Abstract: A new method for alignment of asymmetric polarization-maintaining (PM) fibers has been developed. It improves alignment accuracy for PM fibers with asymmetric stress applying parts. It provides a fast and accurate universal method for splicing recently developed PM fiber types.

Abstract: The recently released Fujikura PCS-100 is a novel stripping tool for removing polyimide coating from optical fibers. Extensive testing on the stripping ability of this equipment has demonstrated repeatable high tensile strength values with narrow distributions, both for polyimide and acrylate-coated optical fibers. Additionally, the PCS-100 stripping process has been shown to create an evenly beveled coating edge, ideal for applications that include recoating.

Abstract: A novel feedback control method has been developed for an automated splicer using a CO2 laser as the heating element. The feedback method employs a sensor for laser beam power and CMOS cameras as sensors for fiber luminescence which is directly related to glass temperature. The CO2 laser splicer with this type of feedback system provides a consistent platform for the fiber laser and bio-medical industry for fabrication of fused glass components such as tapers, couplers, combiners, mode-field adaptors, and fusion splices. With such a closed loop feedback system, both splice loss and peak-to-peak taper ripple are greatly reduced.

Abstract: A novel method for aligning multi-core fibers (MCF) provides a systematic approach for MCF splicing in the lab, in cable factories, and in the field. This method also provides possibility of loss estimation for side-cores using IPA method and central core with WSI images.

Abstract: A novel arc calibration method has been developed for fusion splicing optical fibers with a large variety of glass diameters. This method heats the fiber with multiple short arcs and measures the amount of meltback at the corner of the fiber-ends. The fiber corner melting speed is found to be proportional to the fiber temperature. By varying the arc power of the multiple arcs, we can determine the desired arc power and appropriate melting speed for the tested fiber. This method has tested to be consistent and accurate using a newly released splicer with a controllable plasma zone. The splicer can automatically select the correct arc power for various fiber glass diameters. It enables the optimized splice parameters to be easily transferred to multiple splicers in production lines, resulting in consistent, high quality splice results.
