GQ-3670
Multi functional Edge QAM Mo
GQ-3670
Multi functional Edge QAM Modulator
Product Overview
GOSPELL’s GQ-3670 is a full IP Based Multi functional Edge QAM modulator, which can receive multiple transport streams from an IP network, and then multiplexing, scrambling as well as insert local information to the transport stream and finally output several adjacent QAM channels by RF interface after QAM modulation. Also, It supports up to 256QAM for maximized channel capacity and utilization.
GQ-3670 supports web browser and SNMP management for local and remote monitoring and controlling that can greatly reduce management time and operating expense (OPEX) of operators. It also supports flexible licensing management functions enabling scrambling functions and expand the numbers of QAM channels, Due to its flexibility and versatility, GQ-3670 can be widely applied to DTV head-end system that are located in core-to-edge TS processing and modulation.
