What customers say
Professional installers highly value the Magenta MG-AOC-662 for its exceptional reliability in transmitting full 18Gbps HDMI 2.0 signals, especially over long distances where copper fails. This performance stability is crucial for mission-critical deployments. The plenum rating is a necessary compliance feature for air handling spaces. Installers also appreciate the cable’s manageable diameter and flexibility, which significantly eases routing through tight conduits, saving labor time. While the premium price point is noted, users accept it for the guaranteed performance and compliance. A key consideration is the need for careful handling during installation due to the delicate fiber optic components. Overall, this cable is recognized as a top-tier solution delivering consistent, high-quality results in demanding professional settings.
Know before you buy
No, the MG-AOC-662 is designed to be plug-and-play and draws all necessary power directly from the HDMI source, eliminating the need for bulky external power adapters.
Yes, it fully supports the HDMI 2.0 standard, allowing for 4K resolution at 60Hz with 4:4:4 chroma subsampling without any compression or signal degradation.
A Plenum (CMP) rating indicates that the cable jacket is constructed from fire-resistant materials that produce minimal smoke. This makes the cable safe and compliant for installation in air-handling spaces, such as drop ceilings or raised floors.
Because this is an active optical cable, it transmits data via fiber optics, which ensures zero latency and no signal loss, even at the maximum distance of 100 meters.
The hybrid design combines fiber for high-speed data transmission and copper for power, resulting in a relatively slim 4.5mm outer diameter. While it is durable, it remains flexible enough for standard routing in home theater or professional AV setups.
