The connection component comprises a plurality of optical fibers united at a common end in such a manner that their claddings are mutually tangential and the axes of their cores occupy a configuration that corresponds to the configuration of the axes of a multi-core with which said common end is to be connected, said fibers being free from one another at their opposite ends. The method brings the fibers together by depositing a drop of liquid thereon.

Component for connection to a multi-core fiber, and a method of

The invention relates to apparatus for identifying and splicing at least one multicore optical fiber and including both a system for displaying each multicore fiber and a fiber splicing system. According to the invention at least one ring for surrounding each multicore fiber to be spliced has an outside envelope that is homothetic (geometrically similar) in shape to the outer envelope of each multicore optical fiber, with the outer outside envelope of each ring being designed to be marked as a function of analysis of the image of each multicore fiber as obtained by means of the display system.

Apparatus and a method for identifying and splicing multicore fibers

This invention concerns a method for connecting optical fibres, comprising stages consisting in (i) effecting a controlled rough polishing of the interface (5) of the fibres (1) to be connected, (ii) steeping the ends of the fibres (1) in a concentrated solution hydrofluoric acid and (iii) aligning then connecting the fibres (1) using an index matching material (FIG. 4). The invention also concerns a variable optical attenuator and a system using this attenuator to measure the effect of the reflection coefficient on an optical line.
