Use metal armor photoelectric composite cable with four-light and seven-copper structure, anti-interference and tensile strength; 6. The appearance of the product is made of zinc alloy, which is resistant to compression and wear, and the port is gold-plated to ensure stable signal transmission; 7. Widely applicable to large-screen broadcasting, e-sports games, home audio-visual, multimedia video playback and other display places. Ⅱ. Product Description 1. This product is an armored fiber optic HDMI 2.1 cable, which has a thicker steel cable layer than the ordinary fiber optic HDMI 2.1 cable, which can greatly prevent the fiber optic HDMI cable from being trampled, heavily pressed, and bent to cause damage to the cable. 2. It has better flexibility and bendability, even if it is folded in half, there is no need to worry about the fiber core breakage and damage in the armored optical fiber HDMI cable 2.1, which is more convenient and quicker for the tube to drag the cable. Since the thick steel armor metal layer is fully wrapped, compared with the addition of a thick shielding layer, it can better isolate and protect electromagnetic interference and electromagnetic radiation. 3. Especially for some medical systems,security monitoring systems and other places that require strict electromagnetic isolation, the armored optical fiber HDMI cable version 2.1 has a better application effect. Suitable for digital home theaters, classrooms, security cameras, meeting rooms,auditoriums, LED billboar ds, outdoor advertising, airport and stadium panel information display, etc.
