Datum Systems PSM-500 IF-Band Satellite Modem
Space Communication Transport Specification (SCPS-TP) compatible
PSM500 70 or 140 MHz IF-Band Satellite Modem
Datum Systems manufactures highly versatile and efficient satellite modems. This high performance 70/140 MHz Satellite Modem, the PSM-500, is the industry's most reliable & flexible modem in its class and is unmatched by any other modem for BER performance, fast acquisition, low latency and total power/bandwidth optimization. The PSM-500 can be configured in mod and demod-only modes to support point-to-multipoint architectures at a hub or gateway site.
Advanced FlexLDPC -With unparalleled configuration flexibility and superior coding gain, FlexLDPC takes FEe technology innovation to the next level, bringing strong economic advantages to satellite service providers and their customers. Granular code rates and block sizes get you the most out of your available satellite bandwidth and spectral power, while keeping processing latency at the desired level. Other optional FEC types include Viterbi, Trellis, Reed Solomon and Turbo Product Codes.
SCPS TCP/IP Acceleration -Datum Systems provides an embedded protocol acceleration option based on the Space Communication Transport Specification (SCPS-TP). Our integrated optimization software provides increases in IP packet throughput over TCP/IP links via our Ethernet IP interface option.
Backward Compatibility
Datum System's PSM-SOO implementation represents state of the art enhancements to the popular legacy PSM-4900 series of modems, while being completely backward compatible.
Easy Feature Unlocks
The PSM-SOOLT can be easily upgraded via front panel key codes. Upgrades are simple to implement and are available in preconfigured software versions, offering a variety of options for modulation, FEC and data rates up to 29.SMbps.
Redundancy
Built-in 1:1 redundancy comes standard on the PSM-SOOLT and supports BUClLNB power and reference switching. It can be enabled through the front panel and requires only a few external cables and power splitters.
