Comtech EF Data CDM-625A-EN Advanced Satellite Modem with AES Encryption
Includes AES Data Encryption, L-Band TX: 10 MHz reference for BUC, FSK communications and optional BUC power supply
CDM-625A-EN Advanced Satellite Modem with AES Encryption
The Comtech EF Data CDM-625A-EN features AES Data Encryption for IP traffic and highly advanced bandwidth efficient technologies that deliver massive spectral savings. With support for the revolutionary DoubleTalk Carrier-in-Carrier bandwidth compression, VersaFEC Forward Error Correction (FEC), additional rolloffs and advanced packet processing, the CDM-625A-EN provides exceptionally reliable spectral purity and satellite space segment cost reductions under all conditions. These combinations of advanced technologies enable 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/amplifier and/or antenna
Or, a combination to meet specific business needs
The modems are available with 70/140 MHz or L-Band IF and EIA-530/-422, V.35, sync EIA-232 and G.703 T1/E1 data interfaces. The CDM-625A-EN includes a high-performance packet processor for IP-centric applications.
