In the dynamic world of satellite communications, operators and enterprises require modems that can deliver high-performance data transmission with exceptional reliability and flexibility. The Comtech CDM-570 and CDM-570L Satellite Modems are engineered to meet these demands, offering a robust solution for a wide range of applications, including enterprise networks, mobile backhaul, disaster recovery, and offshore communications.
At VSATPlus, we proudly offer the Comtech CDM-570 and CDM-570L series modems—products trusted by satellite service providers and enterprises worldwide. With cutting-edge features, superior forward error correction (FEC), versatile interfaces, and integrated IP capabilities, these modems empower organizations to achieve maximum network efficiency and reliability.
The CDM-570 and CDM-570L are entry-level, cost-effective satellite modems built in a 1 RU chassis. While the CDM-570 is suited for IF frequencies in the 50 to 180 MHz range, the CDM-570L supports L-Band frequencies from 950 to 2000 MHz. Designed to serve low-cost terminals and IP-based satellite applications, they come equipped with data interfaces such as EIA-530, V.35, G.703, and optional 10/100Base-T Ethernet.
Both models offer symmetrical and asymmetrical operation, fast acquisition, Automatic Uplink Power Control (AUPC), redundancy options, and support for mesh, star, and hybrid network topologies.
With support for data rates from 2.4 kbps to 9.98 Mbps and independent TX/RX configuration, the modems allow bandwidth-efficient operation in both symmetrical and asymmetrical scenarios. This makes them suitable for diverse use cases such as video streaming, VoIP, SCADA, and mobile communications.
The modems support various modulation types—BPSK, QPSK, OQPSK, 8PSK, patented 8-QAM, and 16-QAM—and advanced FEC options like Turbo Product Code (TPC), Viterbi, and Reed-Solomon. These enable excellent bandwidth optimization and reliable performance under varied satellite link conditions.
The optional IP Module in the CDM-570-IP and CDM-570L-IP models delivers robust IP networking capabilities including static IP routing, header and payload compression, IGMP multicast support, and VLAN tagging. This enhances performance and bandwidth savings for IP-centric applications.
The modems support comprehensive management interfaces such as SNMP, web GUI, Telnet, and front-panel control. Network administrators benefit from features like event logging, remote configuration, software upgrades, and modem monitoring.
With multi-level QoS and compression capabilities, the modems reduce jitter and latency for real-time applications, prioritize mission-critical traffic, and significantly reduce required satellite bandwidth.
Operators can upgrade to Vipersat mode, enabling dynamic SCPC allocation and bandwidth-on-demand. This is ideal for shared satellite links and ensures optimal performance during peak load or application-specific demands.
Operating across a wide temperature range (0 to 50°C), the modems come in a compact rack-mountable 1 RU chassis and offer reliable performance in demanding environments.
The CDM-570 and CDM-570L modems are versatile solutions for:
