Abstract

Diffusion processes in thermally diffused expanded-core (TEC) of single mode telecommunication fibers areas, at temperatures t=1900°C ÷2000°C were presented in the paper. The loss of TEC areas of thermally connected telecommunication fibers of different types (G.652 and G.655) in above mentioned temperatures of splicing was theoretically analyzed and counted. In the analysis the loss resulted from the mismatch of mode fields of connected fibers and at the same time the mismatch of the dimensions of transit areas were taken under consideration. Presented analysis allows, assuming the knowledge of the values of core dopant diffusion coefficients, the temperature and the time of splicing, to predict the loss of splicing of different types telecommunication fibers. Consistence of the theoretical calculations with experimental data of thermal connected telecommunication fibers with significantly different parameters, was proved.
