GQ-3680A

Modular Edge QAM Modulator

1: IP QAM Modulator

2: Multiplexing and srcambling function to save more equipment

3: IP based Modualtion optional

Product Overview

GOSPELL’s GQ-3680A is a new generation of modular & high density Edge QAM modulator combining TS-over-UDP/RTP input and output, transport stream re-multiplexing, scrambling, PSI/SI processing and 16/32/64/128/256QAM modulation in a 1U rackmount unit. It supports up to 48 QAM channels by using three external pluggable 16 QAM modules, each QAM module supporting up to two Gigabit copper interfaces. Moreover, GQ-3680A 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-3680A 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-3680A, 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.
