Abstract

In this work diffusion processes in thermal connected cylindrical fibers with weakly guiding and circular cross-section, that is telecommunication fibers, have been presented. There have been discussed diffusion distributions of the core dopant of fibers spliced in t ≈ 2000^o C. Gaussian approximations of the core dopant concentration distribution and refractive index in the connecting area of single mode telecommunication fibers have been presented. Theoretical analysis of propagation and loss characteristics for thermally diffused expanded-core (TEC) of single mode telecommunication fibers has been performed, as well. Consistence of theoretical calculation results with experimental data, achieved on the basis of connecting telecommunication fibers with significantly different parameters, has been proved.
