Design and Simulation of Hybrid WDM/TDM Passive Optical Network

Abstract

Due to the expansion of internet and multimedia services, such as Passive Optical Network (PON) come to the forefront of the research field. Network service provider mostly deploy Time Division Multiplexing (TDM) based PON because it is cost effective. The main limitation with TDM-PON is its limited bandwidth. So in order to provide increased bandwidth Wavelength Division Multiplexing (WDM) based PON is used. But the main limitation with WDM-PON is its high cost. Therefore the advantages of TDM-PON and WDM-PON mitigate with each other and we propose the architecture of hybrid WDM/TDM PON. In this paper, we evaluate the performance of hybrid WDM/TDM PON in terms of Q-factor and Bit Error Rate (BER).

Evaluation of 1 Tbit/S WDM-Oil-TDM-Pon Performance on 28 GHZ Frequency Band

“…A WDM-OTDM architecture with increase efficiency and throughput while reducing delays and errors is presented in [1]. V. Lohani and R. S. Prasad [3] studied the performance of the WDM-TDM hybrid system in the presence of an optical amplifier to increase the maximum number of users to 320 users up to 160 km with a data rate of 1.25 Gbit/s. In [4] Amritpal Singh and al.proposed a bidirectional hybrid PON with a downstream signal of 10 Gbit / s and a modulated upstream signal of 5 Gbit / s supporting 8 ONU over a transmission distance of 45 km.…”

“…Parameters of the components located between the OTDM transmitter and the OIL module included are listed in Table 1. 193.1 THz Frequency [1] 193.2 THz Frequency [2] 193.3 THz Frequency [3] 193. Reception block settings are listed in Table 3.…”

Simulative Analysis of Bidirectional BPON System at Low Insertion Losses and Attenuation

“…The three main function units in which PON depends are central office(CO),remote node(RN),optical network unit(ONU).OLT(optical line terminal) is placed on CO which transfer the data from access node to ONU though a RN. The passive components are applied in RN, it does not needed a power [2].…”
