Fibre-optic Cable

What is Fibre-optic Cable?

Ans-

Fiber-optic cable or optical fibre consists of thin glass fibres that can carry information in the form of visible light.The typical optical fibre consists of a very narrow stand of glass or plastic called the Core.Around the core is a concentric layer of less dense glass or plastic called Cladding.The core diameter is in the range of 8-50 microns (1micron=10‐⁶ metres)While Cladding generally has a diameter of 125 microns.The cladding is covered by a protective coating of plastic,known as jacket.
Optical fibres transmit a beam of light by means of total internal reflection. When a light beam from a source enters the core,the core refracts the light and guides the light along its path.The cladding reflects the light pulses,Which can be carried over long distances via optical fibre cable at a very high speed,carry all the information.
Optical fiber has the capability to carry information at greater speeds ,higher bandwidth and data rate. A single optical fibre can pack hundreds of fibres,where each fiber has the capacity equivalent to that of thousands of twisted pair wires .The capacity broadens communication possibilities to include services such as video conferencing and interactive services. In addition fiber optic cables offer lower attenuation and superior performance and require fewer repeaters as compared to coaxial and twisted-pair cables. The major applications of the fiber optic cables are cable TV,military applications,long haul trunks,subscriber loops,LAN,rural and metropolitan trunks both.
