On the first day there was an introduction to the basics of fiber optic technology. This laid the foundation for practical applications. On the second day, the participants had the opportunity to learn the basic rules of connector assembly and splicing and were then able to assemble, insert and professionally prepare a splice box. On the third day, the basics were expanded and the OTDR measurement technology explained in more detail by means of measurements and analysis. Here, too, the participants were able to gain experience by creating and analyzing measurements themselves.
