Densité 3+ FR1 Frame

Compact 1 RU Frame for Four Modules

The 1 RU Densité 3+ FR1 Frame offers true multiformat operation, with the ability to process simultaneously 3G, HD, SD and analog video, as well as AES and analog audio. The frame provides advanced monitoring and backup capabilities. It can be fitted with 3 RU and 2 RU (using an extender panel) Densité modules. The frame features dual hot-swappable power supplies and fans. The modules for the frame are also hot-swappable. The frame is air-cooled and all modules, redundant PSUs and fans are monitored to provide status via GPI or the Ethernet port. The basic frame configuration includes one PSU and a controller card, which allows card adjustments from the front panel. Front panel multicolor...
