Modeling for Ethernet Passive Optical Network Link

A behavior model for the communication link of Ethernet passive optical network (EPON) is presented. It consists of a fiber, a photodiode, a transimpedance amplifier (TIA) followed by a limiting amplifier and a clock and data recovery (CDR) circuit. Each part of the model is based on the architecture of its circuit to improve the model accuracy. The noise and jitter in each block is also considered. The performance of the system can be evaluated from the simulation of the behavior model. The simulation of the link is presented. Simulation results of the proposed model show a good agreement with experimental results. The complete behavior model can be useful in analysis of Ethernet passive optical network communication systems.
