How ever,in long haul communication the problems of attenuation ,dispersion,bending lose etc become very important as they limit the transmission of information data. In this work we have been reported the optimum optical wave length for communication for a single mode ber with core radius 4 m; 5 m; 25 m and 50 m with refractive indices for core n1 = 1:48 and for cladding n2 = 1:46. Further more the varation of normalized V-parameter with wave length has been reported. It has shown that optimum wave length of transmission for these bers is 1550nm KeyWords:single mode ber;cuto frequency;laser light;wave length;Optical ber lossesKeyWords:single mode ber;cuto frequency;laser light;wave length;Optical ber losses viiThesis
