With the development of technology, high-definition display equipment is also constantly updated and iterated, whether it is a display, LCD TV or projector, from the initial 1080P upgrade to 2k quality 4k quality, and even you can find 8k quality TV and display in the market.
Therefore, the associated transmission cables are also constantly innovating and making breakthroughs. HDMI high-definition cables have also developed from traditional copper-core HDMI cables to today’s popular optical fiber HDMI cables.
What is 8K HDMI2.1 optical fiber cable?
①【8K】
In terms of resolution, the resolution of 4K is 3840×2160 pixels, while the resolution of 8K reaches 7680×4320 pixels, which is four times that of 4K TV.
②【HDMI 2.1】
The biggest change of HDMI2.1 is that the bandwidth has soared to 48Gbps, which can fully support lossless videos with resolutions and refresh rates such as 4K/120Hz, 8K/60Hz, and 10K; secondly, a variety of enhanced features have been added for videos, movies, and games. Which can ensure smooth and stutter-free viewing, including variable refresh rate, fast media switching, fast frame transfer, automatic low-latency mode, and more.
③【HDMI optical fiber cable】
It has different transmission characteristics from copper cable HDMI. The middle wire body is an optical fiber transmission medium, which requires two photoelectric conversions to achieve signal transmission.
Optical fiber HDMI cables use technology that far exceeds that of traditional copper wires, and can provide better brightness, contrast, color depth and color accuracy during long-distance transmission. It effectively meets the requirements of cable EMI specifications and reduces interference to the external environment, making the signal transmission is more stable, so during the transmission process, the signal loss rate is basically zero. This is a technological breakthrough.
What are the advantages of DTECH 8K HDMI2.1 optical fiber cable?
1. Smaller size, lighter weight and softer wire 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 cable body is slimmer and softer, and the weight is correspondingly much lighter; and because of its ultra With strong bending resistance and impact resistance, it would be better to choose optical fiber HDMI for large-area decoration and buried wiring.
And due to the rapid development of technology, choosing the latest 8k HDMI2.1 fiber optic cable is the most cost-effective. After all, the cable will be used for many years after being buried, which can avoid the trouble of changing cables midway.
2. Lossless signal transmission over long distances
Optical fiber HDMI cables come with optoelectronic module chips and use optical signal transmission. Long-distance signal attenuation is negligible, truly achieving 100-meter long-distance low-loss transmission, ensuring the authenticity of images and high-fidelity audio; while copper-core HDMI cables generally There is no standard chip, the signal loss is relatively high, and it is not suitable for use in long-distance transmission environments.
3. Not subject to external electromagnetic interference
Ordinary HDMI cables transmit electrical signals through copper cores and are susceptible to external electromagnetic interference. Video frames are easily dropped and the audio signal-to-noise ratio is poor. Optical fiber HDMI cable transmits optical signals through optical fiber and is not subject to external electromagnetic interference. It can achieve lossless transmission and is very suitable for game e-sports players and people in high-demand industries.
4. Has 48Gbps ultra-high-speed bandwidth
Ordinary HDMI cables are difficult to meet the high-bandwidth transmission requirements of 48Gbps because the signal is easily attenuated. The advantages of optical fiber HDMI cables are high transmission bandwidth, large communication capacity, strong insulation and anti-electromagnetic interference properties, which can allow you to experience a shocking feeling in 3D+4K games. For gamers, there is no need to worry about transmission bandwidth issues and they can enjoy multi-layered, smooth and colorful game graphics.
In order to allow everyone to obtain clearer and more delicate picture quality, DTECH 8K HDMI2.1 optical fiber cable adopts 4-core optical fiber to transmit optical signals inside the cable body, which can effectively avoid mutual interference between high-frequency signals and make the transmission over 100 meters faster and more stable. Meets the need for long-distance decoration and buried wiring. And its total bandwidth reaches 48Gpbs, supports 8K/60Hz high-definition resolution, the clarity is 4 times that of 4K, and the details can be perfectly presented, making the vision more high-definition and real. In addition, DTECH 8K HDMI2.1 optical fiber cable supports dynamic HDR, providing more dynamic range and image details, making the bright areas of the picture brighter, the dark areas clear, and more depth and realism.
