Teledyne Paradise Datacom Q-FlexV IF/L-Band Broadcast Satellite Modulator Modem

Teledyne Paradise Datacom Q-FlexV Broadcast Modulator Modem

The Paradise Datacom Q-FlexV broadcast satellite modulator modem replaces the award-winning Vision Series broadcast series. This modem is ideal for Ultra HDTV, DSNG, ISP backhaul, fiber restoration and video contribution and distribution services. 

It supports IP and ASI interfaces, and the DVB-S2X and DVB-S/DSNG standards. The Q-FlexV is a flexible software-defined modem that does what you want, now and in the future. This modem’s flexible hardware platform makes it ideal for handling high-rate video and IP traffic.

Advanced Bandwidth-Efficient Features

The Q-FlexV modem supports the most powerful bandwidth-saving technology available. DVB-S2X, is between 20% and 60% more bandwidth efficient than its predecessor, DVBS2. Paired Carrier+, our recently enhanced carrier overlap technology, overlays transmit and receive carriers reducing the required satellite bandwidth by 50%. 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 bandwidth.

Adaptive Coding and Modulation

Adaptive Coding and Modulation (ACM) uses feedback from the receiver to the transmitter to respond to changes in channel conditions to optimise throughput. By varying the error correction to match atmospheric conditions, link margin is converted into additional bandwidth.

The symbol rate and power to satellite are kept constant, changing the transmitted terrestrial data rate up or down in relation to the current Es/No value. Changes in modcod are transparent at the receiver. ACM works in DVB-S2 and DVB-S2X modes. Deployments of ACM have reported throughput increases of up to 100%.
