"WebIn multimode fiber, light is carried over a number of different paths, or modes. An ideal graded index multimode fiber will compensate for the different path lengths by slowing down the modes that travel in shorter paths near the center of the core (figure 1, red), while allowing light that travels further (figure 1, green) to move more quickly.
