Performance Analysis of Optical Transmitter with the Single Mode Laser

Abstract

During these days, optical fiber networks are widely used in telecommunication for transmitting the signal or information from one corner to another corner in the world. The efficiency of optical fiber networks deteriorates due to several limitations like attenuation, dispersion, non-linearities, fragility of fiber and other losses. So for the effective and successful communication it is important to reconsider about how optical signal is transmitted; what amount of this signal is transmitted and what distance is covered by the signal through the fiber. The non-return to zero technique based optical communication system with single channel over single mode fibre is investigated in this simulation process. On the basis of modulated outputs of NRZ technique, a comprehensive comparison is developed in terms of Quality factor and bit error rate (BER) , histogram and peak current of single mode laser  to establish the merits and demerits of the network system in short as well as long haul optical transmission system. Finally, it is to be investigated the performance analysis of optical transmitter for the given fiber length with the effect of peak current of single mode laser improved by OptiSystem 19.0.
