How does an active HDMI cable work

Posted on 18 June 2021

The active HDMI cable contains signal amplifiers that ensure that both video and audio are transferred over long distances without signal loss. Pay attention to how you connect the cable. Because it only works in one direction you must connect the source end to the source and the target end to your display.

With a bandwidth of 10.2 and a core made of glass fibers that, due to new technology, eliminates the need for a power cable are there many advantages to an HDMI fiber optic cable. They provide superior performance in both speed and distance, they are lighter and thinner than their copper counterparts. In addition, they do not run the risk of causing power supply problems.

You can easily combine the active HDMI cable with a 2.1, so it can send 8K images at an acceleration of as much as 60 frames per second. This ensures that it is ideal for use with heavy programs and/or games. The cable also supports 3D technology and Deep Colour for optimal visualization.

PROCAB has quite an amount of active HDMI cables in their assortment. The CLD635A can deliver 4K (UltraHD) video, and audio, from your laptop, phone or tablet to your HD TV or any other 4K monitor. It is a true-plug-and-play solution, you simply connect the cable to your display and you are all set to go.

We also have the CLV310A available or you, which is an active optical HDMI 2.1 cable, designed for transmission of the next generation of 8K video content. Ready for future HDCP 2.3 content encryption, compatible with all current and emerging HDR standards (HLG, HDR-10 and HDR-10+, Dolby Vision, Perceptual Quantizer and SL-HDR-1) and compatible with eARC HD audio standard.

The CLV220A comes with a USB A to USB Micro B cable included, which is an accessory only required when the HDMI port on the transmitter side is delivering insufficient voltage (typically required when < 4.8 V) for powering the receiver end. The power is transferred from transmitter end to receiver end over the CLV220A cable. For more information about the USB, read our news item ‘the difference between USB types’.
