12G-SDI optical modules can transmit uncompressed 4K video over fiber, supporting high-bandwidth professional video applications.

Key Capabilities

Bandwidth and Resolution: These optical modules support 12G-SDI, which allows for 4K Ultra HD video at 60 Hz with 10-bit color depth, ensuring high-quality, uncompressed video transmission . Transmission Distance: Depending on the module and fiber type, 12G-SDI optical modules can transmit over single-mode fiber up to 20 km (Analog Way SFP-12G-OPT-TR) or up to 5 km for other extenders like the OPHIT FTSM . Blackmagic Design modules can extend signals up to 28 miles over fiber . Fiber Type and Connectors: Most modules use single-mode fiber with LC connectors, though some support multimode fiber. Fiber optics are preferred for long-distance transmission due to lower signal loss compared to coaxial cables . Compatibility: Many 12G-SDI optical modules are compatible with professional video equipment such as ATEM switchers, Studio Cameras, and SFP+ input/output cards. Some modules also support embedded audio channels and SDI test patterns for reliable integration . System Considerations: When deploying 12G-SDI, signal conditioning components like equalizers, reclockers, and cable drivers may be used for shorter coaxial runs, but fiber modules simplify long-distance setups and reduce the need for multiple cables .

Practical Applications

• Live broadcasting and studio production where uncompressed 4K video is required.
• Event production and AV installations needing long-distance video transmission without quality loss.
• Integration with video over IP systems for hybrid SDI/IP workflows, as some modules support both SDI and IP interfaces . In summary, 12G-SDI optical modules provide a reliable solution for transmitting 4K video over long distances, offering high bandwidth, compatibility with professional equipment, and flexible deployment options depending on fiber type and distance requirements .
