Applications

Comtech EF Data’s SLM‑5650A Satellite Modem is designed to comply with the strict requirements defined in MIL‑STD‑188‑165A, modem types I, II, IV, V and VI. Government agencies, the military and commercial networks with demanding performance and/or security requirements commonly utilize this high-end modem for applications on DSCS, WGS and commercial satellites.

The modem provides standard MIL‑STD‑188‑114 (EIA-530 / RS-422), and EIA-613 (HSSI) serial interfaces, and can be optionally configured to support G.703 and Low Voltage Differential Signaling (LVDS) serial interfaces.  It can also optionally be equipped with a 4-port 10/100/1000 BaseT Ethernet Network Processor module that supports switching, routing, and advanced Quality of Service protocols.

The SLM-5650A can be integrated with the Vipersat Management System (VMS) to provide fully automated network and capacity management.  An AES-256 TRANSEC module, compliant with the FIPS-140-2 NIST standard is also available as an option.  All traffic (including overhead and all VMS control traffic) is encrypted when using the TRANSEC module.  

Advanced forward error correction (FEC) capabilities are a Comtech EF Data standard feature. Viterbi, Trellis, Concatenated Reed‑Solomon, and Turbo Product Codes are all supported.

The IF interface supports 52‑88, 104-176, and
950‑2000 MHz frequency ranges.
