Physics Fibre Optic Cable Diagram

Fiber optics is also the basis of the fiberscopes used in examining internal parts of the body.

Physics fibre optic cable diagram. In fiber optics the critical angle is described with respect to the parallel axis running down the middle of the fiber. In an optical fiber the light travels through the core m1 high index of refraction by constantly reflecting from the cladding m2 lower. It consists of a core surrounded by the cladding which has a single uniform index of refraction. Advantages over copper cable.

Fibre optic cables can carry signals with much less energy loss than copper cable as copper wires lose signal energy as heat p i 2 r due to their resistance. The types of optical fibers depend on the refractive index materials used and mode of propagation of light. Communication telephone transmission method uses fibre optic cables. Optical fibres transmit energy in the form of light pulses.

Types of optical fibers. The classification based on the refractive index is as follows. The refractive index of the optical fiber decreases as the. In telecommunications fiber optic technology is used to link computers within local area networks.

The uses of optical fibre are given bellow. In addition to giving an extremely wide bandwidth the fibre optic system has much thinner and light weight cables. The technology is similar to that of the coaxial cable except that the optical fibres can handle tens of thousands of conversations simultaneously. One cable can have as few as two strands or as many as several hundred.

A fiber optic cable is made up of incredibly thin strands of glass or plastic known as optical fibers. Fiber optics the science of transmitting data voice and images by the passage of light through thin transparent fibers. The overall cable construction is shown in the diagram below.
