MuxLab IMU-500732-SM40 - 6G-SDI Fiber Optic Extension Kit (SM 40KM)
The MuxLab IMU-500732-SM40 is a high-performance professional video signal extension system designed to overcome the distance limitations of traditional coaxial cabling in broadcast and live production environments. This transceiver kit allows ultra-high-definition SDI signals, including 4K resolutions, to be sent over distances of up to 40 kilometers using a single-mode optical fiber.
What sets this model apart is its exceptional versatility in bandwidth management and connectivity. Thanks to its advanced architecture, the system supports multiple link configurations: it can transmit a native 6G-SDI signal over a single cable, two 3G-SDI signals, or up to four HD-SDI signals simultaneously to composite high-resolution images using Quad-Link . This flexibility makes it an indispensable tool for television studios, OB Vans, and long-distance camera deployments where signal integrity is critical.
The unit features automatic SDI link type detection, adjusting settings without complex manual intervention. In addition to embedded video and audio signals, the 500732-SM40 ensures the transmission of auxiliary data and control signals, including an RS-232 pass-through port for remote camera (PTZ or CCU) and tally control. Its robust aluminum housing design ensures durability in the field, while front-facing LED indicators provide immediate visual monitoring of the status of each SDI channel, synchronization, and power.

Benefits for the broadcast environment
For systems engineers and camera operators, the MuxLab 500732-SM40 eliminates the complexity of using multiple extenders for fragmented 4K signals. By consolidating up to four HD-SDI links or using the 6G-SDI standard over a single fiber, it dramatically reduces the weight and cost of cabling in remote productions. Its 40 km reach allows connecting sports stadiums to distant production centers without perceptible latency or image quality degradation, while maintaining the 4:2:2 color space intact.
Use cases
-
Live Events and Sports: Connecting 4K cameras located on the field of play directly with the mobile unit parked miles away.
-
Studio-to-Studio Connection: High-quality video link between corporate buildings or university campuses using existing dark fiber.
-
Long-Range Security and Surveillance: Transmission of high-definition security camera signals over large perimeters such as airports or borders.
-
Medical Imaging: Remote viewing of surgical procedures in auditoriums with diagnostic image quality without compression.
Frequently Asked Questions
-
Does the system compress the video signal?
No, the MuxLab 500732-SM40 performs a transparent and uncompressed transmission of the SDI signal, preserving the original bit-by-bit quality.
-
What type of fiber do I need for this model?
This specific model (SM40) requires Single Mode optical fiber with termination for the included SFP module (usually duplex LC connector).
-
Can I use it to send 4 independent HD camera signals?
The system is primarily designed to combine links (e.g., Quad-Link 4K). Although it technically carries the streams, it is recommended to verify the multiplexing configuration if you intend to use it as four completely independent and asynchronous channels, as its primary use is to extend a high-capacity source.
-
Does it support tally return?
Yes, control and tally signals can be sent to the camera through the RS-232 pass-through port.
Project description
Fiber optic extender for SDI signals capable of transmitting resolutions up to 4K (UHD) using 6G-SDI, Dual 3G-SDI, or Quad HD-SDI standards. The system consists of a transmitter and receiver equipped with SFP+ modules for single-mode fiber, achieving distances of up to 40 kilometers. It features four BNC input and four BNC output interfaces to support multi-link configurations (SMPTE 425M, 424M, 292M, 259M). It includes a dedicated sync port, an RS-232 interface for control, and a USB service port. Power is supplied via locking connectors, and the metal chassis is designed for professional mounting.
