Applications of optical fibres

Due to much lower attenuation and interference, optical fiber has large advantages over existing copper wire in long-distance and high-demand applications. However, infrastructure development within cities was relatively difficult and time-consuming, and fiber-optic systems were complex and . Optical communication is an important part of non-intrusive surgical methods, popularly known as endoscopy. In such applications , a minute, bright light is used to light up the surgery area within the body, making it possible to reduce the number and . A technology that uses glass (or plastic) threads (fibers) to transmit data.

History of optical fiber began with the invention of “optical telegraph” by .

This research paper will cover the basis of fiber optics in terms of its transmission, communication, origin, uses and applications.

The use and demand for optical fiber has grown tremendously and optical - fiber applications are numerous. Telecommunication applications are widesprea ranging from global networks to desktop computers. Fiber optics transports light in.


These involve the transmission of voice, data, or video over distances . The intrinsic physical characteristics of optical fiber combined with its versatility in remote sensing make it an attractive technology for biomedical applications. Universalppts modern physics,concepts of modern physics,modern physics books,rev modern physics,modern physics lecture notes, mod. However, for some special applications one requires specialty fibers made from other types of glasses, e. This tutorial will describe the needs for bio-medical sensing and illustrate—through several real-life application examples—the benefits brought by optical fibers and fiberoptic sensors and their ongoing development.


Key technical challenges and industry trends will be identified. The most significant and prevalent applications of fiber optics in medicine are in the imaging and illumination components of endoscopes. Flexible and rigid multifibers composed of step-index fibers and graded-index imaging rods are extensively used for visualization of internal organs and tissue which are accessible . It also increasingly enables biomedical sensors that aid in minimally invasive medical procedures. These advantages have led to fiber becoming the transport medium of choice for . Because optical fiber is not subject to electromagnetic interference, it is ideal for various tests like MRI scans. Other medical applications for fiber optics include X-ray imaging, endoscopy, light therapy and surgical microscopy.


But just as electricity can power many types of machines, beams of light can carry many types of information—so they can help us in . Within the oil and gas industry, there are two main areas of use for optical fibers , firstly for sensing and secondly for communication. An optical fiber cable, also known as fiber optic cable, is an assembly similar to an electrical cable, but containing one or more optical fibers that are used to carry light. Depending on the application , fiber may be used because . These fibres are rich in optoelectronic functionality and offer extended transmission bands across the infrared spectral region so that their application potential is vast. Among others, their properties regarding bandwidth, attenuation, and influence of external parameters are discussed.
