Low-loss single-mode-fibre splicing technique using core direct monitoring

Abstract

The axis offset error during single-mode-fibre axis alignment using core direct monitoring was studied. It has been found that the alignment performance is affected significantly by core eccentricity observation error due to the fibre cladding lens effect, and low-loss splicing of less than 0.1 dB can be achieved by the observed core eccentricity correction technique.
