The system’s innovative, high performance architecture features an integrated DVB-S/S2 Receiver and a Turbo Product Coding (TPC) Single Carrier Per Channel (SCPC) Modulator. The combination of a shared, high speed outbound DVB-S/S2 carrier and TPC for the low latency data return channel facilitates efficient IP networking and transport over satellite. Packaged in a carrier-grade 1RU platform, the CDM-740 Satellite Modem saves rack space and simplifies remote management compared to two box solutions. Optimized for high-speed packet processing and reliability, it uses an embedded central processing unit, real time operating system and flash data storage. The CDM-740 offers dual Gigabit Ethernet interfaces and is available in modem and demodulator only configurations. The system transmits industry-standard TPC up to 9.98 Mbps. The receive side supports DVB-S and DVB-S2 operation at L-Band up to 62 Msps. To optimize the use of bandwidth, the CDM-740 supports DVB-S2-based Constant Coding & Modulation (CCM) and Variable Coding & Modulation (VCM) operation. While both modes of operation deliver efficiencies compared to DVB-S, VCM further increases user capacity or reduces the overall bandwidth required by the network.
