Image Optical fibre.svg thumb right Light propagating in a multi mode fiber The core of a conventional optical fiber is a cylinder of glass or plastic that runs along the fiber s length. The core is surrounded by a medium with a lower index of refraction , typically a Cladding fiber optics cladding of a different glass, or plastic. Light travelling in the core reflects from the core cladding boundary due to total internal reflection , as long as the angle between the light and the boundary is less than the critical angle . As a result, the fiber transmits all ray optics ray s that enter the fiber with a sufficiently small angle to the fiber s axis. The limiting angle is called the Guided ray acceptance angle , and the rays that are confined by the core cladding boundary are called guided ray s. The core is characterized by its diameter or Cross section geometry cross sectional area. In most cases the core s cross section should be circular, but the diameter is more rigorously defined as the average of the diameters of the smallest circle that can be circumscribed about the core cladding boundary, and the largest circle that can be inscribed within the core cladding boundary. This allows for deviations from circularity due to manufacturing variation. Another commonly quoted statistic for core size is the mode field diameter . This is the diameter at which the intensity physics intensity of light in the fiber falls to some specified fraction of maximum usually 1 e sup 2 sup 13.5 . For single mode fiber, the mode field diameter is larger than the physical diameter of the core, because the light penetrates slightly into the cladding as an evanescent wave .

As designated by the National Fire Protection Association NFPA , this name is used for interior fiber optic cables which contain no Electrical conduction electrically conductive components, and which are certified for use in riser applications they are engineer ed to prevent the spread of fire from floor to floor in a building . Typically they are tested for compliance with ANSI UL 1666 1997, Standard Test for Flame Propagation Height of Electrical and Optical Fiber Cable Installed Vertically in Shafts . NFPA NEC 2005 Art 770.51 B FPN. They are distinct from optical fiber, nonconductive, plenum cable OFNP , and general purpose optical cable.

    Hard clad silica HCS or polymer clad fiber PCF is an optical fiber with a Core optical fiber core of silica glass diameter 200 m and an optical cladding made of special plastic diameter 230 m . In contrast to all silica fiber , the core and cladding can be separated from each other. Image HCS en 1.jpg thumb Configuration of HCS and fiber glass fiber optic cables Image HCS en 2.jpg thumb Spectral attenuation of fiber optics Due to their medium bandwidths and transmission rates of less than 100  MBit s, HCS fibers are suitable for distances of up to 2 km, e.g. in local networks in buildings and industry. Generally, the following applies The higher the attenuation, the shorter the distance. For comparison, plastic optical fiber s POF have low bandwidths and transmission rates less than 40 MBit s . They also have a high attenuation and therefore, the maximum distance is around 100 meters. Glass fibers on the other hand have very high bandwidths and transmission rates of up to GBit s.

  1. Optical Multi-Tree with Shuffle Exchange

    orphan date September 2010 Cleanup date November 2011 The interconnection network is the heart of a parallel processing system, and many systems have failed to meet their design goals for the design of their essential components. The Bandwidth signal processing bandwidth limitation of the electronic interconnects prompted the need for exploring alternatives that overcome this limitation. Optics is considered as an alternative that is capable of providing inherent communication , parallelism , high wikt connectivity connectivity and large bandwidth. When the communication distances exceed few millimeters, optical interconnects provide advantage over the electronic interconnects in term of Electric power power , speed and crosstalk property. Therefore, in the construction of very powerful and large multiprocessor systems, it is advantageous to interconnect close processors physically using electronic links and far processors kept in other package using optical links. Thus we use optical network like OMTSE , OTIS Disambiguation needed date November 2011 , and OMULT etc. The OMTSE network consists of two different systems called as optical and electrical.

  1. Graded-index fiber

    In fiber optics , a graded index or gradient index fiber is an optical fiber whose Fiber optics Principle of operation 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 . Because parts of the core closer to the fiber axis have a higher refractive index than the parts near the cladding, light rays follow sinusoidal paths down the fiber. The advantage of the graded index fiber compared to Multi mode optical fiber multimode step index fiber is the considerable decrease in modal dispersion . The most common refractive index profile for a graded index fiber is very nearly parabolic. The parabola parabolic profile results in continual refocusing of the rays in the core, and minimizes modal dispersion. This type of fiber is normalized by the International Telecommunications Union ITU T at recommendation G.651.1. ref Characteristics of a 50 125 m multimode graded index optical fibre cable for the optical access network, http www.itu.int itu t recommendations rec.aspx?id 9181 ref Pulse dispersion in a graded index optical fiber is given by math mathrm Pulse dispersion frac k delta n n 1 l c , , math where math delta n , math is the difference in refractive indices of core and cladding, math n 1 , math is the refractive index of the cladding, math l , math is the length of the fiber taken for observing the pulse dispersion, math c approx 3 times 10 8 mathrm m s , math is the speed of light , and math k , math is the constant of graded index profile.
