We experimentally investigate the applicability of the conventional near-field patter (NFP), far-field pattern (FFP) and variable aperture (VA) methods for measuring the effective mode-field diameter (MFD) of the higher-order mode which can be used for evaluating the splice loss accurately. We confirmed that the variation in measured MFD values obtained with FFP and VA methods can be converged by...
We propose a new technique for characterizing single-mode operability by monitoring far-field patterns via a variable aperture. Both mode transmission performance and cut-off wavelength can be clearly evaluated independent of fiber structure.
