Comtech Satellite Modem



The CDM-570A and the CDM-570AL 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 multidimensional 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 EIA232 and G.703 T1/E1 data interfaces. The CDM-570A/L-IP include a high-performance packet processor for IP-centric applications.
