By Mark Anderson, railway market manager-North America Transit authorities are challenged by the complexity of decisions and multiple system designers involved in modern train-to-ground communications. As PTC systems evolve to CBTC systems, the system must interact with other communications and passenger information systems. This poses a unique challenge for rapid-moving communications infrastructures with elements that may be above or underground. Any single communications infrastructure may require knowledge and experience with low frequency databus cables, fiber optic cables, or radio frequency cables and wireless antenna systems. HUBER+SUHNER is the only company with global experience across all three areas of LF, FO and RF technology, in hundreds of installations, with continuous state-of-the-art development in the specific areas of need for the railway industry. The passive communications infrastructure of the train could require a CAT7 copper cable 10 Gigabit jumper, a fiber optic cable backbone or RF antenna wireless bridge between cars. Train-to-ground systems must be designed to rigorous electrical, environmental and fire safety standards that assure operation in extremes of cold, heat and moisture. Train control and communications systems designers may be looking at only one aspect of the system, or fail to take into account components that must withstand difficult challenges of weather, service life, and vibration. Transit authorities and system designers want to assure that a system will achieve peak performance in highly variable conditions over a long service life. HUBER+SUHNER can work with transit authorities, system designers, integrators and construction/installers in all aspects of a system’s lifecycle to provide support in achieving the maximum performance of the passive components of the communications system. In short — HUBER+SUHNER has the expertise to help transit authorities and system designers reach decisions faster for robust performance of their systems.
