The types of optical fibers depend on the refractive index, materials used and mode of propagation of light. Optical fibers are thread like structure made of glass and plastic in which light travel by total internal reflection. Types of optical fiber learning outcome epg pathshala. The advantages of this approach are that the connection is. Other fiber typesspecifications can be offered upon request.
Everything you always wanted to know about optical. Hence, based on the differences in the structure of the core, there are three main types of optical fibers. Optical fibers are classified into two types based on the refractive index profile of core and cladding. Differences between om1, om2, om3, om4, os1, os2 fibre optic. If more than one mode is transmitted through optical fiber, then it is said to be multimode fiber as shown in figure 2. The second method involves the uses of fiber optic connectors. The high signal bandwidth of optical fibers provides. Types of optical fibers physical structure of optical. Pdf there has been intense research in the area of fiberoptic sensors over the last decade.
Fiber types there are two main types of fiber optic cables. This application note discusses differences between various types of multimode and single mode optical fiber cable nomenclatures mentioned in isoiec and. The classification based on the refractive index is as follows. In the specification based on a pair of limiting curves for each wavelength. Single mode fiber smf multimode fiber mmf the difference is basically in the size of the core. An all inclusive list of the various optical fiber specification sheets. A connector terminates the optical fiber inside a ceramic ferrule, using epoxy to hold the fiber in place. Each type of fiber has different properties, with its own. Identify the basic components of a fiber optic communication system. This lesson will provide a definition of optical fiber, explore the different types and explain how the different types are used. It consists of a core surrounded by the cladding which has a single uniform index of refraction. As mentioned in the article on the structure of optical fibers, the properties of data transmission via a fiber optic depend on the core. Ptt 10 9 8 7 6 5 4 3 2 1 optical single mode fiber optimised at 1,310 andor 1,550nm.
