With the development of technology, high-definition display devices are also constantly updated and iterated. Whether it is a monitor, LCD TV or a projector, they have all been upgraded from the original 1080P to 2K quality and 4K quality, and even 8K quality TVs can be found on the market /display.
Therefore, the associated transmission cables are also constantly innovating and breaking through, and the HDMI high-definition cable has also developed from the traditional copper core HDMI cable to the now popular optical fiber HDMI cable.
In response to the requirements of our customers, the DTECH 8K HDMI2.1 fiber optic cable has been developed and produced overtime, and it has been newly launched recently. Compared with the new copper-core HDMI cable and fiber-optic HDMI cable in the past, what is it better than? Let us take inventory for everyone one by one.
What is 8K HDMI2.1 fiber optic cable
First of all, let's explain a term: 8K HDMI2.1 fiber optic cable.
①8k
On TV it refers to the resolution. 8K is 16 times that of full HD TV and 4 times that of 4K TV; in terms of horizontal viewing angle, the best viewing level of 8K TV can reach 100°, but that of full HD TV and 4K TV is only 55°.
In terms of resolution, the resolution of 4K is 3840×2160 pixels, while the resolution of 8K reaches 7680×4320 pixels, which is 4 times that of 4K TV.
If you use an 8K TV to watch a Blu-ray blockbuster, the picture can only occupy 1/16 of the screen. In addition, the horizontal viewing angle of 4K TV is only 55°, while the horizontal viewing angle of 8K TV is 100°, which is absolutely exciting.
②HDMI2.1
HDMI2.1 is the latest standard of HDMI. Its advanced feature is that it adds many new functions and improves many performance parameters, making the display more beautiful and the system easier to operate.
The biggest change is that the bandwidth has soared to 48Gbps, which can fully support lossless video with resolutions and refresh rates such as 4K/120Hz, 8K/60Hz, and 10K; secondly, for videos, movies and games, a variety of enhanced refresh rate technologies have been added , to ensure smooth and stutter-free, including variable refresh rate, fast media switching, fast frame transfer, automatic low-latency mode, and more.
③HDMI fiber optic cable
It has different transmission characteristics from copper cable HDMI. The middle part of the cable body is an optical fiber transmission medium, which requires two photoelectric conversions to realize signal transmission.
The optical fiber HDMI cable adopts far more than the traditional copper wire technology, which can provide better brightness, contrast, color depth and color accuracy during long-distance transmission, effectively meet the requirements of cable EMI specifications, reduce interference to the external environment, and make the signal The transmission is more stable, so the signal loss rate is basically zero during the transmission process, which is a breakthrough in technology.
Where is the strength of DTECH 8K HDMI2.1 fiber optic cable
① Smaller size, lighter weight, softer thread body
Ordinary HDMI cables use copper cores, while optical fiber HDMI cables use optical fiber cores. The different materials of the cores determine that the optical fiber HDMI cables are thinner, softer, and much lighter in weight; and because of their super Strong anti-bending and anti-impact characteristics, it is better to choose optical fiber HDMI for large-area decoration embedding.
And due to the rapid development of technology, choosing the latest 8k HDMI2.1 optical fiber cable is the most cost-effective. After all, it will be used for many years after the cable is buried, which can avoid the trouble of changing the cable midway.
② Signal long-distance lossless transmission
The optical fiber HDMI cable comes with a photoelectric module chip, which uses optical signal transmission, and the long-distance signal attenuation is negligible. Without a standard chip, the signal loss is relatively high, and it is not suitable for long-distance transmission environments.
③No external electromagnetic interference
Ordinary HDMI cables transmit electrical signals through copper cores, which are susceptible to external electromagnetic interference, video frames are prone to drop, and audio signal-to-noise ratio is poor. The optical fiber HDMI cable transmits optical signals through optical fibers, free from external electromagnetic interference, and can achieve lossless transmission. It is very suitable for gamers and high-demand industry professionals.
④ With 48Gbps ultra-high-speed bandwidth
Ordinary HDMI cables are prone to signal attenuation, so it is difficult to meet the high-bandwidth transmission requirements of 48Gbps. The advantages of optical fiber HDMI cable are high transmission bandwidth, large communication capacity, strong insulation and anti-electromagnetic interference performance, which can let you experience the shocking feeling in 3D+4K games. For gamers, there is no need to worry about transmission bandwidth issues at all, and they can enjoy multi-level smooth and colorful game screens.
