Interference effects in optical fiber connections.
Optical interference may occur in fiber connections, and this can have an important effect on transmission loss. A theoretical analysis shows that the effect occurs in both single-mode and multimode fibers and depends on fiber end face separation, the source spectrum, and the modal power distribution in the fiber. Experimental observations of interference in dry multimode fiber connections confirm the analysis for both laser diode and LED sources.
