Modulator CDH9000-DEC-16T-SCQM16

CDH9000-DEC-16T-SCQM16 is a high performance and cost-effective QAM modulator. It has 16 DVB-C FTA tuner input to 16 non-adjacent carrier output with multiplexing, scrambling and QAM modulating included. It also supports maximum 512 IP input port and one IP (MPTS) output through GE1 and TS input for re-mux through 2 ASI ports.
It is also characterized with high integrated level, high performance and low cost. It supports dual power supply (optional). This is very adaptable to newly generation CATV broadcasting system.
