Broadcast Edge QAM Modulator

Product Details

IPQ6250 is a new generation of modular & high density Edge QAM modulator combining TS-over-UDP/RTP reception, transport stream re-multiplexing, scrambling, PSI/SI processing and 16/32/64/128/256QAM modulation in a 1U rack-mount unit. It supports up to 48 QAM channels by using three external plugged 16 QAM modules, each of QAM modules supporting up to two Gigabit copper interfaces. Moreover, the IPQ6250 supports 1+1 redundant & hot-swappable power supplies for high reliability and stability of system. Its pay-as-you-grow modular design, flexible configurations and licensing mechanism are making the IPQ6250 unparalleled scalability, reliability and system performance to cable operators. The adopts Web browser and SNMP management with remote monitoring and control that can greatly reduce management time and operating expenses (OPEX) of operators.
