[Via Satellite 04-24-2014] Comtech EF Data announced two new entry-level satellite modems, the CDM 570A and CDM 570AL. These models will support VersaFEC low-latency LDPC advanced Forward Error Correction, DoubleTalk Carrier-in-Carrier bandwidth compression and optimized transmit filter rolloff.

DoubleTalk Carrier-in-Carrier is based on “Adaptive Cancellation” technology, as created by Raytheon, which permits transmit and receive carriers of a duplex link to share transponder space. This combination of technologies has the ability to improve bandwidth efficiency by more than 50 percent compared to legacy modems.

“With the release of the CDM 570A and CDM 570AL, users with lower data rate links can now more cost-effectively leverage the CAPEX and OPESX savings of DoubleTalk Carrier-in-Carrier,” said Daniel Enns, senior vice president of Comtech EF Data.
