Comtech Telecommunications Corp. Expands Satellite Modem Product Line
New CDM-650 Satellite Modem provides state-of-the art modulation & coding to optimize satellite bandwidth usage
“We are pleased to introduce the new CDM-650 Satellite Modem to address the needs of foreign government and military entities,” said
The CDM-650 Satellite Modem was purpose-built for secure government and military networks. The CDM-650 is suited for fixed location, on-the-pause and on-the-move communications applications. The product features Turbo Product Codes, three Low Density Parity Check (“LDPC”) code families, VersaFEC®-2 high performance LDPC short and long block forward error correction and a range of modulation, including BPSK, QPSK, OQPSK, 8PSK, 8-QAM, and 16-QAM. By employing the combination of state-of-the-art forward error correction and modulation techniques, the CDM-650 can optimize satellite transponder bandwidth usage.
In addition, Direct Sequence Spread Spectrum (“DSSS”) is an option on the CDM-650 for supporting both point-to-point and point-to-multipoint applications in conjunction with LDPC-based forward error correction and BPSK. The combination of advanced features provides ultra-low power spectral densities, enabling the use of small antennas when adjacent satellite interference is an important consideration.
The CDM-650 offers data rates from 18 kbps to 155 Mbps and symbol rates from 32 ksps to 64 Msps. The modem supports an Ethernet 10/100/1000T user traffic data interface that can be used in Bridge mode or Routed mode offering Quality of Service protocols and traffic shaping / congestion control methods. In addition, the modem supports backward compatibility and interoperability in certain modes of operation with Comtech’s SLM-5650B/C, CDM-625A and CDM-425 modems.
