Longitudinal sections of fused splices of different telecommunication single mode fibers were prepared and examined by scanning electron microscopy (SEM). Splices were examined for diffusion of dopant elements and for the presence of an intermediate zone. Observations in the material contrast mode obtained with backscattered electrons and X-ray microanalysis with the use of an energy dispersive spectrometer...
Measurements of NZDA-SMF fiber parameters of the TrueWave Ž and LEAF type adjusted to wave multiplexing have been presented. The results of optimization of fibers splicing conditions have been shown, as measurements of loss and mechanical strength of non-optimized and optimized splices. The calculation results of diffusion coefficient of GeO2 dopant diffusing from the core to the cladding during the...
