DEV 1951 Universal Switch Chassis, Dual-Channel 1 RU

DEV 1951 Universal Switch Chassis, Dual-Channel 1 RU

The DEV 1951 Universal Switch Chassis provides two independently configurable module slots in a compact 19-inch, 1 RU enclosure. Its modular architecture supports RF, broadband, optical and digital-video switching applications, allowing one chassis platform to serve a wide variety of signal-routing and redundancy requirements.

Available modules include DPST A/B switches, RF-sensing switches, transfer switches, passive splitters/combiners, optical switches and ASI/SDI distribution or switching modules. Depending on the selected module, the DEV 1951 supports electrical signals from DC to 18 GHz, optical wavelengths from 1260 to 1610 nm and digital formats through 3G-SDI.

Automatic signal-based switching, optional switchback and main/backup reassignment support reliable redundancy configurations. The DEV Web Interface, SNMP and Ethernet-based control protocols simplify integration into professional monitoring and control systems.
