With the development of 5G technology, it uses the next-generation cellular technology, adopts microwave transmission, has fast speed and large coverage, and the 5G download speed is as high as 10Gbps. The future application is to use optical technology as the mainstream and optical transmission technology. Consumer electronic products bring the best experience to consumers. With the faster and more intensive progress of replacing copper with optical fiber, fiber optic cables will definitely become the mainstream of cables within two to three years. For example : If you only need an HDMI cable with a length of two or three meters, then there is no need to choose an optical HDMI cable, a traditional HDMI cable is fine. If you need an HDMI cable longer than 10 meters, then an optical HDMI cable is your first choice. It's just that this kind of long-distance fiber optic HDMI cable needs to be protected when using it. It should not be folded and used by a large amount. Special care should be taken when decorating and pre-embedding. A certain curvature is required at the corners, and no 90-degree vertical folding is required. However, due to the HDMI Association There are relatively few studies on optical cables, so the AOC series HDMI cables currently on the market are mixed.

Let's take a look at the internal structure of the optical fiber HDMI cable. There are four layers in total, and the innermost layer has four optical fiber cores. However, the optical fiber HDMI cable in the four-layer structure can well protect the optical fiber core and prevent the optical fiber core from being crushed, pulled, etc.; 4 of the optical fibers are very thin; the remaining tinned copper wires are power and electrical Optical fiber is used to transmit data.
