CDM-570A/L, CDM-570A/L-IP & CDM-570A/L-IPEN Satellite Modems

The CDM 570A, CDM-570AL and CDM-570A/L-IPEN are our 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-2 high performance LDPC and 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 bandwidth savings. 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. The CDM-570A/L-IP includes a high-performance packet processor for IP-centric applications.

3xDES Data Encryption
Configurable on a per route basis, the modem supports 3xDES data encryption for transmission security to prevent unauthorized access to data transmitted over the satellite link. 3xDES data encryption is only available for IP traffic processed by the Packet Processor.
