Abstract
There is provided by this disclosure a method and apparatus for making fiber optic couplers that is comprised generally of the steps of stretching a fused optical fiber pair at a predetermined rate to produce first a tapered section, second a constant diameter cylindrical section, and third a final tapered section. The two optical fibers are placed in juxtaposition under a predetermined load, heated to a predetermined temperature until they fuse together to form a single entity having a predetermined width, length and circular cross section. The two moveable platforms apply a predetermined tensile load to the fibers and move the fibers past a heat source in a controlled manner to form the different sections.
