Study of the Bidirectional PON Performance Based on the Optisystem

Abstract:

This paper presents the background of PON (Passive Optical Network), introduces the powerful communication design and simulating software which named Optisystem, show the PON(Passive Optical Network) theory and structure, designs the PON fiber link which has 1310nm uplink wavelength and 1490nm downlink wavelength and then analyses the models performance. In the software, we set up a rate of 1Gbps model of PON by using the component in the Optisystem. Through calculating the model, the document gets the spectrum figure of the simulate fiber link, and analyses the parameter, such as spectrum character, Q factor, eye diagram and BER, the result verified the validity and practicable of the models design, makes the result that the initial character fiber link cant meet the demand of optical communication, so changing the transmission distance to 10 km , transmitter power to-1dBm, meeting and obtaining the basic requirements of the system performance, after that the paper comparing the coding between none return to zero (NRZ) and return to zero (RZ) encoded mode, the eye diagram analyzer component show that NRZ code is better than RZ code, in the end of the paper there is the conclusion.
