Abstract

In this paper a discussion on the design of single-mode mid-IR optical fibers operating in the 2-5 μm wavelength range for use in repeaterless telecommunication systems is made. First, the different factors affecting the single-mode fiber design are identified and then applied to the mid-IR materials case. Then, theoretical evaluations are made for the chromatic dispersion, both material and waveguide, and the excess losses caused by microbending, macrobending and fiber splicing, for several single-mode step-index fiber structures having different fluoride-glass compositions. Optimum fiber parameters such as material composition, core and cladding diameters and relative index difference are obtained based on these evaluations which lead to various fiber designs either from the minimum dispersion or the minimum loss point of view, or a tradeoff between these two.
