While the orders specify a range of different products, the anchor product for all three orders is the CDM-625 advanced satellite modem with DoubleTalk Carrier-in-Carrier, said Comtech Telecommunications.
According to the company, the CDM-625 Advanced Satellite Modem builds on Comtech EF Data’s legacy of providing satellite modems. It is the first modem to combine Low Density Parity Check (LDPC) codes with DoubleTalk Carrier-in-Carrier bandwidth compression allowing for maximum savings, claims the company.
Carrier-in-Carrier is based on Applied Signal Technology’s DoubleTalk bandwidth compression technology. DoubleTalk uses Adaptive Cancellation, a patented technology that allows the transmit and receive carriers of a full-duplex satellite link to be transmitted in the same transponder space. When combined with advanced forward error correction and modulation techniques, DoubleTalk Carrier-in-Carrier can deliver operating expense savings.
Fred Kornberg, president and CEO of Comtech Telecommunications, said: Our CDM-625 modem with DoubleTalk Carrier-in-Carrier continues to be adopted globally by service providers. The bandwidth efficiencies provided by the revolutionary DoubleTalk carrier-in-carrier technology are being leveraged to address satellite capacity challenges.
Comtech EF Data manufactures a broad spectrum of satellite communications products, including Satellite Modems, Bandwidth & Capacity Management, TCP/IP Performance Enhancement Proxies, Encapsulators, Receivers, Converters, Amplifiers, Transceivers and Terminals.
