The Q-FlexV™ broadcast satellite modulator/ modem is ideal for Ultra HDTV, DTH, DSNG, ISP backhaul, fiber restoration and video contribution and distribution services. It supports IP and ASI interfaces, and the DVB-S2/S2X and DVB-S/DSNG standards.
The Q-Flex’s flexible hardware platform now provides point-to-point and point-to-multipoint operation in one unit. The Q-Flex modem is ideal for handling IP traffic but can be fitted with virtually any type of terrestrial interface and operates at up to 200Mbps.
The Q-FlexV modem supports the most powerful bandwidth-saving technology available. Paired Carrier™ overlays transmit and receive carriers reducing satellite bandwidth by 50% (using ViaSat’s patented PCMA technology).
Compared to DVB-S2, the new DVB-S2X standard improves bandwidth efficiency for consumer DTH services by up to 20% and by up to 60% for professional broadcast services. ClearLinQ™ adaptive transmit pre-distortion compensates for linear and non-linear distortion in the communications channel. DVB-S2X ACM converts any unused link margin into additional throughput and provides 100% link availability.
