ABSTRACT:
Thermally dissimilar glass fibers are fusion spliced by pretreating the cleaved end surface of the high-temperature fiber to provide a smooth surface for making good contact with the low-temperature fiber. The fibers are heated to a temperature that is high enough to soften the low-temperature fiber but not the high-temperature fiber and brought in contact to form the fusion joint.
