ITTH GmbH & Co. KG relies on hybrid connectors from the Fischer FiberOptic Series for data transmission in the high-performance scanning systems used for the automatic optical inspection of brake shoes on Danish State Railways. Thanks to high-performance camera systems, the scanning systems installed in the track bed at the stations in Odense and Kolding take photos of the brake shoes as the trains pass over them. Subsequent transmission to the computer system takes place at a speed of 10 Gbit/s via hybrid connectors from the Fischer FiberOptic Series. Since the system is located in the track bed, the connectors need to be suitably robust and resistant to external influences. The Fischer connectors have IP68 and IP67 sealings. They are resistant to external influences such as dust, rain and snow. Even oil and gasoline, that they may also come into contact with in the track bed, cannot harm the connectors.
