This 4K HDMI® cable provides a 100ft (30m) connection between your HDMI devices, with no signal loss. The cable supports HDMI 2.0 devices, and it’s backward compatible with all of your older HDMI devices. The active HDMI cable’s built-in amplifier circuitry boosts the HDMI signal with no external power required. The booster circuit, combined with the optical cable, supports longer connections than a typical HDMI cable. The cable features a mixture of both fiber and copper wire, which provides a thinner core than regular copper HDMI cables and makes it perfect for installation in narrow spaces. The fiber composition also makes the cable immune to EMI (electromagnetic interference) and RFI (radio frequency interference).
