Optical Communication with Time Division Multiplexing (OTDM) and Hybrid WDM/OTDM PON

Arpana Mishra ^[2] | Priyesh Mishra

Abstract: The high speed reliable data transmission is always required in communication. The passive optical network provides very high data rates for long distance. This work provides the performance of a four users Optical Time Division Multiplexing OTDM over different length of single mode fibers (SMF) for different bit rates. The effect of utilizing Erbium Dopped Fiber amplifiers (EDFAs) is investigated for mitigating effect of performance degradations due to attenuation. In order to increase capacity of the system, a hybrid four Wavelength Division Multiplexing WDM and four OTDM system has proposed. Dispersion Compensating Fiber (DCF) is used for reducing the effect of dispersion distortion. Post dispersion compensation is applied to a four users OTDM each with bit rate of 10 and 40 Gbps in terms of data capacity per Optical Network Unit (ONU). A bit rate of 160 Gbps is obtained from the work with a BER of 10-10 over length of 352.89km. The simulation has implemented using optisystem 7 and MATLAB R2011a.
