What is the difference between HDMI copper and fiber optic cables?

What is the difference between HDMI copper cable and fiber optic cable? 1, the core is not the same fiber optic HDMI cable using fiber optic core, the material is generally available in glass fiber and plastic fiber optic two. Comparison of the two materials, glass fiber loss is smaller, but the cost of plastic fiber is lower. In order to ensure performance is generally recommended for distances below 50 meters using plastic optical fiber, more than 50 meters using glass optical fiber. The ordinary HDMI cable is a copper core wire, of course, there are upgraded versions such as silver-plated copper and pure silver wire. Material is not the same decision fiber optic HDMI cable and regular HDMI cable in their respective areas of great difference. For example, fiber optic cable will be very thin, light, soft; and conventional copper core cable will be very thick, heavy, hard, etc. 2, the chip is not the same as the fiber optic HDMI cable using a photoelectric conversion chip engine, the need for two photoelectric conversion in order to achieve the transmission of signals: once the electrical signal into an optical signal, and then the optical signal in the fiber-optic line transmission, and then there is a light signal into electrical signals, signal transmission by the SOURCE side of the DISPLAY side of the effective transmission. DISPLAY end to realize the effective transmission of the signal from the SOURCE end to the DISPLAY end. Conventional HDMI cable is the use of electrical signal transmission, do not need to pass the two photoelectric conversion. 3, the transmission of different effectiveness of the above mentioned fiber optic HDMI cable and conventional HDMI cable using a different chip program principle, so in the transmission performance is also a difference. Generally speaking, due to the need for two photoelectric conversion, so within 10 meters of the short line of fiber optic HDMI cable and conventional HDMI cable in the transmission time difference is not large, so it is difficult to win or lose on the two short line performance. Fiber optic HDMI cable can support more than 150 meters of lossless signal transmission, and no signal amplifier. At the same time, due to the use of optical fiber as a transmission carrier, the signal high fidelity effect is better, and will not be affected by the electromagnetic radiation of the external environment, very suitable for games and high requirements of the industry needs. 4, the price difference is large At present, due to the fiber optic HDMI cable as a novelty, the industry scale and the user community is relatively small. So on the whole, fiber optic HDMI cable scale volume is small, so the price is still at a high level, generally more expensive than copper HDMI cable a few times or so. So the current conventional copper HDMI cable in the price-performance ratio is still irreplaceable.
