Description

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
