Abstract

According to this invention, a coupler or coupling tool is proposed with active alignment of one fiber with respect to another in both planes of interest, i.e. the vertical position and the lateral position. A key feature of the alignment means is that as one position is adjusted slightly, the other position is automatically adjusted through full range. This is accomplished rapidly enough that it is simple to test all combinations of the two positions.
