Optical Fibre Interface, MDRC

Product code: GHQ6050053R0001
Used to couple two sections of an ABB i-bus line using an optical fibre link in order to bridge longer distances or to avoid having to implement lightning and overvoltage protection when laying cables between buildings.

Description

The device is used to couple two sections of an EIB line using optical Fibres in order to bridge greater distances and to reduce the amount of lightning and overvoltage protective equipment when laying cables across buildings. An EIB power supply must be provided for both EIB sections.

Two devices are required to set up a transmission link. These are connected to an existing optical fibre installation by means of a 2 m long patch cable (included with supply). Signals are transmfitted by two optical fibres that are suitable for transferring 850nm signals. It is also possible to connect them directly with prefabricated standard cables.

The data flow is displayed separately for the optical fibre input and output using an LED.
