Flexible casing for optical ribbons

摘要

A rectangular flexible casing for holding optical fiber ribbons has an inner tube made of low friction material, an outer tube, and flexible tensile fibers between the inner and outer tubes. A vacuum sizing device is used in the manufacture of the inner and outer tubes to shape the tubes and to maintain their dimensional stability. The casing may be used to protect portions of optical fiber ribbons passing from a cable to a connector to complete a connector assembly.
