The OVT/D-EQAM-6000 is a high-density edge QAM modulator for VOD on-demand services. It receives Gigabit DP/RTP network data input, via de-bounce, re-multiplex, QAM modulation, output after up-conversion, supports up to 24/48/96 independent QAM transmission stream output, frequency range is 54M-1GHz, agile Adjustable (4-way adjacent frequency).

OVT/D-EQAM-6000 This equipment has high integration, high stability and modular design, which greatly reduces space occupation and system construction cost, enabling operators and VOD service providers to launch VOD business effectively in large areas at a lower cost.
