M

A fiber with a large enough core diameter can support light in many different modes and each mode will follow a slightly different path through the core. This leads to dispersion between the different mode, which limits the distance over which a signal can be transmitted while remaining intact, but it also makes the power density more diffuse that raises the damage threshold of the fiber.
