COL5441B  CATV headend CATV Modulator with 4 channel QAM modulator 

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.
