GOSPELL Cable TV Modulator

Product Overview:

 

GOSPELL’s GQ-3680 is a new generation of modular & high density IPQAM combining TS-over-UDP/RTP input and output, transport stream re-multiplexing, scrambling, PSI/SI processing and 16/32/64/128/256QAM modulation in an 1RU. It supports up to 48 or 72 QAM modulation channels by using three external pluggable 16 or 24QAM channel modules, each QAM module supporting up to two Gigabit copper interfaces. Moreover, GQ-3680 supports 1+1 redundant & hot-swappable power supplies for high reliability and overall stability of the system. Its pay-as-you-grow modular design, flexible configuration and licensing mechanism are making the GQ-3680 extremely scalable, very reliable with high performance, all of which are important to cable operators.

 

The GQ-3680 supports Web browser and SNMP management with remote monitoring and control that can greatly reduce management time and operating expenses (OPEX) of operators.

 

With GQ-3680, cable operators can be ensured that they will have a scalable, reliable product that enables them to offer high performance video stream services for years into the future. It can be used in cable central head-ends, remote head-ends and VOD networks.
