AMS701 8xIP to 8xDVB-C modulating module

AMS701 8xIP to 8xQAM modulating module is new generation highly modular and high performance QAM modulator. This modulator use modular design, each modulating module can work separately. Each modulating module can receive IP TS input use UDP format through GE port, max support 10 different IP address or port number, integrated 8 sets multiplexers with 10 inputs, and 8 sets QAM (DVB-C) Modulator, and can output 110MHz to 860MHz adjacent frequencies, each RF output has 4 carriers. 1U case max support 3 modules (24 QAM), 4U case max support 12 modules (96 QAM). This equipment is highly assembled, high performance with low cost, quite suitable for new generation CATV system.
