The CDM-425 Advanced Satellite Modem continues to build on our legacy of providing the most efficient and reliable satellite modems. It offers the most popular and powerful features of the CDM-625A, with a smaller footprint and less power. Its Forward Error Correction options comprise 18 VersaFEC® ModCods and 74 VersaFEC-2 ModCods, permitting the user to optimize for latency and coding gain for any link budget. It includes DoubleTalkCarrier-in-Carrierbandwidth compression, additional TX rolloffs and sophisticated packet processing capabilities. 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
