Composite RCA is the most basic video signal. All the picture information is combined and sent over a single wire. The equipment at one end combines all the picture elements sends them over the wire, and then the receiving equipment separates them at the other end. Any changes to the video signal affect the whole and does not allow for adjustment of the individual elements. Also, clarity is often lost in the coding/decoding process.

Any changes to the video signal affect the whole and does not allow for adjustment of the individual elements. Also, clarity is often lost in the coding/decoding process.
S-Video is a step up from Composite RCA. S-Video takes the picture and separates it into two separate components; the Chrominance component (also called C), which is the color information and the Luminance (also called Y), which is the level of brightness, or rather the levels of black and white in the picture. This is why S-Video is sometimes called Y/C Video. The separation of the picture information allows the signals to be sent without coding/decoding, so there is no loss of clarity. Also, the separate signals are isolated from each other so change to one does not affect the other, which allows for a greater degree of control.
The next step up is Component Video. Component Video is the best way to connect your equipment. It takes the separation idea even further, by separating the picture into three component signals; two different color signals, and the “black-n-white” signal. The further separation of the color signal allows for better resolution and color saturation. Of the three, Component video is the only one with enough bandwidth to handle high-definition information, so it is mostly found on HDTV equipment and DVD players. Component video is often labeled Y/Pb/Pr.
Fiber cables are the cables containing thousands of fiber in a single cable. These cables are used as Monitor Cables, Network Cable, and Telephone Cables. The optical network of fiber cables easily accommodate in today’s demand for bandwidth on a point-to-point basis. However sometimes unused point-to-point potential bandwidth does not translate to operating profits, and it is estimated that no more than 1% of the optical fiber buried in recent years is actually 'lit'
