Comtech EF Data DMD2050 Satellite Modem (NEW O.E.M)
Manufacturer: Comtech EF DATA / Radyne
Condition: New from original equipment manufacturer
Warranty: as implied by Comtech on its new equipments.
Comtech EF Data’s DMD2050 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) and the IESS-308, IESS-309, IESS-310 IESS–315 & DVB-S commercial standards. 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 16-QAM.
Advanced FEC and modulation capabilities are integrated with the revolutionary DoubleTalkCarrier-in- Carrierbandwidth 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 antenna
• Or, a combination of the above to meet specific mission needs
Data rates range from 2.4 kbps to 52 Mbps and symbol rates range 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 10/100/1000Base-T 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.
