DEV 4111 Intelligent Universal RF over Fiber Chassis, 2 Slots

DEV 4111 Intelligent Universal RF over Fiber Chassis, 2 Slots 

The DEV 4111 Intelligent Universal Optribution Chassis is a compact 19-inch, 1 RU platform that integrates RF over fiber transmission, L-band amplification, signal distribution and redundancy. Its two front-panel slots accept compatible DEV Optribution optical transmitter, optical receiver or managed amplifier modules.

The chassis can be configured as a standalone optical link, an L-band line amplifier, a 1:8 or 1:16 distribution system, a 1+1 redundant RF over fiber link or a redundant amplifier system. Available 50 Ohm SMA and 75 Ohm precision F female interfaces support a wide range of satellite, broadcast and RF distribution applications.

When equipped with the CPU/controller configuration, the DEV 4111 supports signal monitoring, recording and configuration backup through the DEV Web Interface and SNMP. Redundant AC power inputs and optional automatic switchback or main/backup swapping provide enhanced availability.
