< BR> in the digital display technology being used in consumer electronics and more and more consumers become the development trend of domestic displays the time, almost all users are aware
DV
I and HDMI is a pure digital signal interface, the transmission of digital signals can be demonstrated with the best picture quality images and effects. So, what kind of interface to be shown even more remarkable, this is a very interesting and worthy of careful consideration and measured.

<BR> Today's video settings become very complex, need to

Cable distance, at the same time, the connection from the connection to choose what technology to use decisive factor.
<BR> <BR> Cable when you want to buy when there are two options -
Copper
System
Cable
Or fiber-optic cable, which cable to use the debate on from the optical and coaxial digital audio cable into the concept began, and now, most people think their display is the same, no matter which one you use to refuse other one, will not affect audio quality. When using low-bandwidth audio, especially relatively short distance wiring case, copper cable or fiber optic cable is indeed the effect is the same.
<BR> <BR>, However, play full screen uncompressed digital signals are completely different situation, because the original high-resolution digital signal and the electrical properties of copper cable for connecting DVI or HDMI signal source, fiber-optic signal conversion technology is the most suitable choice. Of course, all of the video signal converters are used to set the same type of interface specifications. DVI and HDMI digital signals are high-speed high-bandwidth signal, the highest pixel signal 1080p signal that its image pixels 1920x1080, and updated 40 times per second. To high-definition signal so quickly update the speed and volume of a large number of bandwidth, copper cable resistance problems will cause signal loss - for example, the signal can not be updated, pixels hours or error, or no pictures, direct blue screen. When the copper cable from more than 15 feet, will have problems playing 1080p image; If it is 720p or 1080i broadcast signals in digital format, but also will keep the distance of copper cables at 25 feet. If more than this distance, better use of fiber optic cable.
<BR> <BR> Optical signal conversion technology is no resistance in theory, and therefore does not produce signal loss. The principle is that the video source signal into light, and the form of light to spread to the playback device, and then restore the digital video signal. If you want to see no loss of signal or pixel high-definition screen, you can also use the signal amplifier, of course, copper cable or fiber optic cables are used in conjunction with the signal amplifier has a different role. Amplifier installed in the copper cable is an electrical to make it more "robust" to reduce the wire length is too long for the signals generated losses; but the biggest problem with this technique is that the video signal is enhanced at the same time, the error The signal was enhanced, which causes the noise to be enhanced digital signal, and signal loss problems have not been fundamentally resolved. Another problem is that even with the signal
Amplifiers
, DVI and HDMI signals can not "re-strengthen" the case can only spread about 60 feet; This is not only inefficient, while the cost will be greatly improved. Optical signal conversion technology is actually the electronic signals into optical signals, therefore, can be over 495 feet to maintain signal integrity.
<BR> <BR> This is the IT organization and the cable companies now use fiber-optic network construction reasons, the current IT transmitted signal bandwidth (typically 0.6Gbps) than the uncompressed video signal (usually 1.65Gbps) is much lower, therefore, When the high-bandwidth digital signal coming era, fiber optic cables are becoming increasingly popular application is not surprising.
<BR> <BR> Copper cable and fiber optic cable in addition to technical principle of difference, when you select the signal to connect the solution, you may also want to consider the following aspects.
<BR> <BR> 1. Distance
<BR> <BR> If you are using a copper cable, it is best kept within 25 feet; If you need to use more than 25 feet length of the cable, the best choice for fiber optic cable.
<BR> <BR> 2. Forward-looking considerations
<BR> <BR> Need cables to connect the user with a long line of product life, generally achieve more than ten years. Taking into account the quality of cable and Ohira closely related to the display image quality and long-term connection with the display devices, so this
Investment
Is required. Popular screen resolution video playback system to 720p or 1080i, copper cables can apply. But the digital signal technology development at an alarming rate, you may in the near future to replace your

Players and TVs, then you need to consider whether your cable is well supported in the new video system (in particular, to cable buried in the wall of the user), it is best to buy a well supported 1080p signal transmission cable.
