Optical module HDMI

HDMI optical modules transmit high-resolution HDMI signals over fiber optic cables, enabling long-distance, interference-free video and audio transmission.

Overview

HDMI optical modules, also known as HDMI over fiber extenders or optical transceivers, convert electrical HDMI signals into optical signals for transmission over fiber optic cables. This allows HDMI 2.0 or higher signals, including 4K UHD at 60Hz with 4:4:4 chroma, to be transmitted over distances ranging from hundreds of meters to several kilometers without signal degradation, electrical interference, or latency issues .

Key Features

• High-Resolution Support: Most modules support 4K UHD (4096x2160 / 3840x2160) at 60Hz, HDR, and full chroma sampling (4:4:4), ensuring pristine video quality .
• Long-Distance Transmission: Depending on the model, HDMI optical modules can transmit signals up to 300 meters over multimode fiber or 10 km over single-mode fiber .
• HDMI Standards Compliance: Modules typically support HDCP 2.2/2.3, EDID, and CEC, ensuring compatibility with a wide range of HDMI devices .
• Additional Signal Support: Many modules also carry audio, USB 2.0, IR, RS-232, and Ethernet signals, enabling control and peripheral connectivity over the same fiber link .
• Electrical Isolation: Fiber optic transmission provides immunity to RFI and EMI, making these modules ideal for industrial, medical, or defense applications .
• Power Options: Some modules can be powered via USB or HDMI DDC 5V, with auto power-switching for reliability .

Typical Applications

• Professional AV Installations: Conference rooms, auditoriums, and control rooms where long-distance HDMI transmission is required.
• Broadcast and Defense: Secure, high-reliability video transmission for intelligence or military projects .
• Industrial and Medical Environments: Locations with high electromagnetic interference where electrical isolation is critical .
• Matrix Switches and Video Walls: Integration with modular AV systems for flexible routing and distribution .
