HDMI 2.1 will drive the popularization of the optical fiber HDMI market

Entering into 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 changed from 10.2G in version 1.4 to 18G in version 2.0, and now, HDMI2.1 The 48G version can be said to be advancing by leaps and bounds. Let’s talk about it today. HDMI 2.1 will drive the popularization of the optical fiber HDMI market.

 

 

The bandwidth of HDMI 2.1 has soared from 18Gbps of HDMI 2.0b to 48Gbps, which can fully support 4K@120Hz, 8K@100/120Hz, 10K@100/120Hz and other ultra-high resolution and lossless video with refresh rate, and support dynamic HDR at the same time For this reason, in the HDMI2.1 era, a brand-new ultra-high-speed data line is needed to meet the throughput, but I found a very interesting problem:

 

The HDMI 2.0 data cable in the Cat 2. era can use passive cables within 15 meters in length, while the HDMI 2.1 high-speed data cable in the Cat.3 era requires power supply to drive signal transmission once it exceeds 3 meters. Pure copper wire cannot meet the demand, and AOC (active optical cable) is required.

Due to the high cost of optical fiber, photoelectric conversion module, etc., while the transmission is almost lossless and no electromagnetic interference, the current price of a 20-meter HDMI 2.0 active optical cable is as high as four to five hundred yuan, and the input and output ports cannot be reversed.

 

 

4K TV has been popular for several years. Although video resources have not kept up, many 4K videos can still be downloaded. Now 8K TV has gradually entered everyone’s field of vision. However, it is really embarrassing to encounter content similar to 4K TV. It can be described as difficult to popularize, one of which lies in the HDMI 2.1 cable.

 

Although HDMI 2.0 can transmit 8K video, it can only achieve 8K 30 frames. If you want to achieve 8K 60 frames, you can only rely on HDMI 2.1. The HDMI 2.1 standard has already appeared, but the HDMI 2.1 cable has encountered difficulties. To achieve HDMI 2.1, power supply is required to drive signal transmission if it exceeds 3 meters, and AOC active optical cable is required for more than 5 meters, which cannot be met by copper wire. Click to view the historical description: The HDMI standard continues to be upgraded in 2018; now it is inevitable to think of the association's updated specifications of.

 

This means that the cost of HDMI 2.1 cables will be very high. Compared with HDMI 2.0 that uses active optical cables, the price of HDMI 2.0 is more than 400 yuan. The price of HDMI 2.1 that uses active optical cables is estimated to be even higher. Therefore, HDMI 2.1 cable problems will This is something that needs to be solved before 8K TV becomes popular, but the price is nothing in front of the majority of cable manufacturers in China. Recently, some manufacturers have aimed at the price war of HDMI optical fiber.

 

 

However, the optical fiber HDMI industry still opposes the price war for the time being, but with the increase in market demand, the number of manufacturers who want to increase market share is bound to increase, and the price war will be forced to go online.

 

 

In 2019-2022, with the strong support of national policies, the careful improvement of the predecessors of the HDMI cable industry, and the strong drive of technological development, the HDMI optical fiber market will usher in an incremental turn driven by market demand! You can wait and see!
