Comtech CDM-570

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

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 CDM570AL 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 include a highperformance packet processor for IP-centric applications.

More about Comtech Advanced VSAT Platform

Advanced VSAT Solutions is a portfolio of high-performance, satellite-based communication solutions that facilitate premium services for the enterprise – energy, mining, maritime, airline and corporate networks. Representing the next generation in satellite networking equipment, the Advanced VSAT comprises a bundle of products and advanced technologies.

Today, end users require astounding levels of additional throughput to support mission-critical applications. The majority of this increased demand originates in the inbound direction given the valuable multimedia content that needs to be transmitted from remote sites back to central locations. It is key for satellite networking solutions to be able to handle these increasing data rates while having headroom for future growth.

Advanced VSAT is focused on throughput and service quality. It has the processing power needed to support your pps and Mbps transmission requirements for high data rate applications, high definition video and voice. It provides the service quality your users demand with low jitter and low latency so you can meet those stringent SLAs. It is also a fully managed system with the intelligence to enable dynamic allocation of bandwidth when and where it is needed.

  • Services and Equipement for Advanced VSAT
  • With ourSCPC (Single channel per carrier) Service Satellite bandwidth is dedicated to a single source.
  • dSCPCprovides dynamic SCPC (dSCPC) bandwidth management of space segment
  • Time division multiple access (TDMA)allows several users to share the same frequency channel by dividing the signal into different time slots.
  • We offer high Quality VSAT Solutions
