Comtech EFData CDM-625A Advanced Satellite Modem
| Condition: | New OEM |
| Model: | CDM-625A |
| Manufacturer: | Comtech EFData |
The Comtech EFData CDM-625A Advanced Satellite Modem builds on CEFD’s legacy of providing the most efficient and reliable satellite modems. With support for VersaFEC® Forward Error Correction (FEC), the revolutionary DoubleTalkâ Carrier-in-Carrierâ bandwidth compression, additional 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
