TECHNOLOGICAL IMPERFECTIONS OF FORCE ROD GEOMETRICAL PARAMETERS FOR PANDA OPTICAL FIBERS PRODUCTION

The paper deals with the dependence in radial dimensions changes of the workpieces on the angular coordinate based on experimental data about the geometry of the cross-sections of force rods batch for the production of anisotropic Panda-type optical fibers. An algorithm of geometrical parameters s...

the biggest deviation from the round profile (up to 10%) is fixed on the border between the alloyed core of the force rod and the external layer of the pure quartz
whereas the deviations on other borderlines are negligible (a tenth hundredth of a percent). It is determined that within this technological process the non-circular cross-sectional shape of alloyed core is realized
which can be called “faceting” for convenience (with three “faces” of different length). The following long control of the cross-sectional shape of the force rods has proved the results recurrence.
