Application Examples 

Live Events / Rental

Corporate / Enterprise

Long-distance video extension: Send uncompressed HDMI 1.4 signals over multimode fiber up to 2,500 m (1080p) or 1,100 m (4K30), ensuring reliable connectivity in large arenas or festivals. Signal integrity tools: Built-in test pattern generator and Pixel Accurate Reclocking help engineers verify links quickly during setup. Future-proof distribution: Deliver UHD/4K content (30 Hz RGB 4:4:4 or 60 Hz 4:2:0) with zero frame delay to LED walls, projectors, or IMAG systems. RS-232 integration: Control projectors or media players directly through the same optical link, simplifying cabling on tour.

Campus or enterprise fiber backbone: Extend HDMI, audio, and RS-232 across long building runs using LC or SC fiber connectors. Secure environments: No video compression and full HDCP compliance ensure compatibility with content-protected sources. Control room setups: Single-fiber technology carries HDMI, EDID/HDCP handshaking, and RS-232, reducing fiber counts and simplifying rack wiring. High-quality audio: Supports Dolby TrueHD and DTS-HD Master Audio alongside UHD video for enterprise AV deployments.
