Binary Signal Transmission Across Large Distances via Optical Fiber

Binary Signal Transmission of a Maximum of 12 Signals Across Large Distances via Optical
Fiber by Amplification with Optical Repeater
The application shows the optical connection of an I/O mirror to a serial optical repeater 7XV5461-0Bx00. It
establishes a connection to an optical wide area distance, consisting of 1 or 2 optical fibers. The optical repeat-
er multiplexes or demultiplexes synchronous or asynchronous serial signals of up to 2 optical inputs on an op-
tical fiber remote connection. More information on this matter can be found in the manual of the device
7XV5461.
The optical connection on the remote-side is via LC plugs.
Transmission between the binary signal transmission and repeater takes place interference-free via 62.5
μ
m/
125
μ
m multimode fiber-optic cables. The optical cables are prepared with ST plugs.
The binary signals of the I/O mirror 1 client will transfer only to the I/O mirror 1 server. The binary signals of the
I/O mirror 2 client will as well transfer only to the I/O mirror 2 server.
The repeater has a wide-range power supply unit of DC 24 V up to 250 V and AC 115 V/AC 230 V.
The asynchronous baud rate in the binary signal transmission can be set to 57.6 kbit/s. The repeater has
2 optical 820-nm inputs so that a maximum of 2 binary signal transmissions can be connected. A maximum of
12 binary signals can be exchanged via wide optical fiber connections, for example
permissive overreaching
transfer trip protection of the distance protection
. Additionally, for evaluation purposes, the locations of the
remote circuit-breakers and separators can be transmitted in the local device. This makes the realization of
smart grid applications across large distances possible in order to exchange interference-free binary signals.
