The SatLink 1910 is the leading high-performance DVB-RCS certified VSAT Indoor Unit, with support for DVB-S2 and DVB-S forward links. Hardware optimized for IP networking it offers outstanding throughput and upgrades to new hardware-based features. Advanced QoS, traffic acceleration, VPNs and many other value-added software features make the SatLink 1910 ideal for carrier-class interactive data, voice, and video conferencing, plus multicast IP applications. Users connect via Ethernet. The SatLink 1910 supports various antenna options plus BUCs/LNBs in C, Ku, Ka and EHF bands, including STM’s own Ku Band transceivers.
Outstanding IP Performance
SatLink 1910 delivers 18 Mbps of IP throughput with advanced IP networking features.
Bandwidth Efficiency at Many Levels
Advanced DVB-S2 modulation and FEC, header compression, section packing & intelligent bandwidth-ondemand algorithms enable efficient broadband applications; the unit consumes only 64 bps when idle, 0 bps in "auto-sleep" mode.
Comprehensive IP Networking Features
SatLink delivers TCP and HTTP acceleration, VPN, NAT, and VLAN options, plus a built-in DHCP server and both unicast and multicast IP routing.
Advanced QoS for Data, Voice, Video
QoS Groups for bandwidth-on-demand enable delay sensitive traffic for interactive media concurrently with bulk data, without dedicating bandwidth per VSAT.
Low-Power, 1U Rack-Mount Design
The SatLink The SatLink 1910's compact size with low power consumption makes it viable for all types of locations, including remote, solar-powered sites.
Accessory Card Slot for Upgrade Options
Rear plug-in card slot allows advanced new features, such as mesh networking, providing a future-proof VSAT investment.
ACM and Rain Fade Mitigation
Adaptive Coding and Modulation (ACM) on forward links and adaptive FEC and symbol rate on return links increase bandwidth efficiency and improves link margins to mitigate rain fades.
Mobile and Transportable Options
The SatLink 1910 and SatLink Hub Systems support options for marine and land mobile VSAT requirements.
