Abstract

This paper presents both the theoretical and experimental results of the performance characterization in the emerging technology of stub fiber connectors. A stub fiber connector, consisting of two closely spaced joints, shows negligible modal noise. However, modal interference at such a connector joint results in a wavelength dependent oscillations in insertion loss. It is shown that this phenomenon is strongly affected by the cutoff wavelength of the stub fiber and the losses at both joints. Amplitude of the loss oscillations depends on each joint loss and on the polarization angle between the two interfering beams. A measurement method is also presented to characterize the insertion loss of such connectors.
