Single-mode propagation provides superior performance for long-distance applications because it allows for a single transmission path. This eliminates the dispersion and distortion that can occur when multiple modes are present in the fiber. Direct-line mode, step-index multimode, and graded-index multimode all allow for multiple transmission paths and therefore are not as well-suited for long-distance applications.
