DEV 7113 Intelligent RF over Fiber Indoor Chassis, 20 Slots

DEV 7113 Intelligent RF over Fiber Indoor Chassis, 20 Slots

The DEV 7113 Intelligent RF over Fiber Indoor Chassis is a high-density, modular platform for housing and managing DEV Optribution optical transmitters, receivers and signal-processing modules. Its compact 19-inch, 3 RU chassis provides 20 front-panel slots and supports up to 40 RF over fiber channels when equipped with twin modules.

The DEV 7113 accommodates analog RF over fiber modules, CWDM and DWDM equipment, EDFAs, optical splitters, optical switches and Ethernet media-converter modules. Available 50 Ohm and 75 Ohm cabling options support SMA, F and BNC female RF interfaces.

The integrated controller provides monitoring and control through Ethernet, the DEV Web Interface and SNMP. Configurable 1+1 and N+1 redundancy options, automatic switchback, main/backup swapping and redundancy-path gain compensation help maintain continuous signal availability in mission-critical fiber transmission systems.
