Fiber Optics #02 Need for Optical Communication & Advantages of fiber optic communication system.
Welcome to the 2nd lecture of fiber optics. In this lecture we will see what is the need for optical telecommunication. We will outline the advantages of a fiber optic communication system. Fiber Optic Communication is the most modern and advanced mode of data communication which has very recent roots dating back to not more than 40 years ago. Communication Scientists all over the world were in an incessant search of a wideband and low-loss medium of data communication which could be used at high
data rates with the least amount of lost possible. This constant search, for such a medium, led to development of optical fiber communication.
Why are fiber-optic systems revolutionizing telecommunications? Compared to conventional metal wire (copper wire), optical fibers provide:
Digital signals: Optical fibers are ideally suited for carrying digital information, which is especially useful in computer networks.
Higher carrying capacity: Because optical fibers are thinner than copper wires, more fibers can be bundled into a given-diameter cable than copper wires. This allows more phone lines to go over the same cable or more channels to come through the cable into your business or home.
Less signal degradation: The loss of signal in optical fiber is less than in copper wire.
Less expensive: Several miles of optical cable can be made cheaper than equivalent lengths of copper wire. This saves your provider and you money.
Thinner: Optical fibers can be drawn to smaller diameters than copper wire.
Light signals: Unlike electrical signals in copper wires, light signals from one fiber do not interfere with those of other fibers in the same cable. This means clearer phone conversations or TV reception.
Low power: Because signals in optical fibers degrade less, lower-power transmitters can be used instead of the high-voltage electrical transmitters needed for copper wires. Again, this saves your provider and you money.
Non-flammable: Because no electricity is passed through optical fibers, there is no fire hazard.
Lightweight: An optical cable weighs less than a comparable copper wire cable. Fiber-optic cables take up less space in the ground.
Flexible: Because fiber optics are so flexible and can transmit and receive light, they are used in many
flexible digital cameras for medical imaging in bronchoscopes, endoscopes, laparoscopes; for mechanical imaging used in inspecting mechanical welds in pipes and engines (in airplanes, rockets, space shuttles, cars); and in Plumbing, to inspect sewer lines
