The use of fiber optic systems is expanding at a surprising Thursday. Only in the last 10 years, fibre communications systems have replaced almost all coaxial cables and twisted pair cables especially in the network backbone. This is particularly true for all communication links at a distance.
Why? This is simply. Fibre optic cable are easier to install, are lighter than traditional copper cables are much smaller than their electronic equivalents and, more importantly, they have much more bandwidth!
Given that fiber optic cables are lighter, they are easier to pull the son and cables careers. Other major advantages of fibre-optic cables, including their immunity against electromagnetic disturbances, longer distances repeater, low energy consumption and greater flexibility.
All professionals mentioned above make it very attractive fiber optics and above all very profitable.
The irresistible trend fiber optic applications for the transition from long distance (distance) to our table, our homes and our office. The terms are FTTC (Fiber to stem), FTTD (Fiber on the desktop), FTTH (Fiber on the homepage) and FTTB (Fiber on the building).
Fibre optic cable to allow our dreams of integrating all our telephone, Internet and television services. Fibre optic bandwidth, it is possible. It offers more capacity sufficient for all our voice, data and video requirements.
The transformation of copper fiberglass is greatly accelerated by the invention of optical fiber amplifier. Optical Fiber-optical amplifiers allowing the transmission of signals from very long distances without costly process of converting electronic signals, electronic and strengthening the conversion of optical signals back into the regenerative traditional doors.
Today, most transmission networks are always changing by electronic means such as switches and Cisco. But huge interest and efforts by the use of all optical equipment for the entire network switching accumulate in the industry. The main characteristic of all optical switching is in its almost unlimited transfer capacity.
It is still in prototype stage for controlling the light with the light, so that optical switches and circuits are still electronic circuits at the moment. The matrix of optical circuit switching, but always in control damage electronic circuits.
Optical Fiber is almost ideal medium for transmitting signals available today and in the foreseeable future. The excellent characteristics of the optical fibre is its immunity against electromagnetic disturbances. Optical circuits can be crossed in a common area without interference cross between them.
But there are problems, so the speed of the entire optical system development. The most obvious and important reason is compatible with the requirements inherited systems of fiber optics.
Another major advantage of fiber optics lies in the ability of multiplexing of his property on WDM (Wavelength Division Multiplexer). WDM each module multiple streams of data in another part of the light spectrum. Optical WDM is the equivalent of FDM (Frequency Division Multiplex). The use of WDM, the ability of a single channel fiber optic communication system by hundreds of times.
In addition to communication systems, optical fibre technologies are also widely used in medicine, lighting, scope, endoscopy, industry and more.
