Model D9479 Gigabit QAM Modulator with Dual GbE
With its exciting video transmission technology, the Model D9479 Gigabit QAM Modulator
(GQAM) with Dual GbE packs the broadband pipe with interactive services that your
subscribers want and supports their growing demand for high-definition (HD) content.
Connect directly to current generation video servers, encoders, integrated receiver-decoders
(IRDs), and other digital video sources using the four digital video broadcasting (DVB) standard
asynchronous serial interface (ASI) inputs on the GQAM. Prepare for the future by using the
Gigabit Ethernet (GbE) ports to connect to the next generation of video servers, either linked locally
with the GQAM or remotely through a network.
Make room for other devices in your headend. One GQAM frees up a total of seven additional rack
unit openings. The GQAM contains the core functionality of four Model D9477 MQAM Modulators,
making the GQAM an exceptional product for mass deployment of video-on-demand (VOD),
anything-On-Demand (xOD), and other interactive broadcast services.

Features
Space Savings
●
Contains the core functionality of the MQAM modulator
●
Includes 6 input ports and can provide up to 16 QAM outputs to achieve the broadcast
capacity of 4 MQAM modulators or 16 QAM modulators
●
Enables higher rack density to save space
Network Utilization Enhancements
●
Enables direct connect to both DVB ASI and Gigabit Ethernet video sources at the same
time and the capacity to create transport streams from any combination of the 5 inputs
●
Provides 4 DVB ASI inputs (216 Mbps each) and dual plug-in Small Form-Factor Pluggable
(SFP) GbE inputs for redundancy and to multiplex content from any input to any of the 16
outputs (channels)
●
Uses an output center frequency range of 91 to 999 MHz (use of this increased frequency
range may require a software upgrade)
●
Optimizes system management with provisioning and monitoring by the DNCS
●
Facilitates deployment in either a headend or a hub
