what is meant by optical fibre?
Answers
An optical fiber is a flexible, transparent strand of very pure glass that acts as a light pipe to transmit light between two ends of the fiber. Optical fibers have a core surrounded by a cladding layer made of dielectric material. The optical signals in the core are confined by establishing a refractive index that is greater than the cladding
a long thin thread of glass or plastic along which information can be sent through a phone or computer system, using light

• Next came an all-optical experiment using an optical fibre as nonlinear medium { 32 }, demonstrating 12 and chaos.
• An optical fibre uses total internal reflection to carry a light beam over long distance and around corners.
• IskraTEL specialists are currently laying optical fibre cables to connect the city's exchanges.
• The characteristics of optical fibre change with temperature, sufficiently to change the required magnetic field period.
• You will also need a length of optical fibre.
• It also explains why it is virtually certain that Britain's main trunk lines will rely on optical fibre.
• It is interesting to examine the optical fibre before using it in the communications system.
• The obstacle to optical fibre communication is lift loss due to impurities in the glass.
