Signal and communication system--MVB/WTB cable assemblies

Multifunctional vehicle bus (MVB) and wired train bus (WTB) cable assemblies are specifically designed for communication cables in train control networks (TCN).Through these cable assemblies, the T-bus structure with MVB cables can be used to disconnect the bus interface from the control unit without interrupting the entire bus communication.There are 4 black jumpers on the component. 2 * 100nF test capacitor can be able to work by disable the 2 * 120Ω resistor by pulling out the corresponding jumper.The wires are connected through a proven anti-vibration cage clamp terminal.These MVB / WTB series interfaces have two 30 °sockets in parallel, all metal housings, and have good EMC protection.Each cable assembly can be assembled according to the actual vehicle signal design and the corresponding cable and related accessories are assembled. The entire set of components is used in accordance with the track industry standards.
