Abstract : This work presents some characteristics for both single- and multimode fibers, sucb as butt-coupling efficiency, cigenmodes, and macrobending effects . Two step-index. single-mode fibers with different core radii, 5 and 8,3 urn, are characterized. The coupling efficiency in the fanner is close to 96% for singlernode veSEL with beam spot size of 3 urn and depends on the injection current. The second type supports two modes and the coupling efficiency decreases to 86%after using a simple filter consisting of a fiber loop with] 2. mrn diameter and 5 windings for removing the higher order lP I I mode by macrobending effects. The results show that the coupling efficiency in gradedmultirnidc fibers has radial tolerance wider than that of singlcmode fibers and has a maximum value of 81%,
