MVB (Multifunctional Train Bus) cable
(MVB (Multi-Function Vehicle Bus) cable is installed in the rolling stock to connect the fixed part and is used to transmit digital signals with a baud rate of 10M. The communication system within the locomotive uses cables based on the bus system and is suitable for control, detection instruments, diagnosis TCN standard (train communication network standard). The bus system consists of railway bus WTB (stranded train bus) and road bus MVB (multifunctional vehicle bus), connected through several gateways.)
