QMultiFlex-400 IP Modulator/Multi-Demodulator Satellite Modem

Overview

The QMultiFlex-400™ hub offers an affordable solution for point-to-multipoint satellite IP
communications. The Hub supports a highlyefficient DVB-S2/X shared outbound along with up to 16 DVB-S2/X returns.
In addition, the QMultiFlex-400 unit supports an embedded Hub Canceller utilising the powerful DVB-S2 and DVB-S2X waveforms, allowing satellite carriers in a point-to-multipoint system to operate in the same satellite bandwidth, providing satellite BW savings of up to 50%.
The QMultiFlex-400 hub system may be expanded to support a maximum of 128 remote sites. This is achieved by cascading Multi-demodulators at the hub, where each Multi-demod supports an additional 16 SCPC receive carriers into the hub.
All network modems (and other equipment) can be monitored and controlled via Q-NET™ Navigator (included as standard).

Why QMultiFlex-400?
Historically, networks required separate boxes for modulators, demodulators, IP optimisers, Ethernet switches, routers, packet encapsulators, spectrum analysers, oscilloscopes, redundancy controllers.

The QMultiFlex-400 replaces all of these, at a significant cost savings even before considering the cost of spares, training and maintenance for all those individual boxes. And these savings can be multiplied as you scale your network.
