DEV 7134 Smart RF over Fiber Chassis, 12 Slots

DEV 7134 Smart RF over Fiber Chassis, 12 Slots  

The DEV 7134 Smart Intelligent Optribution Chassis is a compact 19-inch, 4 RU platform providing 12 front-accessible slots for DEV RF over fiber transmitter and receiver modules. Single-link modules support up to 12 optical channels, while twin modules increase system capacity to 16 channels.

With a chassis depth of approximately 255 mm, the DEV 7134 is designed for shallow racks, wall-mounted installations and locations with restricted equipment space. All modules, controllers and power components are accessible from the front for convenient installation and maintenance.

The integrated controller supports permanent signal monitoring, recording and configuration backup through the DEV Web Interface and SNMP. Available 1+1 and 4+1 redundancy configurations, automatic switchback, main/backup swapping and Redundancy Path Gain Compensation provide enhanced availability for mission-critical optical RF links.

• Available functions include:

Automatic switching based on RF sensing

Automatic return to the restored main receiver link

Dynamic main/backup assignment

Mixed standalone and redundant optical modules

4+1 Redundancy

The 4+1 redundancy option uses one backup optical link to protect four main transmitter or receiver links.
