Fibers that carry more than one mode are called multi-mode fibers. There are two types of multi-mode fibers. One type is step-index multi-mode fiber and the other type is graded-index multi-mode fiber.

As the core of the fiber is so small that one ray of light at an angle of 0 ° incident can stably pass through the fiber length, without much loss, this type of fiber called single-mode optical fiber. The basic requirement for single-mode fiber is that the basic limit small enough to transfer to a mode of singing. This lowest order mode can propagate in all fibers with small cores (as long as light can be physically fibers).
