Datum M7LT L-Band Mesh Satellite Modem with 16 Demodulators

Datum M7LT L-Band Mesh Satellite Modem with 16 Demodulators 

The Datum Systems M7LT Mesh is a compact L-band mesh satellite modem that combines one SCPC modulator with as many as 16 independent demodulators in a single 1RU chassis. Designed for SCPC mesh, point-to-multipoint and hybrid mesh networks, it provides an efficient platform for satellite hubs and remote terminals.

The M7LT Mesh supports transmit data rates up to 39 Mbps and aggregate receive data rates up to 75 Mbps. FlexLDPC forward error correction, Adaptive Coding and Modulation, AUPC and carrier roll-off factors as low as 5% help optimize bandwidth utilization and maintain reliable links under changing conditions.

All transmit and receive channels connect to the LAN through an integrated five-port Gigabit Ethernet Layer 2 bridge. Additional Datum M7D multi-demodulator units can be added when more receive channels are required.
