They work on the principle of total internal reflection. Optical fibers are thread like structure made of glass and plastic in which light travel by total internal reflection. Hence, based on the differences in the structure of the core, there are three main types of optical fibers. Pdf there has been intense research in the area of fiberoptic sensors over the last decade. This lesson will provide a definition of optical fiber, explore the different types and explain how the different types are used. Each type of fiber has different properties, with its own.
This application note discusses differences between various types of multimode and single mode optical fiber cable nomenclatures mentioned in isoiec and. Fiber types there are two main types of fiber optic cables. As mentioned in the article on the structure of optical fibers, the properties of data transmission via a fiber optic depend on the core. The second method involves the uses of fiber optic connectors. Single mode fiber smf multimode fiber mmf the difference is basically in the size of the core. The cable has total of 8 fibers which is a single mode fiber. The high signal bandwidth of optical fibers provides. A connector terminates the optical fiber inside a ceramic ferrule, using epoxy to hold the fiber in place.
This paper describes the main characteristics of optical fiber in general, and the properties of multimode and singlemode fiber mmf and smf in particular. Optical fibers are classified into two types based on the refractive index profile of core and cladding. In the specification based on a pair of limiting curves for each wavelength. An all inclusive list of the various optical fiber specification sheets. If more than one mode is transmitted through optical fiber, then it is said to be multimode fiber as shown in figure 2. Types of optical fibers physical structure of optical. Depending on the type of application and the reach to be achieved, various types of fiber may be considered and deployed. Indoor fiber optic cables are designed to either limit smoke vertically riser, or limit smoke and flame vertically and horizontally plenum.
The classification based on the refractive index is as follows. The types of optical fibers depend on the refractive index, materials used and mode of propagation of light. Everything you always wanted to know about optical. It consists of a core surrounded by the cladding which has a single uniform index of refraction. Other fiber typesspecifications can be offered upon request. Types of optical fiber learning outcome epg pathshala. The connectors can be mated and unmated at any time.
