MuxLab 500734 - 6G-SDI Extension Kit over OM4 Optical Fiber with Return Channel
The MuxLab 500734 is an advanced engineering solution designed specifically for professional broadcasting and high-end video production environments. This extender kit enables the transmission of ultra-high-definition SDI video signals (up to 4K at 30Hz using the 6G-SDI protocol) over distances that conventional copper cabling cannot reach, maintaining absolute signal integrity and zero latency.
Its most notable feature is its ability to handle a total bandwidth of 9 Gbps , enabling versatile, bidirectional configurations. Unlike simple unidirectional extenders, this equipment offers a true return channel . This means it can send the main camera (Master) signal to the control room while simultaneously receiving return signals (such as reference video, teleprompter, or program signals) and control data over the same fiber link.
Designed to work with OM4 multimode fiber optic cable, this system guarantees an operating range of up to 400 meters , ideal for live events, stadiums, or interconnecting studios. It also incorporates configurable SDI ports that automatically adapt, allowing for mixing different standards (for example, a 6G-SDI signal in one direction and a 3G-SDI signal in the opposite) to meet the specific needs of each shoot.
Main features
-
Long-range transmission: Supports distances of up to 400 meters using OM4 multimode optical fiber (and up to 300 meters with OM3).
-
6G-SDI and 4K support: Capable of handling resolutions up to 4K (3840x2160) at 30fps, also compatible with HD-SDI and 3G-SDI standards.
-
Flexible SDI ports: It has configurable BNC connectors that allow you to manage multiple combinations of input and output signals simultaneously (up to 5 physical BNC ports for mixed configurations).
-
Return Channel and Control: Facilitates sending return video for monitoring and features RS-232 signal pass-through, essential for camera control (CCU), Tally lights and remote management.
-
9 Gbps bandwidth: Allows simultaneous transmission of multiple data streams (e.g., a 6G signal + a 3G signal, or combinations of HD signals) without compression.
-
Robust design: Cast aluminum housing prepared for heavy-duty field use and mounting on camera rigs.
Benefits for the broadcast professional
This extender eliminates the complexity of running multiple long coaxial cables that suffer from attenuation. By centralizing video, return, and control signals onto a single fiber link, field deployment is dramatically simplified. Fiber optics' immunity to electromagnetic interference ensures a clean signal even in environments with significant electrical noise, such as stages with large lighting systems.
Use cases
-
Live event production: Connecting cameras on remote stages to the mobile unit (OB Van) with full control capability (CCU) and Tally.
-
Television studios: Links between different studios or control rooms located in opposite wings of a building.
-
Security and surveillance: Transmission of high-fidelity 4K camera signals to remote monitoring centers.
-
University and corporate campuses: Video signal distribution for auditoriums and conference rooms.
Frequently Asked Questions
Does the kit include the transmitter and receiver?
Yes, it's a complete point-to-point kit that includes both units to establish the link.
Can I use it to control the camera remotely?
Yes, thanks to its RS-232 pass-through port, you can connect camera controllers (RCP/OCP) to manage aperture, color, and other parameters from the control room.
What type of fiber optic connector does it use?
The equipment uses SFP modules with LC (Duplex) type connectors for fiber optic connection.
Is it compatible with cameras that are only HD or 3G?
Absolutely. The system automatically detects and adjusts to SD-SDI, HD-SDI, 3G-SDI, and 6G-SDI signals.
