Description
Detailed information

The Comtech EF Data CDM-570A and the Comtech EF Data CDM-570AL are Comtech's next generation satellite modems that provide industry-leading performance and flexibility in a 1 RU package at a very competitive price. With support for VersaFEC® low latency LDPC Forward Error Correction (FEC), the revolutionary DoubleTalk® Carrier-in-Carrier® bandwidth compression, and optimized transmit filter rolloffs, the CDM-570A and CDM-570AL provide 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/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.
