Designed with carrier-grade robustness and forward-thinking technologies, the CDM-760 is engineered to meet the bandwidth-heavy demands of today’s ISPs, telcos, mobile operators, and government networks. At VSATPlus, we’re proud to offer this market-leading modem to our global clients, ready for integration into your most challenging network deployments.

🔍 Product Overview

The CDM-760 is the pinnacle of Comtech’s high-speed trunking modem series. It enhances the performance of traditional DVB-S2 waveforms with DVB-S2 Efficiency Boost (EB1 & EB2), features ultra-wide symbol rate capabilities (100 ksps to 150 Msps), and provides blazing throughput up to 314 Mbps simplex / 628 Mbps duplex.

Designed to support IP trunking, G.703, disaster recovery, and real-time video streaming, this modem is especially effective in point-to-point architectures. It reduces satellite bandwidth consumption with technologies like DoubleTalk Carrier-in-Carrier®, Adaptive Coding and Modulation (ACM), and Dynamic Pre-Distortion (DPD).

🚀 Key Features

• Efficiency Boost: Up to 35% greater spectral efficiency over traditional DVB-S2 via EB1/EB2 MODCODs and roll-off optimizations.
• DoubleTalk Carrier-in-Carrier®: Overlay TX and RX carriers within the same bandwidth to drastically reduce satellite OPEX.
• Adaptive Coding & Modulation (ACM): Real-time adaptation to link conditions for higher throughput and reliability.
• Header Compression & QoS Engine: Enables high packet-per-second performance while maintaining low latency and jitter.
• DVB-CID MetaCarrier: Advanced interference mitigation via embedded unique carrier ID.
• Super Jumbo Frame & Packet Processor: Supports over 1.2 million packets per second, handles header compression, routing, and QoS prioritization.
• Redundancy Options: Supports 1:1 and 1:N redundancy configurations for fault tolerance.
• Multiple Interface Support: Ethernet, Optical, G.703, SDH, and SONET options available.
• Carrier-Class Design: Full metal 1RU chassis, advanced cooling, industrial temperature support, and compliant with major telecom standards.

🛠️ Applications

• ISP Trunking: Maximize data capacity with spectral and link optimization to reduce operating costs.
• Telco Backhaul: Reliable and efficient data aggregation from remote sites to central exchanges.
• Disaster Recovery: Rapid-deploy modem for mobile command units and emergency field stations.
• Government & Defense: Secure, encrypted, and high-throughput satellite links for command and control networks.
• Enterprise Networks: Dedicated corporate WAN backbones using SCPC or carrier aggregation techniques.

⚙️ Technical Specifications (Summary Table)

📈 Performance Highlights

The CDM-760 supports ACM/CCM, SCPC, and DVB-S2-EB2 to deliver optimal throughput regardless of weather, interference, or link degradation. With DoubleTalk Carrier-in-Carrier®, operators can overlay transmit and receive signals, conserving spectrum and achieving >50% bandwidth savings in some scenarios.

Its packet processor can compress VoIP streams by up to 70%, accelerating throughput for codecs like G.729 from 31.2 kbps to just 9 kbps.

Further, GZIP compression delivers real-time payload reductions of up to 59%, especially useful in data-heavy applications like cloud access or media delivery.

🧩 Network Flexibility

The CDM-760 supports both Layer 2 (bridged) and Layer 3 (routed) modes, with up to 256 static routes and 150,000 PPS duplex in routing mode. This flexibility means the modem can be deployed as a managed edge router, traffic shaper, or simple transport gateway.

🔐 Security & Control

Security is reinforced with 256-bit AES link encryption, full SNMPv3 management, and in-band monitoring/control over satellite. The unit also supports automatic uplink power control, dynamic pre-distortion, and remote software upgrades for zero-touch deployments.
