Optical Power Budget Calculator

Calculate Maximum Fiber Optic Link Length

Given an optical transmitter and receiver set, the most important question concerning a system designer or integrator is the maximum implementable link length.

To use the Optical Power Budget Calculator select a launch power and receiver sensitivity, then enter values for other required information (Link Length, Number of Patch Points, etc.)

  1. Attenuation over Corning SMF 28 Single Mode Fiber
  2. Reserve sensitivity should ideally be > 3dB. Less conservative safety factors may be acceptable as per the system engineer.
