Asymptotic solution to estimate single mode fibers splice reflection attenuation is proposed. The basis of calculation algorithm is approximation of splice zone by sectionally regular weakly guiding single model lightguides. A fiber waveguide Gaussian approximation to determine lightguide parameters of each section is applied. For model being investigated a generalization of known from the guiding system theory recursion solution for equivalent reflective coefficient is used. Model of splice of single model optical fibers and algorithm of calculation are described. The results of calculations being depended of mode field diameter range and length of splice zone for splice of optical fibers with typical parameters are performed.
