This paper Analyze the comparative study of various lasers in free space optics by varying the distance. The fso data and distance limit are 2.5 Gbits and 1Km.The distance of fso increase using amplifier upto few km respectively. In this paper we are improve the these short coming by using wdm concept and transfer data 64x2.5Gbits on fso and compare results using DML and EML laser,it is also observed by using EDFA amplifier we can increase the Distance up to 25 Km with same data Rate. The work on suitability of various lasers like, directly modulated laser and Electro-absorption modulated Laser for an optical transmission link is evaluated. The results have been carried out by evaluating the value of Quality factor and BER at different values distance in km. It is found that using directly modulated laser; the signal can travel up to transmission length of 25 km with acceptable BER and Q factor. |
