CDM-760 Trunking and Broadcast

The CDM-760 Advanced High-Speed Trunking Modem builds on our award-winning family of high-speed, ultra efficient trunking modems. The CDM-760 further enhances our offerings to include ultra wide band symbol rates, near theoretical performance with minimal implementation loss, our proprietary DVB-S2 Efficiency Boost technology, Super Jumbo Frame (SJF) Ethernet support and many other value-added features.

The CDM-760 Advanced High-Speed Trunking Modem was designed to be the most efficient, highest throughput, point-to-point trunking modem available. The CDM-760 accommodates the most demanding Internet Service Provider (ISP) and telco backhaul links by offering users the most advanced combination of space segment saving capabilities while minimizing the need for unnecessary overhead.

The CDM-760 offers an expansive range of symbol rates (100 ksps to 150 Msps) and data rates (100 kbps to 314 Mbps). In a duplex setting, this is a staggering 628 Mbps or 300 Msps. The onboard Ethernet interfaces support Super Jumbo Frames from 64 Bytes to >10,000 Bytes and will process Ethernet frames at a blazing > 1.2 Million packets / second. With the optional Packet Processor card installed the CDM-760 can support > 350,000 packets per second while performing simultaneous Header Compression and QoS.

Expanding on the efficient DVB-S2 EN 302 307 standard, the CDM-760 again furthers spectral efficiency with its DVB-S2-EB1& EB2 (Efficiency Boost) waveforms. DVB-S2 is widely accepted as the most spectrally efficient standards-based waveforms. With our Efficiency Boost technology (DVB-S2-EB1& EB2), you can achieve a 10% – 35% increase in efficiency over the DVB-S2 standard without an increase in power or occupied bandwidth. The CDM-760 accomplishes this task by virtually doubling the number of available MODCODs, introducing three new ROF figures (5%, 10% and 15%) and minimizing implementation loss to near theoretical operation. The CDM-760 is software upgradeable to support future standards including DVB-S2 Efficiency Boost and DVB-S2X. All waveforms are interoperable with the CDM-760 DPD (Dynamic Pre-Distortion). DPD allows satellite amplifiers to push further into saturation, maximizing transponder efficiency. The pre-distortion function is constantly optimized by the modem and does not require any user intervention.
