User Manual
FAQ
What is the maximum resolution and refresh rate this cable supports?
This active optical cable supports 4K UHD resolution (3840 x 2160) at 60Hz refresh rate. It maintains this performance across the full 50-foot length, which exceeds the capabilities of standard copper HDMI cables at similar distances. The cable also supports HDR10 content for enhanced color depth and contrast in compatible displays and content sources.
Does this cable require external power to function?
Yes, the cable includes a 1.4-foot USB-A power cable that must be connected to a USB-A port or wall charger. This provides the necessary power for the active components that maintain signal integrity over the 50-foot length. The USB-C connector draws minimal power from the source device, but the active booster requires this additional power connection for optimal 4K performance.
Is this cable compatible with Thunderbolt 3 and Thunderbolt 4 devices?
Yes, the cable is fully compatible with Thunderbolt 3 and Thunderbolt 4 devices that support DisplayPort Alternate Mode over USB-C. It also works with standard USB-C ports supporting DP Alt Mode, USB4 implementations, and various laptops, tablets, and docking stations. The cable requires no special drivers or software and functions across Windows, macOS, and Linux operating systems.
What does CL3 rating mean for this cable?
CL3 (Class 3) is a fire safety rating indicating the cable jacket meets specific flame-retardant standards for in-wall installation in commercial buildings. This rating makes the cable suitable for permanent installations where cables run through walls, ceilings, or conduits in accordance with local electrical codes. The PVC jacket provides both durability and compliance with commercial installation requirements.
Can this cable transmit audio along with video?
Yes, the cable supports multi-channel audio transmission including 7.1 channel surround sound. It features Audio Return Channel (ARC) support for bidirectional audio between compatible devices and Consumer Electronics Control (CEC) for single-remote operation of connected equipment. The HDMI 2.0 specification ensures full audio compatibility with standard HDMI audio formats.
What is the difference between this active optical cable and a standard copper HDMI cable?
Active optical cables use fiber optic cores instead of copper wires to transmit signals, which eliminates electromagnetic interference and maintains signal integrity over much longer distances. While standard copper HDMI cables typically struggle with 4K signals beyond 15-25 feet, this AOC maintains full 4K 60Hz performance across 50 feet. The fiber construction also makes the cable lighter and more flexible than equivalent copper cables while providing better EMI protection in electrically noisy environments.
What resolution or display format is specified?
It features a display specification of 3840 x 2160, giving you clear visuals for work and media use.
What refresh rate or brightness details are available?
Display-oriented products are best judged through screen, connectivity, and installation specifications. Those facts help buyers confirm visual fit, mounting flexibility, and deployment suitability more clearly than generic summary text.
