Method of re-connecting optical fibers and system

Abstract

The present invention relates to a method of re-connecting a first optical fiber () with a second optical fiber (), the first fiber () and the second fiber () each having a plurality of outer cores, comprising: (a) positioning a first end section of the first fiber () and a second end section of the second fiber () in proximity so as to be aligned with one another along a longitudinal axis of the first and second end sections in a current connection position including a current connection orientation, in which a current relative rotational angle between the first and second end sections about the longitudinal axis is not known with respect to a relative rotational angle between the first and second end sections in a registered connection orientation determined with respect to a coordinate system during a previous connection of the first fiber () with the second fiber (); (b) optically interrogating the outer cores of the first and second fibers () through the current connection position to receive optical signals from the outer cores; (c) modifying, from the optical interrogation of the outer cores, the registered connection orientation such that the first and second fibers in the current connection orientation including the current relative rotational angle between the first and second end sections about the longitudinal axis are correctly registered with respect to the coordinate system.
