Optical fibers exhibiting high mechanical reliability are the result of strength optimization of the fibers and of the fusion splices necessary to join them. High-strength fibers have progressed from short-length research grades to large quantities of long-length fibers prepared in a production environment. In addition, fusion splices can now be made with strengths equivalent to the as-drawn fiber to extend the achievable length of high-strength fiber even further. This paper summarizes recent published results and discusses the salient features and techniques of the more promising methods and processes for producing multikilometer lengths of spliced fiber.
