Optical power budget and cost estimation for Intelligent Fiber-To-the-Home (i-FTTH)

This paper calculates the optical power budget and power margin for designing a conventional passive optical network (PON)-based Fiber-To-the-Home (FTTH) and Intelligent Fiber-To-the-Home (i-FTTH) with different link length of drop fiber and optical power splitting ratio of 1×N passive optical splitter. A simple calculation is used to determine how much loss and power are available for each individual fiber link in both networks with different type of signals. The cost estimation for both networks including the additional optical monitoring, switching, and protection systems are calculated and compared.
