As the price of copper wire continues to rise and the mass production of photoelectric conversion modules, the fiber optic cable will gradually replace the copper wire to become the main force; today we come together to understand, HDMI fiber optic cable, namely: HDMI AOC (Active Optical Cable, there Source cable); it is an HDMI cable that uses optical fiber to make an HDMI signal transmission line and integrates its photoelectric conversion wire at the interface. The fiber is a shorthand for optical fiber, a fiber made of glass or plastic. Can be used as a light transmission tool, the transmission principle is 'total reflection of light'
Optical fiber HDMI, if it is to be output to the display device terminal, requires two processes: electricity--->light, light--->electric
TX and RX conversion reception: electricity ---> light, light ---> electricity; one light to electricity, one electric light; the right one is a three-color light, the left is an illuminated white light; the right one is a black The device should be the microprocessor, the whole wire of the brain. Photoelectric conversion plus microprocessor control, the entire package is particularly small.
Let's take a look at the internal structure of the fiber optic HDMI cable. There are four layers in total, and the innermost layer is four fiber cores. It is worth mentioning that when stripping the fiber jacket, the
fiber core is given a little force. Broken, however, the four-layer fiber optic HDMI cable can well protect the fiber core, prevent the fiber core from being broken, pulled, etc.; four of the fibers are very thin; the remaining tinned copper wire is power and electricity. The control signal, the fiber is used to transmit data!Lossless transmission; audio and video transmission truly realizes lossless transmission, video information and audio information are completely immune to external electromagnetic interference, ensuring high fidelity of transmission signals; especially for audio information with extremely high transmission material requirements, ultra-low noise floor To ensure that the sound is extremely pure.
Lossless transmission application scenario
Light weight and light weight; because the material uses a very light weight fiber, the optical fiber HDMI cable is smaller and lighter than the traditional HDMI cable.
AOC HDMI application scenario
Long transmission distance; using optical fiber transmission medium, signal transmission attenuation over long distances can be neglected, and the longest transmission distance can reach more than 300m. This feature is especially important for home theater, because even in the living room theater, the embedded HDMI cable is at least 10 meters.
Transmission distance comparison chart
High transmission bandwidth; fiber HDMI cable can support high bandwidth, for high-bandwidth 4K video, 3D video, transmission without pressure.
Xiao Bian Comments: If you only need a two or three meters long HDMI cable, then there is no need to choose a fiber optic HDMI cable, the traditional HDMI cable can be. If you need an HDMI cable that is more than 10 meters, then the fiber HDMI cable is your first choice. Only this long-distance optical fiber HDMI cable needs to be protected when it is used. Do not use it in large folds. Be careful when pre-embedding. It needs a certain degree of curvature at the corner, not 90 degrees vertical folding.
