Summary

Datum Systems innovation is transforming the SCPC and MCPC modem industry with a new generation modular modem product, the M7 Series, that is versatile, compact, highly efficient and costs less to own and operate. Flexible M7 configurations include a full modem, mod-only, demod-only or multi-demod capability, all using common integrated assembly modules.Standard hardware houses our optional FlexLDPC FEC and many other advanced upgradable features to create the industry’s most spectral and space efficient low cost modem.

Compact Modular Design - The completely new M7 modem hardware platform fits within a half-rack 1 RU space, saving expensive rackspace at the hub or remote sites. Modems can be mounted and operated side-by-side or used in a simple and clean 1:1 redundant configuration. The M7 design uses individual card assemblies for mod, demod, controller and interface for versatile configurations and simple cost effective inventory. The small, lightweight modem saves expensive shipping costs and conveniently fits into a briefcase for easy transportability.

Highly Congurable – The M7 provides a variety of configurations for the user to choose when ordering or as field upgrade options. Options such as data rates, modulation modes, FEC’s and Interface types are all supported and easily upgradable in the field - and without major assembly issues.

Advanced FlexLDPC Onboard – With unparalleled configuration 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.

Sharp Carrier Roll-O Technology – The M7 Series supports advanced filtershaping for optimizied carrier spacing as a standard feature. Datum currentlyoffers down to an 5% Alpha, which means that carriers can be spaced at 1.05times the symbol rate instead of the historical factor of 1.35. This allows an immediate spectral efficiency increase and significant bandwidth savings,at no additional hardware or software cost. Filter Roll-Off options in the newM7 modems Series include 5%, 8%, 10%, 15%, 20%, 25%, 30%, 35% and 40%.See Advanced Filter Shaping White Paper for more information.
