Products Overview
SFT3348T is a high performance and cost-effective DVB-T modulator designed by Softel. It has 8 DVB-S2 tuner inputs, after multiplexing, scrambling and modulating process, then it gives 4 RF output. To meet customers' various requirements, this device is also equipped with 128 IP input and 4 MPTS output over UDP and RTP. Its pluggable structure design greatly facilitates the change of modules as needed. Moreover, the four CAMs/CIs accompanied can descramble the programs input from 8 Tuner inputs. SFT3348T can be upgraded and controlled through network system, which allows it to be widely used in setting up digital broadcasting network and provide good signals for scientific laboratory and DVB-T STB.
