Fusion splices for optical fibers by discharge heating
TLDR
A new type of electric discharge fusion splicing apparatus for optical fibers offering several advantages is developed and evaluated, and Mechanical strength of the splice is also excellent.Abstract:
A new type of electric discharge fusion splicing apparatus for optical fibers offering several advantages is developed and evaluated. An average splicing loss of 0.10 dB is obtained for step-index multimode silica fibers with a 60-μm core diameter. Tolerances in discharge energy, fiber misalignment, compression force and stroke length during fusion, and end face conditions are discussed experimentally. No accurate fiber axis adjustment is necessary in this apparatus. Mechanical strength of the splice is also excellent.read more

Fusion splices for single-mode optical fibers
TL;DR: In this paper, a low-loss splicing method based on discharge fusion for single-mode fibers was developed, and it was found that the optimum heating temperature for low loss splices is near 2000°C at 8.5 W electric discharge power.
Journal ArticleDOI
Cut-off wavelength measurements for single-mode optical fibers.
TL;DR: It is found that the first higher-order mode under the condition near cut-off rapidly attenuates because of waveguide imperfections, in which the loss due to core-cladding boundary distortions is the most dominant.

Single-mode systems and components for longer wavelengths (Invited Paper)
TL;DR: In this article, the advantages of single-mode optical fiber transmission technology in the 1.0-1.8-m wavelength region are reviewed and the advantages and progress in fibers, fiber splicing, and devices are discussed.

Arc-fusion splicing of single-mode fibers. 1: Optimum splice conditions.
TL;DR: A narrow, quick fusion method, where the fiber-fused region is restricted by the narrowing of the electrode gap and the arc-discharge time is short compared with the conventional multi-mode fiber splice, is presented that will reduce the surface tension effect.

Apparatus for fusion splicing of optical fibers
TL;DR: In this article, a fiber gripping head has been used to hold a coated portion of a fiber and a spring loaded portion for bearing on a stripped portion of the fiber end, and the second portion is deflectable relative to the first portion.

Simple, low-loss joints between single-mode optical fibers
TL;DR: Low-loss joints between singlemode optical fibers have been made without microscopic alignment, without fusing the tips, and without monitoring the transmitted power while the joints are assembled as discussed by the authors.
