the achievement of a good reliability of optical cables has required high fiber strength. the surface treatment of preforms as well as drawing conditions used in order to realize this improvement are described. the fiber drawing has been performed using a graphite resistance furnace which can be operated with its top either closed or open. the contamination of fibers with particles produced by the furnace is explained for these two types of configuration. the results are expressed in terms of break frequency on a 10 km reference length, process defect origins and fiber length yields after proof testing at 0.9 percent and 1.5 percent elongation
