singlemode fiber

(redirected from Single-mode fiber)

singlemode fiber

An optical fiber with a core diameter of less than 10 microns. Used for high-speed transmission over long distances, it provides greater bandwidth than multimode, but its smaller core makes it more difficult to couple the light source. Increasingly, singlemode fiber is used for shorter distances. When singlemode fiber is used in shorter distances, such as a campus or metropolitan area network (MAN), step-index fiber is used. For longer distances and for transmitting multiple channels (WDM), dispersion-shifted fiber is used. Contrast with multimode fiber. See dispersion-shifted fiber, step-index fiber, dispersion and fiber optics glossary.

Distributed feedback (DFB) and Fabry-Perot (FP) lasers are expensive relative to light-emitting diodes (LEDs) and vertical-cavity, surface-emitting lasers (VCSELs), but the high-power and highly focused source beam allows efficient coupling of high power levels into the small core of single-mode fiber.
