fiber optic communications
Fiber Optics is a significant technology used in many different areas of communications. With the explosion of the internet, fiber optics can readily provide the capacity of data that is transmitted with its gigabit speeds. As more breakthroughs in technology occur, it will spread to every aspect of the industry. Telephones, Fax Machines, Radios, Television Broadcasting, and even satellites use this highly reliable light wave technology. The telecommunications industry receives the most benefits from fiber optics. It allows for the transmission of audio, video, and data information in high quality. Fiber optics uses light pulses directed down a tiny glass fiber in order to relay information. Two different types of fibers are in use today, single mode, and multimode. Each of these types of fibers are made of three different parts, the core, the cladding, and the buffer. While singlemode and multimode fibers are composed of the same components, they do still differ. Singlemode fibers are significantly smaller than multimode fibers. The core of the fiber is the most crucial part of any fiber. In the core is where the light signals themselves travel through. Because of how easily light r
For example, a single glass fiber can replace 10,000 telephone wires, and will replace even more wires as a signal compression technologies improve. With the invention of a "tow-tone" laser, each of these wavelengths can be emitted from the same laser simultaneously. Using copper and electricity to transmit information can work at a maximum of 1 gigahertz. Also, a single fiber cable with a diameter of 1 centimeter can carry more that a million conversations at a time. Lasers can send information very efficiently. The average human hair has a diameter of approximately 100 microns, making the core of a singlemode fiber about 1/13 the size of a human hair. Light wave communication was a technology that the world was awaiting for a new universe of technology. Using light waves, fiber optics makes interference as close to impossible as possible. Multimode fibers are somewhat different from singlemode. Multimode fibers have a much larger core than singlemode. Outside of the cladding is the protective covering called the buffering. The core is larger because the light waves are emitted by a LED, light emitting diode which emits waves of 890 nanometers. For this, there is a layer of glass outside of the core called the cladding layer. Performance with fiber optics is incredibly higher with still lower costs.
