MuxLab - 500734 SM40 Extendeur 6G-SDI sur fibre avec canal retour SM 40 km

Forty kilometres is the distance that often separates two studios in the same region, or a remote event site from the production centre. On this scale, the MuxLab 500734 extender with return channel doesn't just carry a signal; it weaves a digital umbilical cable between the camera and the control room. It ensures that every element of a professional production - the main 4K image, the return stream for the cameraman, talk-back communications and control data - travels synchronously and infallibly over the same single-mode fibre.

The engineering behind this performance is both intelligent and accessible. Automatic configuration eliminates the technical guesswork: connect your sources, the unit negotiates the SDI format and establishes the link. The flexibility of configurable 1+4 ports allows you to dynamically assign inputs and outputs. You can, for example, define one input for the main feed and another for a video mixer monitor return, all on separate logical paths that are physically unified in the fibre.

The 40km range is made possible by standard SFP+ modules for single-mode fibre, which you select according to your precise wavelength requirements. This modular approach protects your investment against technological change. The RS232 pass-through is critical here: it ensures the continuity of camera control protocols (CCU) over this considerable distance, preserving the precision of remote adjustments.
