Answer . All optical cables will sound almost exactly alike. There is no reason to spend a lot on these. Usually you get better shielding and performance by spending more, but optical signals are not interrupted by any source of outside interference. HDMI cables are similar, as it transmit a dig…ital signal, a very inexpensice HDMI cable will yield the same results as the most expensive. Buy all cables from monoprice.com, they are the industry standard equipment supplier for people in the know. ( Full Answer )

1: Fastest cable in sending and receiving data and information. 2: Small in size. 3: Water proof 4: Travel long distance (miles) 5: Last longer that other cables. by:kishon (Grenada)
Glass. There is a thin glass fiber, within another fiber of a different glass (so the two glass layers have a different index of refraction).
Optical fiber consist of a central core made of class or plastic which is surrounded by a cladding of material of refractive index slightly less than that of core and a protective jacket of insulating material. There are three types of optical fiber configuration.
Basically, the cable uses something called the critical angle to keep light inside it. This means the cable can be bent while still allowing light to travel through it. For more info go here: http://en.wikipedia.org/wiki/Fibre_optic NB please note that in some cases, the spelling FIBRE is used,… this is the same thing. Answer #2: To expand a bit on the first answer, light can travel down the optical fibre with low loss because each reflection on the wall of the fibre is "total internal reflection". The cable can be bent without significant loss but if you pinched the fibre, the change in shape would make the light hit the wall at the wrong angle and some would escape or be reflected. There is some loss in a fibre just as there is loss when light travels through a glass window. At the end of the cable, the signal can be converted back to an electrical signal with a sensor or it can enter optical circuitry. ( Full Answer )
The biggest advantage is that communication is very quick since data travels with the speed of light. www.whyisfiosbetter.viviti.com

Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. The light forms an electromagnetic carrier wave that is modulated to carry information. First developed in the 1970s, fiber-optic communication systems ha…ve revolutionized the telecommunications industry and have played a major role in the advent of the Information Age. Because of itsadvantages over electrical transmission, optical fibers have largely replaced copper wire communications in core networks in the developed world. The process of communicating using fiber-optics involves the following basic steps: Creating the optical signal involving the use of a transmitter, relaying the signal along the fiber, ensuring that the signal does not become too distorted or weak, receiving the optical signal, and converting it into an electrical signal. A Fiber Optic is a piece of plastic or glass with light going through it. A technology that uses glass or plastic to transmit data.this data can be a cable tv data,computer networking data or telephone data . ( Full Answer )
In the telcos, singlemode fiber is used to connect long distanceswitches, central offices and SLCs (subscriber loop carriers, smallswitches in pedestals in subdivisions or office parks or in thebasement of a larger building). Practically every telco's networkis now fiber optics except the connection… to the home. Fiber to thehome is not yet cost effective - especially since most homes do notwant (nor are willing to pay) for the high speed services thatwould justify fiber optics. ( Full Answer )

