DEV 7114 RF over Fiber Distribution Chassis, 16 Slots

DEV 7114 RF over Fiber Distribution Chassis, 16 Slots

The DEV 7114 Intelligent RF over Fiber Distribution Chassis combines optical signal transmission, RF distribution and redundancy management within a compact 19-inch, 4 RU platform. It provides 16 front-panel slots for DEV Optribution modules and four rear slots for integrated RF distribution hardware.

Distribution configurations from dual 1:4 to 1:128 are available with 50 Ohm SMA or 75 Ohm precision F female interfaces. IRD-controlled switch options support 4x16, 4x32, 4x48 and 4x64 L-band configurations, allowing connected receivers to select the required polarization or frequency band.

The integrated controller provides monitoring and control through Ethernet, the DEV Web Interface and SNMP. Available 1+1 and N+1 receiver redundancy, automatic switchback, main/backup swapping and Redundancy Path Gain Compensation help maintain signal availability in mission-critical RF over fiber systems.
