1.2 Applications
1.2.1 Example of applications
With the help of the binary signal transducer 2 binary signals can be
detected and directly transmitted over FO distances up to 3 km via
multimode cables and can be put out in the remote station via relay
contacts. A repeater 7XV5461 is available for transmission with mono-
mode fibres up to 100 km (fig. 2a).
Transmission can, however, also be carried out via modem or PCM
devices (fig. 2b) after connecting the equipment to the RS232 interface.
