PSM-500L Datum Systems L-Band Satellite Modem

The Datum Systems PSM-500L Series L-Band Satellite Modems are the industry's most reliable and flexible modem in its class with multiple external BUC supply options for easy field configurability. The PSM-500L is unmatched by any other modem for its BER performance, fast acquisition, low latency and total power/bandwidth optimization.

With unparalleled confguration flexibility and superior coding gain, FlexLDPC takes FEC 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.

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.

The PSM-500L provides an optional external BUC capability for maximum power flexibility, swappable voltage and power options. LNB power is standard from an integrated power supply. A High Stability 10 MHz reference is also provided through the modem Transmit (N-Type) and Receive (F-Type) connections at the rear. Reference, BUC and LNB power may be disabled via the front panel. Front panel voltage and current measurements are available for BUC and LNB monitoring.

The PSM-500LT 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 29.5Mbps.

Built-in 1:1 redundancy comes standard on the PSM-500LT and supports BUC/LNB power and reference switching. It can be enabled through the front panel and requires only a few external cables and power splitters.
