Performance Analysis of Fiber Wireless Solution in Passive Optical/Copper Restrained Areas

Abstract

With the rapid rise of optical fiber access technologies, a new networking form is emerging called fiber-wireless (Fi-Wi). Wireless part is used where laying-out of fiber is not feasible economically and its operation and maintenance is problematic. Fi-Wi offers high quality and reliability, better coverage, high signal-to-noise ratio, low maintenance and less time required for deployment. In this paper, we have simulated Fi-Wi set up and analyzed QoS parameters offered by the solution. We have also compared its results with access network with fiber only (PON). The frequency range used for wireless portion of the system is 71-76 GHz (E-Band Frequency range). We have evaluated our simulation using variable data rates, diverse fiber lengths and varying optical launch powers and their impact on bit error rate (BER) and Q-factor. On the basis of simulation results, we conclude that Fi-Wi system gives comparable results in the last mile section against access network based on PON or Copper.
