The Structure of HDMI Active optic fiber cable.
As the price of copper wire continues to rise and the mass production of photoelectric conversion modules, fiber optic cable is gradually replacing copper wire as the main force; today we will come together to understand the HDMI fiber optic cable, namely: HDMI-AOC (active optical cable, there source cable); it is an HDMI cable that uses optical fiber for the HDMI signal transmission line and integrates it into thephotoelectric conversion wire interface. Fiber is an abbreviation for optical fiber, a fiber made of glass or plastic. Can be used as a light transmission tool, the transmission principle is "perfect reflection of light"
Optical fiber HDMI, if it is to be sent to a display terminal, requires two processes: electricity ---> light ---> electricity.
TX and RX conversion reception: electric ---> light, light ---> electric; one electric light; one electric light; the right is a tricolor light, the left is an illuminated light; the right one is black. The device should be a microprocessor, the whole brain wire. Photoelectric conversion and microprocessor control, the whole package is particularly small.
Let's look at the internal structure of a fiber optic HDMI cable. There are four layers in total, and the inner layer is four layers of fiber. It is worth mentioning that when removing the fiber jacket.
little force is given to the core of the fiber. However, a four-layer fiber-optic HDMI cable can well protect the fiber core, prevent the fiber core from breaking, pulling, etc .; the four fibers are very thin; the remaining tinned copper wire is power and electricity. Control signal, fiber is used to send data! voice and video transmission actually realizes lossless transmission, video data and audio data are fully immune to external electromagnetic interference, which guarantees high accuracy of transmission signals; especially for audio information with very high transmission material requirements, very low noise level To ensure that the sound is very clear.
Lossless transmission application scenario
Light and light; because the material uses a very light fiber, the optical fiber HDMI cable is smaller and lighter than a traditional HDMI cable.
AOC HDMI application scenario
Long transmission distance; optical fiber transmission means that signal attenuation over long distances can be ignored, and the longest transmission distance can be more than 300 m. This feature is especially important in a home theater because the HDMI cable embedded in the living room theater is at least 10 meters.
Transmission distance comparison chart
High transmission bandwidth; fiber HDMI cable supports high bandwidth, 4K bandwidth, 3D video, no-pressure transmission.
Xiao Bian Comments: If you only need a two or three meter long HDMI cable, there is no need to choose a fiber optic HDMI cable, a traditional HDMI cable can be. If you need an HDMI cable that is more than 10 meters long, an HDMI cable is the first choice. Only this HDMI cable for the remote phone needs to be protected when used. Do not use it in large folds. Be careful when exposing the embedding. It needs a certain curvature at an angle, not a 90 degree vertical refraction.
