Entering 2019, I found that 4K is already a bad street product, followed by the popularization of 8K and 10K. The bandwidth of HDMI has also been from the first version of 10.2G in version 1.4 to the 18G version in version 2.0, and now, HDMI2.1 The version of 48G, can be said to be leaps and bounds, today we talked together, HDMI 2.1 will drive the popularity of the optical fiber HDMI market.

 

 

 

 

The bandwidth of HDMI 2.1 has soared from 18Gbps to 48Gbps of HDMI 2.0b, which can fully support lossless video with ultra-high resolution and refresh rate such as 4K@120Hz, 8K@100/120Hz, 10K@100/120Hz, and support dynamic HDR. To this end, the HDMI 2.1 era requires a new ultra-high-speed data line to meet the throughput, but found an interesting question:

 

 

 

Cat 2. HDMI 2.0 data cable, passive cable can be used within 15 meters in length, and Cat.3 era HDMI 2.1 high-speed data cable, once more than 3 meters, you need to add power to drive signal transmission, more than 5 meters later Pure copper wire can not meet the demand, need to use AOC (active fiber cable).

 

 

 

 

Due to the high cost of optical fiber, photoelectric conversion module, and the like, the transmission is almost lossless and electromagnetic interference. At present, a 20-meter-long HDMI 2.0 active optical cable costs as much as four or five hundred yuan, and the input and output ports cannot be reversed.

4K TV has been popular for several years. Although the video resources have not kept up, but still can download a lot of 4K video, now 8K TV has gradually entered everyone's field of vision, but in addition to encountering similar content with 4K TV, 8K TV The popularity of this can be described as difficult, and one of the difficulties lies in the HDMI 2.1 cable.

 

 

 

 

Although HDMI 2.0 can transmit 8K video, it can only achieve 8K 30 frames. To achieve 8K 60 frames, it can only rely on HDMI 2.1. The standard of HDMI 2.1 has appeared, but the HDMI 2.1 cable has encountered difficulties. To achieve HDMI 2.1, more than 3 meters requires power supply to drive signal transmission. If it exceeds 5 meters, AOC active optical cable is needed, and copper wire cannot be satisfied. Click to view historical description: HDMI standard continues to be upgraded in 2018; now it is necessary to think of the association update specification. of.

 

 

 

This means that the cost of HDMI 2.1 cable will be very high, compared to the price of HDMI 2.0 with active optical cable is more than 400 yuan, the price of HDMI 2.1 with active optical cable is estimated to be higher, so the HDMI 2.1 cable problem will be It is something that needs to be solved before the popularization of 8K TV, but the price of this thing is not in front of the majority of cable manufacturers in China. Recently, there have been manufacturers aiming at the price war of HDMI fiber.

 

 

 

 

However, the optical HDMI industry is still temporarily opposed to the price war, but as the market demand increases, the manufacturers who want to increase market share are bound to increase, and the price war will be forced to the line.

 

 

 

In the 2019-2022 year, with the full support of the national policy, under the careful improvement of the seniors in the HDMI cable industry, driven by the development of technology, the HDMI fiber market will usher in the incremental turn of the market driven by the demand of the market! You can wait and see!
