Definition

single mode fiber

In optical fiber technology, single mode fiber is optical fiber that is designed for the transmission of a single ray or mode of light as a carrier and is used for long-distance signal transmission. For short distances, multimode fiber is used.

Single mode fiber has a much smaller core than multimode fiber.
