Traditional copper-core HDMI cables have many problems in home theaters, commercial projections, and high-end audio-visual equipment fields. Their transmission distance is significantly limited, usually not exceeding 15 meters. At the same time, these cables are highly susceptible to electromagnetic interference, which can cause screen stuttering and color distortion. These issues have become the core concerns for users when setting up projection screens, starry sky ceilings, or wooden audio-visual cabinets systems.
Especially when the distance between devices exceeds 20 meters, signal attenuation can cause a series of serious problems. The picture will be delayed, the audio will be intermittent, and even lead to compatibility failures of the devices. Faced with these problems, users often have to compromise on picture quality or choose to add relay devices. However, adding relay devices not only increases costs but also makes the entire system more complex.
D-Bees Resox 4K optical fiber HDMI cable adopts optical fiber transmission technology. Through the photoelectric conversion module, it converts electrical signals into optical signals, achieving lossless transmission over a distance of up to 40 meters, effectively solving the distance anxiety problem of traditional cables. This cable supports 4K@60Hz, HDR, 4:4:4 color depth and 32-channel audio, and can perfectly match high-end projectors, Blu-ray players, game consoles and other devices. It ensures that projection screens present cinema-level picture quality, enables dynamic light and shadow on starry sky ceilings to be displayed without delay, and guarantees the stable operation of multiple devices in wooden audio-visual cabinets.
product features
This product features several remarkable characteristics. Firstly, it has the ability to transmit without loss of image quality over long distances. Its optical fiber structure is resistant to electromagnetic interference, with zero signal attenuation within 40 meters and a color reproduction rate as high as 99%, effectively solving the problem of image quality loss caused by long-distance transmission. Secondly, it has the advantage of plug-and-play compatibility. It supports the HDMI 2.0 standard and is compatible with devices such as PCs, game consoles, and Blu-ray players, without the need for additional drivers or settings. Thirdly, it has the feature of lightweight design and convenient wiring. The wire diameter is 60% smaller than that of copper core wires, allowing it to easily pass through the narrow wiring slots of wooden audio-visual cabinets, significantly reducing the difficulty of installation.
Tips
When using this product, there are some precautions to take. Avoid excessive bending as the optical fiber core is relatively fragile. During installation, keep the cable naturally curved with a radius of no less than 5 cm to prevent signal interruption. Both ends of the cable are marked with "Source" (signal source end) and "Display" (display end). When in use, strictly match the device interfaces. Reverse connection will result in no signal. Regularly clean the interfaces and wipe the HDMI connector with a lint-free cloth to prevent dust or oxidation from affecting the contact stability.
