MELVILLE, USA: Comtech Telecommunications Corp. announced that its Tempe, Arizona-based subsidiary, Comtech EF Data Corp., received a $1.3 million order for satellite communications equipment. A leading telecommunications operator will install Comtech's bandwidth-efficient satellite modems to enable cellular backhaul network expansion in South America, a region that is experiencing significant satellite bandwidth shortages.
Specified in the order were the CDM-625 Advanced Satellite Modem and companion redundancy switches. The CDM-625 models ordered include an array of features ideally suited to cellular backhaul applications, including DoubleTalk Carrier-in-Carrier bandwidth compression, Drop & Insert and Low Density Parity Check (LDPC) codes.
DoubleTalk Carrier-in-Carrier is complementary to all advances in modem technology, including advanced forward error correction and modulation techniques. As these technologies approach theoretical limits of power and bandwidth efficiency, DoubleTalk Carrier-in-Carrier, utilizing advanced signal processing techniques, provides a new dimension in bandwidth and power efficiency. When combined with VersaFEC or LDPC/TPC, it can provide unprecedented savings in transponder bandwidth and power utilization.
Fred Kornberg, President and Chief Executive Officer of Comtech Telecommunications, said, "The operator will leverage the globally-proven bandwidth savings features in the CDM-625 Advanced Satellite Modems to reduce satellite-based cellular backhaul operating expenses and to facilitate service expansion in a region that is bandwidth challenged."
