Overview

KanexPro Active Fiber (AOC) HDMI 2.1 Cables deliver full, uncompressed 48Gbps HDMI 2.1 signal across runs of 30, 60, or 90 meters — far beyond the limits of passive copper HDMI cables. Built on an OM3 fiber + copper hybrid construction, these plug-and-play cables carry 8K@60Hz, 4K@120Hz, Dynamic HDR, and eARC with zero signal loss, drawing power directly from the HDMI source — no wall adapters, repeaters, or signal processors required.

Supporting eARC for AV receiver and soundbar integration, HDCP 2.2, full EDID management, and backward compatibility with HDMI 2.0 and 1.4, the CBL-AOCHDMI8K series is engineered for professional AV environments where EMI immunity, signal integrity, and installation simplicity are non-negotiable. Backed by KanexPro's 3-year warranty.
