Passive Optical Network System Performance Analysis Using a 10 Gbit/s DML
2014
As a promising technology for broadband communication, Passive Optical Network (PON) has been deployed to support the communication in smart grid system. This paper theoretically analyzes the influences on Directly Modulated Laser (DML)-based PON system performance including Bit Error Rate (BER) and power budget. First, we establish the DML-based PON system model, and then the system performances are simulated under different linewidth enhancement factor, received optical power and fiber length. Simulation results show the increase in received optical power to maintain a given BER due to fiber nonlinearities. This research provides a theoretical guidance on the PON system design.
