In this paper we investigate several silica-based suspended core microstructured fibers optical (SC-MOFs) in regards to providing the high efficiency coupling for broadband dispersion measurement. We present free-space optic and butt coupling setup capable of coupling signal from standard single mode fibers (SMF) into SC-MOF with core diameter of less than 4 μm and coupling efficiency over 50%. We then investigate SC-MOF’s effective mode area, nonlinearity coefficient and chromatic dispersion curve, using both modeling of the fibers and measurements. Lastly, we have investigated the effects of the aspheric lens on broadband coupling for the chromatic dispersion measurement.
