Abstract

Fiber optics have become a vital role in telecommunication technologies with many benefits, i.g. high speed transmission, non-electromagnetic interference and low energy consumption. An excellent single mode fiber (SMF) must provide a low attenuation and dispersion which occurs at same wavelength, i.e. 1550 nm. But, in silica based SMF, this property cannot be achieved in a bulk form. Meanwhile, the direct experiment is really not the best choice. Therefore, a simulation fiber design take a crucial role into account for obtaining zero dispersion shift. We design SMF geometry with zero dispersion by resizing the width of core and cladding. This design consists of inner and outer core-clad profile. We also provide several width boundaries for matching the lowest dispersion to the lowest attenuation in silica fiber-based. Moreover, the results shows that dispersion property of the design is suitable for long-haul optical communication systems.

Abstract

Birefringence characterization has been carried out for single-mode fiber (SMF) consisting of SMF-28, SMF-28e, SMF-28e+, SMF-28e+LL, and SMF-28ULL. The parameters that were varied were the refractive index of the core and the cladding, while the radii of both were equal to the wavelength of 1550 nm. Birefringence characterized by simulation can determine the quality of SMF by knowing the changes in the light propagation constant caused by polarized light on optical fibers. The simulation results show that in SMF-28ULL there is a propagation constant or birefringence which has a large influence compared to other types of SMF such as the magnitude of polarization and reducing power.
