MOSHOU Ultra-Slim 8K HDMI 2.1 Optical Fiber Cable – 3.5mm, 48Gbps, 8K60/4K120

The MOSHOU ultra-slim 8K HDMI 2.1 optical fiber cable combines a compact 3.5 mm cable diameter with OM4 optical transmission for clean routing across desktop, live-production, home-theater, conference and long-distance display installations. Its slim black cable and compact zinc-alloy connector housings fit more easily through restricted spaces than conventional thick HDMI cables.

Key Features

• Ultra-slim 3.5 mm cable: lightweight and flexible for routing behind displays, through cable channels and around compact equipment setups.
• Compact connector housing: approximately 56 × 16.9 × 8 mm, designed to require less clearance around HDMI ports.
• 48Gbps HDMI 2.1 transmission: supports high-bandwidth audio and video between compatible equipment.
• Up to 8K60 and 4K120: also supports compatible 2K high-refresh-rate signals for gaming, production and display applications.
• OM4 active optical construction: optical fibers carry high-speed signals over distance with reduced susceptibility to electromagnetic interference.
• Zinc-alloy connector shells: metal housings protect the active connector electronics while maintaining a compact profile.
• Dynamic picture support: passes compatible Dynamic HDR, HDR10 and Dolby Vision signals when supported by the complete system.
• Gaming and low-latency features: supports compatible VRR and ALLM operation from supported consoles, PCs and displays.
• Enhanced audio return: supports compatible eARC audio transmission between supported HDMI devices.
• Wide length selection: available from 0.5 m to 50 m for short equipment links and longer installed routes.

Directional Connection — Read Before Installation

This is a one-way active optical HDMI cable. Connect the end marked Source to the output device and the end marked Display to the receiving screen. The cable will not transmit normally when installed in reverse.

• Source: computer, graphics card, game console, camera with full-size HDMI output, Blu-ray player, set-top box or AV source.
• Display: television, monitor, projector, capture/receiving equipment or compatible display device.

Compatibility

Works with: HDMI-equipped TVs, monitors, projectors, desktop and laptop computers, graphics cards, game consoles, AV receivers, Blu-ray players and professional display equipment.

Live production use: suitable for compatible cameras, switchers, monitors and computers that use full-size HDMI connections. Check port type before ordering because many cameras use Mini HDMI or Micro HDMI.

Performance depends on the complete system: resolution, refresh rate, HDR, color depth, eARC, VRR and ALLM require compatible source equipment, receiving equipment, content and settings.

Not for: DisplayPort, USB-C, Mini HDMI or Micro HDMI ports without the correct active adapter. Do not reverse the Source and Display ends.
