DEV 7134 RF Over Fiber Indoor Chassis
DEV 7134 RF Over Fiber Optic System
The DEV 7134 is a 4 RU chassis providing 12 Slots for RF over Fiber transmit and receive modules of theoptribution chassis. OPTRIBUTION is a registered trademark of DEV Systemtechnik and comprises RF signal transmission products for the Optical Transmission and Distribution of RF Signals. The product family covers transmission from RF to optical and from optical to RF between antenna and receiver. series. With its redundant power supplies and the built-in controller all functionalities are accessible and to monitor via the Web Interface or the SNMPSimple Network Management Protocol (SNMP) is a remote protocol used for managing devices in M&C Systems. Protocol. All control is front panel accessible; the chassis becomes the SMART Intelligent Optribution Chassis.

Option 28 Automatic Switch Back
Automatic switch back enables the autonomous switch back from the redundant link to the main link
based on the RF sensing functionality.
Available in combination with 1+1 Rx redundancy options, only
Option 55 Change Ethernet to optical Ethernet Interface; 30 km
Option 56 Change Ethernet to optical Ethernet Interface; 1530 nm; 100 km
Option 57 Change Ethernet to optical Ethernet Interface; 1550 nm; 100 km
With Option 55, Option 56, or Option 57 the CPU module of the device provides a 100Base-FX
Ethernet interface with SC/PC connectors (instead of the standard 100Base-TX Ethernet interface
with RJ-45 connector) for the optical transmission of Ethernet signals.