Optical fibres can carry more information as opposed to conventional cables. . Optical fibres are not affected by radio frequency interferrence . Information carried in an optical fibre can only be tapped physically (to steal information, the thief has to work on the optical fibre so that the ligh…t will travel to the thief) ( Full Answer )
The optical fibre is a thin fibre used to conduct light. It can also be used to transmit information as in telephone calls, Internet and cable television.
Fiber and fibre mean the same thing. The only difference is that fiber is derived from American English, and fibre is derived from European English.
The transmission characteristic of a fiber optic channel is highly non-linear. It makes it a very bad medium for analog signals. Luckily it doesn't interfere with digital transmissions.
It wasn't a one man effort, inventing fiber optics. Works were inspired by John Tyndall who first discovered light can travel an irregular path through glass. Alexander Graham Bell later contributed. Heinrich Lamm in 1930 put the first fiber optic cable together stranding cable together and sending …a signal across the wire. There were many other people who helped improve it over the year. Al Gore is not the father of Fiber Optic cables, in case you were wondering. ( Full Answer )
There are two main types of optical fibre used in telecommunications Multimode which is cheap and can only propagate light relatively short distances. This is now only commonly used within buildings. Single mode fibre has a graduated refractive index, this means it is manufactured with a varying den…sity from the outside of the fibre to the centre. This makes the light only bounce around in the middle of the already very thin fibre. The end result is far greater propogation distances, but it is more expensive to manufacture. This type of optical fibre is used between buildings, even in different cities. ( Full Answer )
fiber optics are applicated for Telecom and Datacom Storage Network CATV $ Multimedia Application Systems Integration for Long Haul, Metro and Access Network Fiber to the Indoor (FTTX) Test Local Area Network(LAN) More information can be sent through the same diameter of space as wired… communications systems. So that means that more (and faster) communications can be delivered. ( Full Answer )
Less expensive - Several miles of optical cable can be made cheaperthan equivalent lengths of copper wire. Higher carrying capacity - Because optical fibres are thinner thancopper wires, more fibres can be bundled into a given-diametercable than copper wires. This allows more phone lines to go over…the same cable or more channels to come through the cable into yourcable TV box. Less signal degradation - The loss of signal in optical fibre isless than in copper wire. Light signals - Unlike electrical signals in copper wires, lightsignals from one fibre do not interfere with those of other fibresin the same cable. This means clearer phone conversations or TVreception. Digital signals - Optical fibres are ideally suited for carryingdigital information, which is especially useful in computernetworks. Non-flammable - Because no electricity is passed through opticalfibres, there is no fire hazard. Lightweight and thin - An optical cable weighs less than acomparable copper wire cable. Optical fibres can be drawn tosmaller diameters than copper wire. Fibre-optic cables take up lessspace in the ground. ( Full Answer )
Optic Fibre has been installed extensively in Ireland since the early 1980's. A little known fact is one company has connected all Cities and Towns on its optic fibre backbone with 600 to 1000km of optic fibre cable being installed every year from the mid-80's up to 2000. Total cable length is in ex…cess of 20,000km and now this optic fibre backbone provides fully diverse dual node hubs and 100% protected SDH transmission. Additionally all major routes are equipped with wavelength multiplex (DWDM, providing from 16 to 160 wavelengths per fibre) Many other competitors also operate Networks with optic fibre backbone. much more info from email@example.com ( Full Answer )
Can be used mainly in transferring data e.g internet. These cables are used to provide fast intenet.
The delay earth-GEO satellite-back to earth is always about 250 ms. This is very high compared to delays in fibre optics. Nothing can change this fact as (currently) the speed of light is the upper limit for the signal propagation speed and the distance of the GEOs is almost the circumference of the… earth.

