Abstract
Official abstract text for this publication.
In aligning ends of optical fibers, e.g. for performing a prealignment of ends of large mode area double-clad fibers (LMA-DCFs) in order to thereafter perform a core alignment process, in a fiber optic fusion splicer a best, optimum or near optimum position or setting of the optical system for observing the self-focusing effect is first determined and then the very alignment operation may be performed using the determined setting. The very alignment process may then be performed by adjusting stepwise the offset distance between the observed fiber ends by e.g. using a cascade technique.
First claim
Opening claim text (preview).
The invention claimed is: 1. A device for splicing two optical fiber ends to each other comprising: fixtures, each fixture holding one of the two optical fiber ends so that longitudinal directions of the two optical fiber ends are substantially parallel to each other, motors connected to the fixtures for moving the fixtures and thereby the two optical fiber ends, electrodes for producing an electric arc between points of the electrodes, the electric arc heating regions of the…
