A big difference from the past is that we live in a world which vary from minute to minute. Nothing in the world gives us more power and confidence than having information. Because of the flow of information, we can communicate with each other to achieve the successful advancement of humankind. Transmission of information is imperative to the expansion of our horizons.
All these changes are due to the existence of optical fiber. The article mainly cover the basis of fiber optics in terms of its origin, transmission, uses and applications.
A technology that uses glass (or plastic) threads (fibers) to transmit data. A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves.History of optical fiber began with the invention of “optical telegraph” by French Chappe brothers .Optical telegraph is the system comprised of series of light mounted on towers where operators would relay a message from one tower to another.
Then in 1840, Physicists Daniel collodon and Jacques Babinet showed that light could be directed along jet of water for fountain.
The capacity and speed of such a system is one of the greatest benefits to using fiber optic systems. Because the speed is really matters for the delivery and reception of information. Light travels faster than an electrical system. Fiber optic cables also have a much higher capacity for bandwidth than the more traditional copper cables.
Optical systems are more secure than traditional mediums. Information is easy to be leaked because of the electromagnetic interference. Optical fiber makes it impossible to remotely detect the signal being transmitted within the cable. Accessing the fiber requires intervention that is easily detectable by security surveillance. These sutiations make fiber extremely attractive to governments, and companies requiring increased security of data.
Fiber optic cables are tubes of glass that find a host of uses in a variety of fields.
Fiber optical cables have made excellent mediums for telecommunication networks due to their flexibility and durability. Fiber is laid and used for transmitting and receiving purposes. Fiber optic cables can carry a large number of different signals simultaneously through a technique called wavelength division multiplexing. This increases their efficiency and makes them ideal for transporting large quantities of independent signals. At the same time, Fiber Optic Adaptor can dock of the same or different optical fiber connectors in optical fiber line which make the optical path goes smoothly wih little loss.
In medicine, optical fibers enable physicians to look and work inside the body through tiny incisions without having to perform surgery.
Fiber optic cables are found in hospitals and doctor's offices around the world. They form the backbone of advanced imaging techniques used in digital diagnostics since they can efficiently transport large quantities of sensitive data. Because fiber optical cables are inert, they introduce no risk of infection. Their flexibility make fiber optic cables the natural choice for endoscopes used in minimally invasive surgical procedures.
