About

The SBM-90X is a telco-grade professional modem designed to provide unparalleled high-throughput for the most demanding applications, supporting Software Defined Networks. This 19-inch rack-mountable unit features an Active LCD front panel for easy configuration, making it suitable for environments requiring vast deployments for both hub-less point-to-point and point-to-multipoint topologies. The SBM-90X offers enormous flexibility and dynamism.

It is SpaceBridge’s Advanced Ethernet L2 Trunking Modem, offering wideband symbol rates up to 125 Msymbols/second. The SBM-90X was engineered with minimal implementation loss to deliver near-theoretical performance for DVB-S2X (EN 302 307-2) across the full range of available high-efficiency MODCOD selections. It can prioritize traffic based on IP DSCP markings, which, in conjunction with its two-way Adaptive Coding Modulation (ACM), ensures high-priority traffic is delivered robustly and efficiently.

Key features include up to 1.47 Gbps aggregate throughput (symmetric 723 Mbps), Ethernet Jumbo frame support, over 1 million packets per second symmetric (2M pps total), Software Defined Network support, indoor 19-inch rack-mountable design, LCD Active Front panel for easy configuration, Layer-2 transparent support, L3 DSCP Quality of Service (QoS) support within L2 stream, and Point-to-Point DVB-S2/S2X with Adaptive Coding and Modulation (ACM).

Use cases include satisfying low to high bandwidth trunks with ACM-enabled S2X carriers, ideal for broadband Internet trunks, community Internet Access Distribution, 3G/4G/LTE/5G aggregation cellular backhaul, mission-critical backup or disaster recovery links, surveillance, government, defense and military applications, GEO applications, dynamic video-stream contribution, and fiber mission-critical backup links.
