SFT308A 8 in1 IP Mux-QAM module is the latest generational QAM modulator with high integrated level and performance. The modular design of this device makes each of its daughter cards stand-alone when operating. Besides, each daughter card can receive the UDP format TS through GE port, furthermore, it supports up to 256 different input address (IP address and port No). This device is combined 8 multiplexers with 256 channels inputs and 8 QAM (DVB-C) modulators, which can output adjacent channel RF carrier(30M~860M)through the two RF output interface (4 carriers for each). Additionally, the 1 U chassis for this modulator supports up to 3 modules (24 channels QAM) while the 4U chassis supports up to 12 modules (96 channels QAM). This DX308A 8in1 IP QAM modulator has excellent integrated level, powerful performance and low cost, which is special adequate for the new generation CATV system.
