Paul Sanders Petrospec Engineering Knowing the technology and market, it is evident to me that AP Sensing is the forerunner in distributed optical sensing.
Fiber-optic communication Optical fiber is used as a medium for telecommunication and computer networking because it is flexible and Research paper fiber optic be bundled as cables. It is especially advantageous for long-distance communications, because light propagates through the fiber with much lower attenuation compared to electrical cables.
This allows long distances to be spanned with few repeaters. The net data rate data rate without overhead bytes per fiber is the per-channel data rate reduced by the FEC overhead, multiplied by the number of channels usually up to 80 in commercial dense WDM systems as of [update].
Fiber is also immune to electrical interference; there is no cross-talk between signals in different cables, and no pickup of environmental noise. Non-armored fiber cables do not conduct electricity, which makes fiber a good solution for protecting communications equipment in high voltage environments, such as power generation facilities, or metal communication structures prone to lightning strikes.
They can also be used in environments where explosive fumes are present, without danger of ignition. Wiretapping in this case, fiber tapping is more difficult compared to electrical connections, and there are concentric dual-core fibers that are said to be tap-proof.
For example, most high-definition televisions offer a digital audio optical connection. Advantages over copper wiring[ edit ] This section does not cite any sources. Please help improve this section by adding citations to reliable sources.
Unsourced material may be challenged and removed. May The advantages of optical fiber communication with respect to copper wire systems are: A single optical fiber can carry over 3, full-duplex voice calls or 90, TV channels. Immunity to electromagnetic interference: Light transmission through optical fibers is unaffected by other electromagnetic radiation nearby.
The optical fiber is electrically non-conductive, so it does not act as an antenna to pick up electromagnetic signals. Information traveling inside the optical fiber is immune to electromagnetic interferenceeven electromagnetic pulses generated by nuclear devices.
Low attenuation loss over long distances: Attenuation loss can be as low as 0. Optical fibers do not conduct electricity, preventing problems with ground loops and conduction of lightning.
Optical fibers can be strung on poles alongside high voltage power cables. Material cost and theft prevention: Conventional cable systems use large amounts of copper.
Global copper prices experienced a boom in the s, and copper has been a target of metal theft. Security of information passed down the cable: Copper can be tapped with very little chance of detection.
Fiber optic sensor Fibers have many uses in remote sensing. In some applications, the sensor is itself an optical fiber. In other cases, fiber is used to connect a non-fiberoptic sensor to a measurement system. Depending on the application, fiber may be used because of its small size, or the fact that no electrical power is needed at the remote location, or because many sensors can be multiplexed along the length of a fiber by using different wavelengths of light for each sensor, or by sensing the time delay as light passes along the fiber through each sensor.
Time delay can be determined using a device such as an optical time-domain reflectometer. Optical fibers can be used as sensors to measure straintemperaturepressureand other quantities by modifying a fiber so that the property to measure modulates the intensityphasepolarizationwavelengthor transit time of light in the fiber.
Sensors that vary the intensity of light are the simplest, since only a simple source and detector are required. A particularly useful feature of such fiber optic sensors is that they can, if required, provide distributed sensing over distances of up to one meter.
In contrast, highly localized measurements can be provided by integrating miniaturized sensing elements with the tip of the fiber.
Extrinsic fiber optic sensors use an optical fiber cablenormally a multi-mode one, to transmit modulated light from either a non-fiber optical sensor—or an electronic sensor connected to an optical transmitter.
A major benefit of extrinsic sensors is their ability to reach otherwise inaccessible places.Test your knowledge with amazing and interesting facts, trivia, quizzes, and brain teaser games on lausannecongress2018.com Intelligent fiber optic distributed temperature sensing systems and solutions for Fire Detection, Power Cable Monitoring, Oil and Gas up-/downstream, Geo and Hydrology, Industrial process monitoring.
