Datum Modem M7 IF or M7L L Band Modular Satellite Modems

Description

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.

Datum Modem M7 IF or M7L L Band Modular Satellite Modems Features:
Compact Modular Design – The completely new M7 modem hardware platform fits within a single half-rack 1 RU space, or two modems mounted side-by-side, saving expensive rackspace at the hub. The M7 design uses individual card assemblies for mod, demod, controller and interface for versatile configurations and simple cost effective inventory.

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 Filter Roll-Off – The M7 Series supports advanced filter shaping for optimisied carrier spacing as a standard feature. Datum currently offers down to an 5% Alpha, which means that carriers can be spaced at 1.05 times 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.

Smart Carrier Canceller – Smart Carrier is a patented advanced second generation carrier canceller which allows 2 similar carriers to occupy the same transponder spectrum, but is different from other cancellers in that it is a baseband canceller instead of an IF canceller. It allows excellent performance with easy setup and no additional cabling. Smart Carrier is compatible with all Datum modulation types and FECs, and is well suited to be used with Sharp Roll-Off factors all the way down to 5%. Datum’s technique provides improvement in the Shannon Capacity of ~ 2 dB, which is ~50 % increase in the fundamental channel capacity.
