Overview
The CDM-650 Satellite Modem is designed for use by foreign government entities that need a modem which employs state-of-the-art modulation and coding techniques to optimize satellite transponder bandwidth usage while retaining backward compatibility with a wide range of Comtech EF Data modems currently in use. The CDM-650 leverages the heritage and feature set of our very successful SLM-5650B/C, CDM-625A and CDM-425 modems. The CDM-650
supports backwards compatibility / interoperability in certain modes of operation with the SLM5650B/C, CDM-625A and CDM-425 modems.
The CDM-650 offers data rates from 18 kbps to 155 Mbps and symbol rates from 32 ksps to 64 Msps (coding / FEC dependent). 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.
Advanced forward error correction (FEC) capabilities are a Comtech EF Data standard feature. Turbo Product Codes (TPC), and three Low Density Parity Check codes (LDPC) families, VersaFEC®-2 high performance LDPCs short and long block and Direct Sequence Spread Spectrum (DSSS) are all supported.
Direct sequence spread spectrum is available to support both point-to-point and point-to-multipoint applications as an option in conjunction with LDPC-based FEC and BPSK. Spreading factors up to 64 are supported. Maximum supported chip rate is 64 Mcps.
Spread spectrum results in operation with ultra-low power spectral densities. This enables use of small antenna apertures when adjacent satellite interference (ASI) is an important consideration.
The IF interface supports 950 to 2000 MHz frequency ranges.
