Abstract :
Modal noise has been observed in overmoded short fibre sections and transmitter pigtails resulting in performance degradation in a single-mode-fibre transmission system. The power penalty becomes negligible when the fibre is sufficiently long or is deployed with a bend to sufficiently attenuate the LP11 mode.
