(1) The core is different
The optical fiber HDMI cable uses a fiber core, which is generally made of glass fiber. The ordinary HDMI cable uses a copper core wire, and of course an upgraded version such as silver-plated copper and sterling silver wire. The different materials determine the huge difference between the fiber HDMI cable and the conventional HDMI cable in their respective fields. For example, the fiber optic cable will be very thin, light, and soft; while the conventional copper core wire will be thick, heavy, and hard. More differences are explained below in detail.
(2) The chip is different
The optical fiber HDMI cable adopts the photoelectric conversion chip engine, which requires two photoelectric conversions to realize the signal transmission: once the electrical signal is converted into an optical signal, then the optical signal is transmitted in the optical fiber line, and then the optical signal is converted into an electrical signal to realize The signal is effectively transmitted from the SOURCE terminal to the DISPLAY terminal. The conventional HDMI cable uses electrical signal transmission and does not require two photoelectric conversions.
(3) Different transmission effectiveness
As mentioned above, the principle of the chip scheme adopted by the optical fiber HDMI cable and the conventional HDMI cable is different, and thus the transmission performance is also different. Generally speaking, since the photoelectric needs to be converted twice, the difference between the transmission time of the short-line optical HDMI cable and the conventional HDMI cable within 10 meters is not large, so it is difficult to have absolute victory and defeat in the performance of the short-term. Even on the basis of video and audio, the copper core HDMI cable will outperform the fiber optic HDMI cable in tone performance. However, in the long-distance transmission, the weakness of the ordinary copper core HDMI line is dwarfed. Accurately speaking, more than 10 meters away (some product work and poor material quality may support shorter) basically to achieve 4K@60HZ signal transmission is extremely difficult, it is easy to appear frame drop, flower screen phenomenon, even if it can barely transmit very Long but the signal is attenuated very seriously. At the distance of 20 meters and 30 meters, the performance of the copper core HDMI cable will be greatly reduced, and the signal amplifier is required to achieve the highest 1080P signal transmission. The advantages of fiber optic HDMI lines are shown on long distance transmissions. The fiber optic HDMI cable can support lossless transmission of 4K@60 4:4:4 signals over 150 meters without the need for a signal amplifier. At the same time, due to the use of optical fiber as the transmission carrier, the high fidelity effect of the signal is better and better, and it will not affect the electromagnetic radiation of the external environment, which is very suitable for games and high-demand industries.
Finally, it is necessary to talk about the user, in fact, the short-meter number does not need to use fiber optic HDMI cable, because the copper core HDMI cable can already meet your daily work and study entertainment needs, if it is used for engineering long meters, then you Need to carefully consider your own budget and choice, after all, the advantages of fiber optic HDMI cable in the long-term field is self-evident!
