Comtech CDM 625

The CDM-625 Advanced Satellite Modem builds on Comtech EF Data’s legacy of providing the most efficient satellite modems. It is the 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.

The IP Packet Processor enables efficient IP networking and transport over satellite by adding routing capability with very low overhead encapsulation, header compression, payload compression and advanced Quality of Service.

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
  
  

IP Data Encryption
The CDM-625-EN offers IP data encryption capability. Configurable on a per route basis, the modem supports AES data encryption to prevent unauthorized access to data transmitted over the satellite link. AES data encryption is only available for IP traffic processed by the IP Packet Processor.
