New Entry-Level Satellite Modems from Comtech EF Data

Comtech EF Data Corp. announced today the introduction of two new entry-level satellite modems, the CDM-570A and CDM-570AL. These next generation models provide industry-leading performance and flexibility in a 1RU form factor. While the units are priced very competitively, they offer tremendous value via an innovative feature set.

The CDM-570A and CDM-570AL are the first Comtech EF Data modems in the entry-level category to support DoubleTalk Carrier-in-Carrier bandwidth compression, VersaFEC® low-latency LDPC advanced Forward Error Correction and optimized transmit filter rolloff. DoubleTalk Carrier-in-Carrier is based on Raytheon Applied Signal Technology’s patented “Adaptive Cancellation” technology, which allows transmit and receive carriers of a duplex link to share the same transponder space. Also available with these new modems is optimized transmit filter rolloff, specifically 5%, 10%, 15%, 20%, 25% and 35%. The combination of technologies enables multi-dimensional optimization and can provide over 50% bandwidth savings when 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 OPEX savings of DoubleTalk Carrier-in-Carrier,” said Daniel Enns, Senior Vice President of Comtech EF Data.

Given the feature set and value, the CDM-570A and CDM-570AL Satellite Modems are geared toward a range of users, including enterprise, ISPs, satellite service providers, offshore, maritime and mobile operators. As the products continue to evolve, additional functionality and options to optimize networks will be available.

Comtech EF Data is now accepting orders for the CDM-570A and CDM-570AL Satellite Modems. For additional detail on the product, visit
