Overview
The CDM-625 Advanced Satellite Modem builds on our legacy of providing the most efficient satellite modems. It was our first modem to combine advanced Forward Error Correction (FEC) such as VersaFEC and Low Density Parity Check (LDPC) codes with the revolutionary DoubleTalk Carrier-in-Carrier bandwidth compression, allowing for maximum savings under all conditions.
