HDMI: High Definition Multimedia interface High Definition Multimedia Interface (HDMI) is a fully digital video and sound transmission interface that can transmit uncompressed audio and video signals. Hdmi cables can be connected to set-top boxes, DVD players, personal computers, TV games, integrated expansion machines, digital audio and television sets..

HDMI D Type（Micro HDMI）：
19pin is mainly used in some small mobile devices, such as cameras, drones, robots, and a special end for the standard HDMI plug, one end for Micro HDMI(D type) industrial mobile phone.
HDMI C Type(mini-HDMI)：
The 19pin, scaled down version of the HDMIA type is mainly used in portable devices, such as DV, digital cameras, portable multimedia players, etc. SONY HDR-DR5E DV now uses this specification connector as the image output interface

02 AOC(active optical cable)
With the development of 5G technology, it uses the next generation of cellular technology, microwave transmission, fast coverage, 5G download speed up to 10Gbps, the future application is to use light technology as the mainstream, optical transmission technology, the development of consumer electronics to bring the best experience to consumers, as fiber instead of copper this step of progress is faster and more intensive, Fiber optic cable will definitely become the mainstream in two to three years. For example: If you only need a two or three meters long HDMI cable, then there is no need to choose optical fiber HDMI cable, traditional HDMI cable can, if you need a more than 10 meters HDMI cable, then optical fiber HDMI cable is your first choice, but this kind of long distance optical fiber HDMI cable need to pay attention to protection, do not fold large use, Decoration embedded should also be particularly careful, the bend needs a certain degree, not 90 degrees vertical folding, but because of the HDMI Association for cable research is relatively less, so the current market AOC series HDMI cable good and bad.
Working principle of optical fiber HDMI
It needs two processes to output to the display device terminal: electrical -> optical, optical -> electrical
Electricity -> light, light -> electricity; A light to electricity, electricity to light; The one on the right is a three-color lamp, and the one on the left is an illuminated white lamp; The one on the right with one more black device is the microprocessor, the brain of the whole wire, photoelectric conversion plus microprocessor control, the whole package is very small.
Let’s take a look at the internal structure of the fiber HDMI cable, a total of four layers, the innermost layer of 4 fiber core, it is worth mentioning is in stripping the fiber sheath, slightly with a bit of force to break the fiber core, but in the four-layer structure of the fiber HDMI cable can be very good protection of the fiber core, prevent fiber core pressure break, break, etc.; Four of them are very thin; The remaining tinned copper wire is the power and control signal for electricity, and the optical fiber is used to transmit data.
