Datum M7L & M7LT L-Band Sat-Modem with High Speed DVBS2X

Datum Systems M7L & M7LT DVB-S2X High-Speed L-Band Modems

The Datum Systems M7L and M7LT are high-performance L-Band satellite modems supporting DVB-S2 and DVB-S2X waveforms for fixed, mobile, mesh, and point-to-multipoint SATCOM networks. Operating from 950–2150 MHz (with optional IF operation), these modems deliver data rates up to 350 Mbps using advanced modulation up to 64APSK and ultra-low roll-off factors down to 5%. With full ACM support, optional Smart Carrier Cancelling, integrated BUC/LNB power, and a high-stability 10 MHz OCXO reference, the M7L/M7LT platform maximizes spectral efficiency while reducing latency and operational cost.
