Application examples
Area of application
Die DDLS 170 optical data transmission units are used wherever transmission devi-
ces using different systems are more elaborate, complicated, susceptible to interfe-
rence, and expensive to operate and maintain.
Optical data transmission units replace e.g.:
·
Collector wires
·
Trailing cables
·
Radio connections
When used in mobile applications, the travel speed and acceleration do not influen-
ce the transmission quality of the data.
In the application of optical data transmission, a distinction is made between
·
Coupling to bus systems
·
Point-to-point connections

Examples of use (in principle)
One data path - horizontal
For example, for controlling transport trucks
Fig. 6: Transport truck
Two data paths - horizontal
Fig. 7: Two transport trucks running run after the other
When arranging several transmission paths one after the other, the transmission
frequencies must be alternated in order to prevent mutual interference (see Fig. 7).
