All-silica fiber, also called all-glass fiber or silica-silica fiber, is an optical fiber whose core and cladding are made of silica glass. The refractive index of the core glass is higher than that of the cladding. The cladding of an all-silica fiber should not be confused with the polymer overcoat of the fiber. ...more on Wikipedia about "All-silica fiber"
Dispersion shifted fiber, specified in ITU-T G.653 and also called DSF, is a type of single-mode optical fiber that has had dopants added which shift the zero-dispersion wavelength from the natural 1300nm in silica-glass fibers to the minimum-loss window at 1550nm. This is advantageous because it allows a communication system to suffer low dispersion and low attenuation. However, when used in wavelength division multiplexing systems, dispersion shifted fiber suffers from four-wave mixing which causes intermodulation of the independent signals. As a result nonzero dispersion shifted fiber is now deployed rather than DSF. ...more on Wikipedia about "Dispersion shifted fiber"
In fiber optics, a doubly clad fiber is a single-mode optical fiber that has two claddings. This is also called depressed-inner-cladding fiber, and W-profile fiber (from the fact that a symmetrical plot of its refractive index profile superficially resembles the letter W). ...more on Wikipedia about "Doubly clad fiber"
In telecommunications, a graded-index or gradient-index fiber is an optical fiber whose core has a refractive index that decreases with increasing radial distance from the fiber axis (the imaginary central axis running down the length of the fiber). ...more on Wikipedia about "Graded-index fiber"
Multi-mode optical fiber (multimode fiber or MM fiber) is a type of optical fiber mostly used for communication over shorter distances, e.g. within a building. It can carry 1 Gbit/s for typical building distances; the actual maximum speed (given the right electronics) depends upon the distance. It is easier to connect to than single-mode optical fiber, but its limit on speed x distance is lower. Multi-mode fiber has a larger center core than single-mode fiber, which allows it to support more than one propagation mode, or path within the fiber. ...more on Wikipedia about "Multi-mode optical fiber"
Nonzero dispersion shifted fiber, specified in ITU-T G.655 and also called NZDSF, is a type of single-mode optical fiber which was designed to overcome the problems of dispersion shifted fiber. NZDSF is available in two primary flavors, NZD+ and NZD-, which differ in their zero-dispersion wavelength which is typically around 1510nm and 1580nm respectively. Because the zero-dispersion point of NZDSF exists outside of the normal communications window, the effects of four-wave mixing and other non-linear effects are minimized. Other types of NZDSF include RS-NZDSF which has a reduced slope in its change of dispersion and large core NZDSF which further reduces residual non-linear distortion under high launch power. ...more on Wikipedia about "Nonzero dispersion shifted fiber"
An optical fiber (or fibre) is a transparent thin fiber, usually made of glass or plastic, for transmitting light. Fiber optics is the branch of science and engineering concerned with such optical fibers. ...more on Wikipedia about "Optical fiber"
Photonic-crystal fiber (PCF), also spelled fibre, is a new class of optical fiber based on the properties of photonic crystals. Because of its ability to confine light in hollow cores or with confinement characteristics not possible in conventional optical fiber, PCF is now finding applications in optical communications, fiber lasers, nonlinear devices, high-power transmission, highly sensitive gas (etc.) sensors, and other areas. The term "photonic-crystal fiber" was coined by Phillip Russell in 1995-1997 (he states (2003) that the idea dates to unpublished work in 1991), although other terms such as microstructured fiber and photonic-bandgap fiber are also used and the nomenclature in the field is not entirely consistent. More specific categories of PCF include holey fiber (and hole-assisted fiber) and Bragg fiber. ...more on Wikipedia about "Photonic-crystal fiber"
Plastic optical fiber (POF) is an optical fiber which is made out of plastic. traditionally PMMA (acrylic) is the core material, and fluorinated polymers are the cladding material. Since the late 1990's however, much higher-performance POF based on perfluorinated polymers (mainly polyperfluorobutenylvinylether) has begun to appear in the marketplace. ...more on Wikipedia about "Plastic optical fiber"
In fiber optics, a polarization-maintaining optical fiber (PM) is an optical fiber in which the polarization planes of lightwaves launched into the fiber are maintained during propagation with little or no cross-coupling of optical power between the polarization modes. There are several different designs with slightly different characteristics. Most work by inducing stress in the core via a non-circular cladding cross-section, or via rods of another material included within the cladding. ...more on Wikipedia about "Polarization-maintaining optical fiber"
In fiber optics, a quadruply clad fiber is a single-mode optical fiber that has four claddings. Each cladding has a refractive index lower than that of the core. With respect to one another, their relative refractive indices are, in order of distance from the core: lowest, highest, lower, higher. ...more on Wikipedia about "Quadruply clad fiber"
In telecommunication, a single-mode optical fiber is an optical fiber in which only the lowest order bound mode can propagate at the wavelength of interest. Single mode fibers are best at retaining the fidelity of each light pulse over longer distances and exhibit no dispersion caused by multiple spatial modes; thus more information can be transmitted per unit time giving single mode fibers a higher bandwidth in comparison with multi-mode fibers. A typical single mode optical fiber has a core radius of 5-10 micrometers and a cladding radius of 120 micrometers. Currently, data rates of up to 10 Gigabits/second are possible at distances of over 60 km with commercially available transceivers. ...more on Wikipedia about "Single-mode optical fiber"
In optical communications, zip-cord is a two-fiber cable consisting essentially of two single-fiber cables having their jackets conjoined by a strip of jacket material. The name is borrowed from electrical terminology referring to lamp cord. As with lamp cord, optical zip-cord may be easily furcated by slitting or tearing the two jackets apart, permitting the installation of optical connectors. Zip-cord cables include both loose- buffer and tight-buffer designs. ...more on Wikipedia about "Zip-cord"
