QAM Modulator

The DC1000 (4RU chassis) and the DC1100 (1RU chassis) are the most flexible professional QAM modulator solution on the market. With multiple input options, built in multiplexing functionality, full PSI/SI regeneration customized for the cable network and a built in intuitive WEB GUI makes the QAM modulator

the ideal solution for deployments requiring aggregation of services from multiple sources, service processing and preparation for QAM broadcast over cable networks.








Flexible QAM solution for cable networks

The QAM Modulator module is part of the platform. It is a compact solution generating 16 QAM frequencies for Cable Networks. Based on a full digital-modulation and up-conversion architecture, the QAM Output module delivers a clearer signal giving the best possible performance. The DC1000/DC1100 can be provided with IP, ASI, DVB-S/S2, DVB-T and DVB-C input and the QAM module can be combined with the decoder modules and FM radio modules in the same chassis making it possible to manage both digital services and analogue services from one common platform through a single user interface
