Passive Optical Networks - Introduction

Passive Optical Networks

Passive Optical Network (PON) is identified as a promising, high performance access solution. PON eliminates active electronic components between the signal paths and places passive components into the network to guide traffic based on splitting/routing optical wavelength(s) resulting in high bandwidth provisioning direct to the end users. There are multiple PON based architectures available in the literature out of which Time Division Multiplexing (TDM) based PON, Wavelength Division Multiplexing (WDM) based PON, Code Division Multiplexing based PON architectures are gaining interest of the research and deployment community. Under this project we provide a design for different campuses of the UET such as Kala-Shah Kaku and Faisalabad. In this design we propose dual ring hybrid WDM/TDM access architecture as shown in the figure. The following issues are being investigated in the project such as:

  • Designing, Dual-Ring based, passive optical network based access network
  • Wavelength Division Multiplexing and Time Division Multiplexing based network bandwidth management mechanisms
  • Handle critical issues of resilience & scalability both in increased number of users as well as in higher bandwidth demands at low cost.
  • Performing simulation to measure signal strength, Bit Error Rate (BER), power gain at different optical components in the network etc.
