Overview

The DMD2050E Satellite Modem is designed to comply with the widest possible range of U.S. Government and commercial standards and is compatible with the largest number of satellite modems in the industry. It is fully compliant with MIL-STD-188-165A (all terminal types), fully complies with STANAG 4486 Edition 3, as well as the IESS-308, IESS-309, IESS-310 & IESS–315 commercial standards.

The DMD2050E provides highly advanced and bandwidth efficient forward error correction (FEC). Advanced FEC options include Low Density Parity Check (LDPC), Turbo Product Codes (TPCs) and 165B Turbo Codes. 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, 8PSK, 8-QAM, 16-QAM and 16APSK.

Data rates range from 2.4 kbps to 52 Mbps and symbol rates from 4.8 ksps to 30 Msps. The modem provides standard MIL-STD-188-114 (EIA-530 / RS-422), and EIA-613 (HSSI) serial interfaces and 10/100/1000Base-T Gigabit Ethernet interfaces. A dual IF interface supports low IF (52-88, 104-176 MHz), and L-Band (950-2000 MHz) frequency ranges.
