APPLICATION
This cable is primarily used for communication systems within rail vehicles such as trains, fixedly installed to connect devices and realize control, monitoring, and diagnostic functions. The system is based on the TCN standard and employs two types of buses, WTB (Train Communication Bus) and MVB (Multifunction Vehicle Bus) , interconnected through redundant gateways to ensure high reliability of the system .
