Specifications

1. Support 16 ASI input
2.Support 4 channels multiplexing, 4 channels scrambling and 4 channels QAM modulating

Outline

 

COL 5441B QAM Modulator with MUX is a high performance and cost-effective ASI mux-scrambling QAM modulating device latest designed by Company, Which provide 16 ASI input interface. After 4 channels multiplexing, scrambling and QAM modulating process, then it gives 4 RF output (4 adjacent frequencies by 1 RF port). The device is characterized with high integrated level, high performance and low cost. This is very adapting to newly generation CATV broadcasting system.
