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