Comtech CDM-625A-EN Advanced Satellite Modem

CDM-625A-EN Advanced Satellite Modem

Overview
The CDM-625A-EN Advanced Satellite Modem builds on our legacy of providing the most efficient satellite modems for IP-centric applications that require data encryption. With support for VersaFEC® Forward Error Correction (FEC), the revolutionary DoubleTalk Carrier-in-Carrier bandwidth compression, additional rolloffs and advanced packet processing, the CDM-625A-EN 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
