Slim Run AV is an active optical cable system designed to connect two HDMI-enabled devices with high performance, low power consumption, and low cost. Using optical fiber to replace copper wire as the high-speed signal transmission medium, Slim Run can perfectly transmit 4Kat60HZ UHD video over distances up to 330 feet. Compared with traditional copper wire cables, Slim Run AV is not only longer, softer, and slimmer, but also offers better signal quality without the need for external power. Compared with other HDMI optical fiber transmission solutions, Slim Run AV is easier to use and is perfectly compatible, with no need for external adapters or converters.
