MuxLab - 500734 SM10 Extendeur 6G-SDI sur fibre avec canal retour SM 10 km

How do you maintain this vital link, this technical dialogue of images, sound and data? The MuxLab 500734 extender with return channel on single-mode fibre provides the technically elegant answer. It opens up two paths on the same optical highway: one for your main 4K feed to the control room, the other for the return feed, talkback and control signals to the camera. This native bidirectionality transforms a simple extension into a true professional production link.

Ten kilometres is no longer just a comfort distance, it's a real geographical separation. On single-mode fibre, the signal stands up to this test without flinching. The key? Standard SFP+ modules that you choose according to the wavelength and power required. The device manages the essentials: it automatically recognises the SDI format (HD, 3G, 6G) and configures the directional ports according to your diagram. These configurable 1+4 ports offer rare agility: you define which input is used as a return, which output relays the programme, and so on.

RS232 pass-through is not an option, it's an absolute necessity at this scale. It ensures that the camera control unit (CCU) travels intact, allowing focus and iris adjustments to be made from the control room as if the technician were on the cameraman's shoulder. The solid, fanless aluminium chassis ensures that these sensitive electronics withstand the conditions of outdoor installation.
