In an age where communication resilience and bandwidth efficiency are paramount, satellite modems play a pivotal role in enabling connectivity across vast and challenging environments. The Comtech CDM-570AL Satellite Modem stands out as one of the most advanced, feature-rich, and flexible solutions in the satellite communication landscape. Developed by Comtech EF Data, this next-generation modem caters to enterprise networks, mobile operators, maritime users, government operations, and more.
At VSATPlus, we are proud to offer the CDM-570AL, a modem that doesn’t just meet expectations but exceeds them with powerful performance, adaptive technologies, and robust management capabilities. Whether you’re looking to reduce OPEX, improve throughput, or achieve carrier-grade reliability, this is the modem designed to support your mission-critical networks.
The CDM-570AL belongs to Comtech’s renowned 570 series and represents an enhancement in capability and design over its predecessors. It is a 1RU rack-mountable modem, offering L-Band IF, a wide data rate range (2.4 kbps to 10.239 Mbps), and highly flexible modulation and FEC options.
What sets it apart is support for DoubleTalk® Carrier-in-Carrier®, a patented Comtech technology that enables transmit and receive carriers to overlap in frequency, allowing optimal spectrum usage. With VersaFEC® and VersaFEC-2 for low latency and high coding gain, plus advanced compression, QoS, and ACM features, it delivers cutting-edge satellite connectivity for modern IP-centric applications.
Here’s a breakdown of the core features that make the CDM-570AL an industry leader:
Whether you're deploying for offshore rigs, enterprise backhaul, or emergency communications, the benefits of this modem include:
Its ability to deliver high throughput with reduced spectrum means better performance at lower operational costs.
With FAST code upgrades, the modem can evolve with your network needs – adding features like DoubleTalk, higher data rates, or advanced FECs on the fly.
Operating from 0°C to 50°C, it’s built for use in tough field conditions. The unit is also equipped with excellent thermal stability and internal diagnostics.
Optional AES-256 encryption ensures secure transmission of sensitive data.
With SNMP, Telnet, CLI, and web interfaces, network operators can manage hundreds of units easily through Vipersat Management System (VMS).
