Preparation of Optical-Fiber Ends for Low-Loss Tape Splices

Abstract

We describe a reliable method of preparing planar fiber tape ends by fiber fracture. Using this technique, with suitable precautions to preserve cleanliness during splice preparation, we have measured a splice loss of less than 0.26 dB in 99 percent of all attempts.

A Molded-Plastic Technique for Connecting and Splicing Optical-Fiber Tapes and Cables

“…12 We believe, however, that the technique described in this paper has a potential for adaptation to a variety of fiber-connector problems and to field splicing of fiber cables.…”

“…This can conveniently be done by using the device described in Ref. 12. The theory of glass fracture under these conditions is derived in Ref.…”

“…Cherin 10 used embossed grooves and devised a jig for inserting tapes with previously prepared fiber ends into these grooves. The lowest losses in splices based on this technique were obtained by Chinnock et al, 12 who prepared the ends of the fibers using a fiber-fracture technique. 7 All these methods, how ever, have drawbacks resulting either from difficulties associated with the preparation of the fiber ends or with the mechanical align ment of the previously prepared ends.…”

Photons in Fibers for Telecommunication

“…The splicing of an entire tape array of fibers has been accomplished in a single step by aligning the fibers in an embossed chip and sealing them with epoxy glue (29).…”
