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 digital 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.
Fiber optics are cables that are used to transmit data at the speed of light. This uis especially popular with Verizon FiOS services. for details on fios go to www.whyisfiosbe…tter.viviti.com
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 protec…tive jacket of insulating material. There are three types of optical fiber configuration.

Also are three types of optical fiber configuration : 1) single mode step index fiber 2) multi mode step index fiber 3) multi mode graded index fiber
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 electromag…netic carrier wave that is modulated to carry information. First developed in the 1970s, fiber-optic communication systems have 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 .

Optical fibres can carry more information as opposed to conventional cables. . Optical fibres are not affected by radio frequency interferrence . Information carried in an o…ptical fibre can only be tapped physically (to steal information, the thief has to work on the optical fibre so that the light will travel to the thief)
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 optic is faster but delicate. needs to be handled carefullyduring installation and maintenance
Yes, they are the exact same thing
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 tran…smissions.
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.
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 li…ght has left the transmitter.

there are 1 and 5 main fiber optic system
Most closed circuit TV uses coaxial cable, not fiber although larger systems are increasingly using fiber components. Currently, quality is limited by the availability of ca…meras, switchers and recorders in the security and monitoring market so the use of fiber has limited benefits. However, there are installations that use it to prepare for the higher data rates of future HD systems, to support longer signal routes than copper supports easily and to make use of fiber based infra-structure that is already in place. Although the future upgrade path can justify the extra expense, in some cases, it is simply an expensive method of achieving the same result as a copper installation.
