ABSTRACT:
A method for splicing fiber optic cables to each other utilizes a splice tube of a glass material having a passage extending through it. A technician inserts ends of each optical fiber into the glass tube and abuts the ends of the fibers against each other. The technician applies a vacuum to the passage and heat to the glass tube. The heat softens the glass tube, and the reduced pressure in the passage draws the side walls of the glass tube tightly around the optical fiber ends.
