What is the difference in digital optical fiber cables for a home theater system?

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 ( Full Answer )

Advantages of optical fiber?

light travels through fiber optic cables(a hyper-thin glass tube) much faster than electricity, and the signal doesn't decay as much, making them more efficient.

What is the optical fiber?

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.

Analog transmission using fiber optic system?

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.

Who is the father fiber optics?

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 ( Full Answer )

Which type of optical fiber is the best?

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 ( Full Answer )

What has fiber optics done for society?

Anvantage of optic fiber?

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 ( Full Answer )

Is fiber optic in Ireland?

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 ( Full Answer )

When do you use fiber optics?

Can be used mainly in transferring data e.g internet. These cables are used to provide fast intenet.

Is fiber optics and Fiber optic sensors are same?

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").

How does light travel in fiber optics?

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 ( Full Answer )

How are optical fibers used in communication?

How does fiber optic cable work?

"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."

Why the optical fibers are flexible?

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.

Why is optical fiber is small?

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.
