Different between fiber optical cable and copper cable?

Fiber optic cable is constructed out of glass or plastic, and uses light pulses to transmit data. Copper cable is made out of copper material (not glass or plastic) and uses electrical voltages to transmit signals.


What is an eide cable?

The cable connects between the motherboard of the computer and the hard-drive or optical drive.


Anvantage of optic fiber?

Less expensive - Several miles of optical cable can be made cheaper than equivalent lengths of copper wire. Higher carrying capacity - Because optical fibres are thinner than copper wires, more fibres 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 cable TV box. Less signal degradation - The loss of signal in optical fibre is less than in copper wire. Light signals - Unlike electrical signals in copper wires, light signals from one fibre do not interfere with those of other fibres in the same cable. This means clearer phone conversations or TV reception. Digital signals - Optical fibres are ideally suited for carrying digital information, which is especially useful in computer networks. Non-flammable - Because no electricity is passed through optical fibres, there is no fire hazard. Lightweight and thin - An optical cable weighs less than a comparable copper wire cable. Optical fibres can be drawn to smaller diameters than copper wire. Fibre-optic cables take up less space in the ground.


What is more common term for digital optical audio cable?

More common terms for digital optical audio cable; optical audio cable, cable, digital optical, but the shortest and most well-known term is "cable".


Does the gauge of fiber optical audio cable affect the audio quality?

No. As long as the signal is getting through, the gauge of the optical connection makes no difference.

What provides better sound quality- an optical cable to the TV then the system or directly to the system?

If you're connecting out of the device to the TV's optical in, then from the TV's optical out to the receiver, you're wasting an optical cable. Just connect directly to the receiver. There shouldn't be any sound quality difference either way since it's a digital connection, but it's much cleaner with only one cable.

Why optical fiber is slowly replacing copper cables in telecommunications?

Copper wire passes computer communications through the use of modulated carrier waves. RF energy is susceptible to resistance which reduces the signal over distance according to the Rho value of the copper wire. The longer the wire the higher the resistance the less signal is received at the other end. Secondly, being an RF signal, copper wire is susceptible to receiving signals from other sources which can cause interference though inter-modulation products caused by phase sum and difference between competing signals. Thirdly, RF signals are subject to standing waves which are caused by mismatches between feeders. This mismatch can prevent the signal from leaving the feeder (Copper wire) which in turn can prevent the signal from being received at the other end and cause the transmitter amplifier to become stressed and fail. Finally, copper wire is limited in the speed of the signal which can be transmitted. Fibre optical cable With multi-frequency fibre cables multiple signals can be sent down one cable at one time. Dependent on the purity for the fibre cable there is very little optical resistance runs of over 20km can be easily achieved. There is no transmission frequency limit to light. There is no standing wave problem. There is no interference problem from external sources. Fibre bundles carry more signals that the equivalent copper wire bundle in less physical space.


What kind of audio optical cable is best?

There is no difference in optical cable in terms of sound. If the signal is passing through, it is working. Having gold-plated end plugs or other cosmetic features is not necessary, since it is not an electrical connection. The only concern is getting the cable long enough so that it reaches the two devices without kinking. Sharp bends in optical cable can impede or block the transmission.
