The CDM-625A Advanced Satellite Modem builds on our legacy of providing the most efficient satellite modems. With support for VersaFEC® Forward Error Correction (FEC), the revolutionary DoubleTalk® Carrier-in-Carrier® bandwidth compression, lower rolloffs and advanced packet processing, the CDM-625A provides significant savings under all conditions. This combination of advanced technologies enables multi-dimensional optimization, allowing satellite communications users to:
-
Minimize operating expenses (OPEX)
-
Maximize throughput without using additional transponder resources
-
Maximize availability (margin) without using additional transponder resources
-
Minimize capital expenses (CAPEX) by allowing a smaller BUC/HPA and/or antenna
-
Or, a combination to meet specific business needs
AES Data Encryption
Configurable on a per route basis, the modem supports AES data encryption for transmission security to prevent unauthorized access to data transmitted over the satellite link. AES data encryption is only available for IP traffic processed by the Packet Processor.
Environmentally Resistant Model
The CDMER-625A is the Environmentally Resistant (ER) version of the CDM-625A. It offers added protection in more aggressive operating environments that have a higher concentration of dust, sand and salt. The ER version uses an application of Urethane Conformal Coating (CC) and critical interface protective covers for enhanced protection against dust, sand and salt.
