8 in 1 IP input QAM Modulator 

Description

JXDH-6305 IP QAM modulating module is new generation of high-integrated, high-powered QAM modulator. Every module could work separately by the modular design. Each module can receive UDP format TS through gigabyte GE interface, support 10 different IP address or port number, integrate 8 multiplexers with 10 input of each multiplexer and 8 QAM(DVB-C) modulators, each module output 48M~560M neighbor radio frequency carrier through 2 RF output port. Each RF output port has 4 carriers. 1U cabinet support 3 modules (24 route QAM modulating neighbor radio frequency carriers), 4U cabinet support 12 modules(96 route QAM modulating neighbor radio frequency carriers).

It is a good device with high-integrated, high-powered and cost effective, suitable for new generation CATV system. Normally be used in head end or sub-head end.
