DEV 1953 Universal Multi-Channel Switch Chassis, 3 RU

DEV 1953 Universal Multi-Channel Switch Chassis, 3 RU

The DEV 1953 Universal Switch Chassis is a modular 3 RU platform for RF, optical and digital-video switching and redundancy applications. The chassis provides eight standard module slots and can be expanded to 12 or 16 slots, allowing multiple independent switching and signal-distribution channels within one enclosure.

Available modules include DPST A/B switches, RF-sensing switches, passive splitters/combiners, optical switches and ASI/SDI switching or distribution modules. Depending on the installed modules, the system supports CATV, L-band and broadband RF signals up to 2500 MHz, optical wavelengths from 1260 to 1610 nm and digital formats through 3G-SDI.

Automatic RF-sensing control, optional switchback, main/backup reassignment and SNMP trap-based switching make the DEV 1953 suitable for mission-critical redundancy systems. Ethernet, RS-232, SNMP and the DEV Web Interface provide flexible integration with professional monitoring and control platforms.
