How to extend the transmission distance of HD?

HD, as the most mainstream audio and video interface at present, is enjoying a booming trend. However, the transmission distance of a typical HD cable is within 30 meters. In actual deployment, due to the layout of the site and the size of the equipment, the cable distance often exceeds 30 meters. So, how can the transmission distance of HD be extended? 1.HD extender: An HD extender is a device used to extend signals. It has one transmitting end and one receiving end. It is typically used in situations where long-distance direct connection cables cannot meet the transmission requirements. Generally, it is designed to ensure long-distance signal transmission without attenuation and is thus mostly active.
The transmitting end and the receiving end of the HD extender are connected through transmission media such as network cables, wireless, power, Bridges, coaxial, and optical fibers. At present, the most widely used type is the HD network cable extender, which uses Cat6/Cat6A network cables to connect and extend between the transmitting end and the receiving end, ensuring long-distance signal transmission without attenuation.
Common HD network cable extenders come in specifications of 60 meters, 120 meters, and 150 meters. Compared with HD cables, they are cheaper in cost and are an economical choice for long-distance transmission. Moreover, the fault-tolerance cost is low. If a single component in the entire transmission line is damaged, it can be updated and replaced for use. 2.HD optical fiber cable HD optical fiber cable can be regarded as the future of long-distance transmission. It uses optical fiber as the transmission medium, is not affected by external electromagnetic interference, and the signal transmission attenuation is almost zero. It can easily achieve ultra-long distance transmission of hundreds of meters.
The third-generation optical fiber composite HD high-definition cable pioneers a 150-meter ultra-long optical and electrical intelligence, setting a new benchmark! However, unlike copper wire HD, which can be connected freely at both ends, optical fiber HD cables have directionality. The transmitting end (source) and the receiving end (display) cannot be reversed. Special attention must be paid when wiring. 3. The short HD extension cable can be lengthened and is not subject to the "cable" system. HD male-to-female extension cables can be used to extend the transmission distance. Additionally, to address the inconvenience of plugging and unplugging home wall-mounted TVS and desktop computers with HD interfaces, the female HD port can be extended out, making it simpler and more convenient to use!
