Multimode Fiber
Laser coupled with multimode fibers is widely used in many fields due to its high capacity and reliability. Because multimode fibers have a larger core diameter that supports multiple propagation modes, they are limited by modal dispersion. However, on the other hand, the larger core diameter also means they are better at collecting light than single-mode fibers, and due to modal dispersion in the fibers, multimode fibers also have a higher pulse propagation rate.
