Output Intensity
  • Equation:
  • `10*log_10(I/O)`
