TRANSMISSION CABLE OPTICAL FIBER PROTECTOR AND METHOD

摘要

A fiber optic transmission cable fiber protector includes a splice tube positioned over the ends of a pair of fiber optic cables having an outer capillary tube containing at least one optical fiber within an inner capilla ry tube. The optical fiber protector includes a pair of optical fiber strain relief mechanism positioned near the ends of the optical fibers; the strain relief mechanisms are captured within a heat sink tube that is inserted into each end of the outer capillary tubes. The splice tube is welded to the oute r capillary tubes. Heat generated by the welding process dissipated by the hea t sink and gases generated during the welding process are vented through a hol e in the outer capillary tube into the optical fiber splice area. In an alternate embodiment a weld coupling is welded to each end of the splice tub e and is further welded to the outer capillary tubes. A sealing mechanism is positioned on the inner capillary tubes within the outer capillary tubes forming a seal therebetween.
