Also called monomode fiber. Single-mode fiber has a narrow core that allows light to enter at only a single angle. Such fiber has higher bandwidth than multimode fiber, but requires a special light source with a narrow spectral width (for example, a laser).
SMF) A type of fiber that uses a single path for light transmission (i.e. the light is not reflected within the core). Single-Mode supports greater distances than multi-mode. Typically, Single-Mode fiber may support distances from between 2Km up to 20Km. The distance supported is a factor of the loss budget of the cable vs. the power budget of the Single-Mode transmitter.
Fiber-optic cabling with a narrow core that allows light to enter only at a single angle. Such cabling has higher bandwidth than multimode fiber, but requires a light source with a narrow spectral width (for example, a laser). Also called monomode fiber. See also multimode fiber.
An optical fiber whose core is sufficiently narrow that only one waveguide mode can propagate.
An optical waveguide (or fiber) in which the signal travels in one mode. The fiber has a small core diameter, typically 8.3 µm.
An optical fiber that supports only one mode of light propagation above the cutoff wavelength.
A very thin fiber-optic cable which allows only one mode (light ray) to pass through it. Single-mode fiber supports long transmission distances and high data rates.
An optical glass fiber that consists of a core of very small diameter. A typical single-mode fiber used in CCTV has a 9 mm core and a 125 mm outer diameter. Single-mode fiber has less attenuation and therefore transmits signals at longer distances (up to 70 km). Such fibers are normally used only with laser sources because of their very small acceptance cone.
An optical waveguide (or fiber) with a small core diameter in which only a single mode is capable of propagation. This type of fiber is particularly suitable for wideband transmission over large distances, since its bandwidth is limited only by chromatic dispersion.
An optical glass fiber that consists of a core of very small diameter. A typical single-mode fiber used in CCTV has a 9-µm core and a 125-µm outer diameter. Single-mode fiber has less attenuation and therefore transmits signals at longer distances than multimode fiber.
Optical fiber designed for 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. See also MMF.
A small- core optical fiber through which only one mode will propagate. The typical diameter is 8-9 microns.
