Low-Splice Loss Design of DS and DF Single-Mode Fibers

Dr C M Jadhao

Abstract: The Wavelength of zero first order chromatic dispersion can be shifted to the lowest loss wavelength for silicon fibers at 1.55 m to provide both low dispersion and low loss fiber. Dispersion-Shifted Single Mode Fiber achieves this. However, the design flexibility required to obtain particular dispersion, attenuation, and MFD, bend and Splice Loss characteristics has resulted in specific profile. An alternative modification of the dispersion characteristics of Single Mode Fiber involves the achievement of low dispersion window over the low loss wavelength region and allow flexible WDM i. e. Dispersion-Flattened Single Mode Fiber. The comparison of Splice Loss sensitivities of Dispersion-Shifted and Dispersion-Flattened Single Mode Fiber is analyzed. Since Splices are highly tolerant for longitudinal separation, transverse offset and angular tilt are considered. The comparative analysis shows that these losses are steady in Dispersion-Flattened Single Mode
