Optical Time Division Multiplexing (OTDM) and Hybrid WDM/OTDM PON Performance Investigation

Husam Abduldaem Mohammed

Every day, the need for high speed reliable data transmission increases more and more. One important option is the passive optical networks which use the optical fiber and provides high data rates and long distance. This work investigates 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 Eribium Dopped Fiber amplifiers EDFAs was 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 was proposed Dispersion Compensating Fiber DCF was used for reducing the effect of dispersion distortion. A post dispersion compensation was applied to a four users OTDM each with bite rate of 10 and 40 Gbps in terms of data capacity per Optical Network Unit ONU. A bit rate of 160 Gbps was obtained from the work with an BER of 10-10 over length of 352.89km. The simulation was implemented using optisystem 7 and matlab R2011a.