No, A fiber optic sensor is a sensor that uses optical fiber eitheras the sensing element ("intrinsic sensors"), or as a means ofrelaying signals from a remote sensor to the electronics thatprocess the signals ("extrinsic sensors").
Light travels through fiber optics the same way it travelseverywhere else, except when it scrapes against the inside of thecable it bounces off. Sort of like how a matchbox car goes down aplastic track. In fact, just like the toy car, the light willescape from the cable if it has to turn too quickly…. The name forthis maximum turn angle is called the "critical angle". This "critical angle" is different depending on what kind ofmaterial is in your cable (glass, plastic, metal, etc) as well aswhat the cable is sitting in (Air, water, space, etc). ( Full Answer )
Optic Fibre have lots of uses. The Internet uses fiber optic cables. It is a perfect application because it is digital information and the fiber optic cables send digitally. Telephones were one of the first uses for fiber optics. Many times internet and telephone signals travel over the same cable…s. Digital television (also known as cable TV) is often transmitted by fiber optic cables. ( Full Answer )
An optical modes refer to a specific solution of the Wave Equation which satiates the boundary conditions.
The decibel is used to express gain or loss relative to a known value. In fiber optics, the decibel is most commonly used to describe signal loss through the link after the light has left the transmitter.
optical fiber, is light transmission tools using of light in glass or plastic fibers on the principles of total reflection of light to achieve transmissionOptical fiber is a flexible see through fiber made of extrudedglass. This glass is slightly thicker than a human hair.
We know that fiber optics are tiny strands (approximately the width of a single strand of hair) of optical material that can be used to direct light either short or great distances away. These tiny optical strands use light to transmit data (at the speed of light c=3.00x10^(8) [m/s]=6.71x10^(8) [mph…]) to various sensors that detect the light and then record the information carried. Many fields use fiber optics in our world today, and these range from the medical fields to telecommunication purposes and to even signals from broadcasting cable companies. Our world is full of fiber optics! The uses in the medical field can range from using fiber optics as a light guide, which is called an endoscope (literally meaning "inside observation"), into the human body. The endoscope has two primary functions to view the inside of the human body. The inner portion of the fiber optic strands is used to collect visual data (by ways of coherent light) and then transmit it back to a screen visible in the doctor's office while the outer portion of the fiber optic strands is used to project light (by ways of incoherent light) inside the cavity to make viewing a lot easier. There are also fiber optics used in seismic and SONAR equipment which is carried in various vehicles. In seismic studies, a piece of equipment called the Ultra-High Sensitivity fiber-optic based sensor array is used to gather measurements of carbon capture and CCS monitoring (aka sequestration monitoring). CCS is a type of technology that allows for the capture of CO2 within our atmosphere (produced by power plants and other industrial outputs) and then transfers the CO2 deep into subsurface geological structures to help combat global warming. Then there is FOSS (Fiber-Optic Sonar System) which also uses fiber optics. Telecommunication, networking, and broadcasting techniques also require fiber optics to help transmit various amounts of data within seconds. Every time you get on the internet, you rely on fiber optics to bring the data to your screen. Every time you turn on the TV, you rely on fiber optics to bring up the broadcasting signals. Every time you pick up your landline (granted many people do not really have a landline anymore and just use cell phones), you use fiber optics to transmit your voice to your buddy on the other side. We use fiber optics all the time now, and really do not even notice how important they are in our life. Some high-tech cameras uses fiber optics to help direct light to a specific storage unit. Even modern day cars use fiber optics in the wiring of the engine to help indicate problems early on. Thousands of research equipment use fiber optics for data storage.

A fiber optic media is to connect widely by usin a thin wire which is known as fiber optical cable
Vast amounts of data can be transmitted long distances with fiber optical cable. Much more than regular coax
It is inserted into the uterus either transabdominally (through the abdomen) or transcervically (through the cervix) to visualize the fetus, to obtain fetal tissue samples, or to perform fetal surgery .
Splicing of optical fiber cable is done to extend a cable, making it longer, or to repair a break in it. Splicing is preferred over installation of connectors, because the connectors introduce losses and degrade reliability. Some connectors are necessary, but those are placed in a protected environm…ent, and their use is minimized. Besides, a typical cable, with 56 or more strands, would require 56 or more connectors, and that would create a large lump in the cable. ( Full Answer )
Fiber optic cables are used for carrying laser light pulses, which represent data of any kind.
Fiber optic cables are laid across the ocean by massive ships specially designed for the task. The are operate by crews 24/7.
ofc supports wide band width,where as others provide less s/r ratio is less ,more for remaining communications more immune to crosstalk for ofc,& less 4 remaining commn seure signal propagation in ofc
"Broadband" is just a relative description of how fast you can transmit data. (It implies a high rate) "Fiber optic" is a description of the physical method used to transmit the data: it's not by copper wire or by radio wave.
fiber optic cables are immune to electromagnetic interference. Anadded benefit of fiber optic cables is that they are not a firehazard. So the answer of this question would be "NO", they are not
Fiber Optic Cable is a thin glass cable in which data is transferred over via laser(s) that are shined through the glass media.
Fiber optics are used by the big organizations, these fiber opticsare pricey but are totally worth it for these organizations.
"A fiber optic cable consists of a core, wrapped in cladding, wrapped in buffer coating. Being composed of long, thin strands of pure glass, they function by transmitting light signals over long distances."
OCDMA: Its nothing but Optical code division multiple access or Orthogonal code divsion multiple access..
yes it is. when a light is incident on one end of fiber at a small angle it is refracted into the fiber.
Fiber optic cables are flexible because they are made out of plastic that refracts light and keeps it inside the cable. The light pretty much bounces its way down the inside of the cable by passing through different layers of plastic that bend the light and keeps it moving towards one direction.
The light will be considered energy and that energy bounces side to side through the fiber. There is a constant loss. So the smaller the fiber the less loss you would have.
