GQ-3650DR

 

All-In-One DVB-C QAM Modulator

 

Product Overview

 

      GQ-3650DR is a high density and all-in-one multi functional QAM modulator devolped by GOSPELL. It combines RF receiving & demodulation, TS re-multiplexing, scrambling and QAM modulation into 1RU, and provides two kinds of RF demodulation options; either QPSK/8PSK or QAM demodulation can be selected according to operators’ needs. Moreover, the GQ-3650DR supports up to eight channels of input transport streams from ASI interfaces. Therefore, with this product, operators obtain lower cost expenditure, lower energy consumption and minimized space of racks occupied. This all comes from the benefits of GQ-3650DR’s high density and all-in-one design.

 

      GQ-3650DR adopts GOSPELL’s flexible licensing mechanism for scrambling function and numbers of QAM channels. Cable operators can easily enable up to four QAM channels and four DVB SimulCrypt CAs by importing the license file which is provided by GOSPELL. This flexibility brings operators lower capital expenditure (CAPEX) not only today but also tomorrow.

 

      GQ-3650DR supports both Web browser and SNMP management for remote monitoring and control in real time. This can significantly reduce management time and operating expense (OPEX) for operators. Due to its flexibility and versatility, the GQ-3650DR can be widely applied to DTV central headend and remote headend system.
