ABSTRACT:
The extent of loss produced in fibers due to the presence of OH infrared absorption bands is significantly reduced through the use of specific expedients during, for example, the preform collapse procedure. In particular, during this procedure a carbon tetrahalide composition is employed to essentially prevent the presence of any residual hydrogen-containing entity from influencing the quality of the preform and thus from influencing the quality of the fiber ultimately produced.
