The DMD2050 provides highly advanced and bandwidth-efficient forward error correction (FEC). Advanced FEC options include Turbo Product Codes (TPCs) and Low Density Parity Check (LDPC). Legacy support for Viterbi, Trellis, Concatenated Viterbi Reed-Solomon, and Sequential FEC are also included. A complete range of modulation types is supported including BPSK, QPSK, OQPSK, 8-PSK, 8-QAM, and

Advanced FEC and modulation capabilities are integrated with the revolutionary DoubleTalk® Carrier-in-Carrier® bandwidth compression allowing for maximum state-of-the-art performance under all conditions. This combination of advanced technologies enables multi-dimensional optimization, allowing satellite communications users to:

  • Minimize required satellite bandwidth
  • Maximize throughput without using additional
    transponder resources
  • Maximize availability (margin) without using
    additional transponder resources
  • Enable use of a smaller BUC/HPA and/or
  • Or, a combination of the above to meet
    specific mission needs

Data rates range from 2.4 kbps to 52 Mbps and symbol rates from 4.8 ksps to 30 Msps.

The modem provides a standard MIL-STD-188-114 (EIA-530 / RS-422), serial interface. It can optionally be configured with EIA-613 (HSSI), G.703 (T1/E1/T2/E2 & T3/E3), DVB ASI/SPI and 10/100/1000 BaseT Ethernet Interfaces. Drop & Insert functionality is supported on the G.703 interface.

A dual IF interface supports low IF (52-88, 104-176 MHz), and L-band (950-2000 MHz) frequency ranges.

Cost-effective, ultra-high reliable systems are enabled in conjunction with the RCS-11 1:1 redundancy switch, and/or the RCS-20 M:N redundancy switch.
