In general, inter-car jumper systems are designed to be a breakout cable between the end walls of the carriage bodies or as a roof or under floor jumper system. Years of experience means that LEONI is able to solve the most complex tasks, whether in terms of the cable construction – consisting of power, data bus, fiber optic or coaxial cable – or in relation to the mechanical design of the cable fixings and guides.

In order to meet the high requirements for flexibility, functionality and durability, we use top-quality materials and specially developed connection systems with suitable connectors and wiring components. We also have a wide range of testing capabilities for development, functionality, reliability and service life testing.
