Multimode Fiber

A Fiber with Core diameter much larger than the Wavelength of Light transmitted that allows many Modes of light to propagate. Commonly used with LED sources for lower speed, short distance links.

Some multimode fibers have a Core Diameter which is just somewhat larger than that for a single-mode fiber, but still much smaller than the Cladding diameter. Other fibers, called large core fibers, sometimes have a core which is hardly smaller than the cladding. These latter fibers can guide more light with poor beam quality, but for preserving the Beam Quality of a Light Source with higher Brightness it can be better to use a fiber with smaller core and moderate numerical aperture.
