The propagation of light through a multi-mode optical fiber. A laser bouncing down an acrylic rod, illustrating the total internal reflection of light in a multi-mode optical fiber. Fiber with large core diameter (greater than 10 micrometers) may be analyzed by geometrical optics.
The equipment used for communications over multi-mode optical fiber is less expensive than that for single-mode optical fiber. [1] Typical transmission speed and distance limits are 100 Mbit/s for distances up to 2 km (), 1 Gbit/s up to 1000 m, and 10 Gbit/s up to 550 m.
In fiber-optic communication, a single-mode optical fiber (SMF), also known as fundamental- or mono-mode, [1] is an optical fiber designed to carry only a single mode of light - the transverse mode. Modes are the possible solutions of the Helmholtz equation for waves, which is obtained by combining Maxwell's equations and the boundary ...

The input facet of a multimode fiber is placed at the lens focus such that the various spectral components are coupled into different fiber modes. The figure inset illustrates how different spectral components are coupled into and propagate in the multimode fiber. The dashed line represents the optic axis of the fiber.
It defines identification schemes for fibers, buffered fibers, fiber units, and groups of fiber units within outside plant and premises optical fiber cables. This standard allows for fiber units to be identified by means of a printed legend. This method can be used for identification of fiber ribbons and fiber subunits.
A cladding mode is a mode that is confined to the cladding of an optical fiber by virtue of the fact that the cladding has a higher refractive index than the surrounding medium, which is either air or the primary polymer overcoat. [5] These modes are generally undesired.
Optical fiber connectors used for PM fibers are specially keyed so that the two polarization modes are aligned and exit in a specific orientation. Note that a polarization-maintaining fiber does not polarize light as a polarizer does. Rather, PM fiber maintains the linear polarization of linearly polarized light provided that it is launched ...
