Problems solved by technology

Because metal conductors will generate a certain bit error rate during transmission, and the transmission speed is relatively slow, an additional shielding layer needs to be added to the outer layer of the harness to prevent adjacent cables from generating magnetic fields and interfering with each other

Embodiment Construction

[0006] After the fiber optic cable is laid, align the tip of the laser pointer with the pinhole of the socket at one end of the fiber cable, press the button, the laser pointer will emit laser light, and the light emitted by the laser pointer will be transmitted through the optical fiber, corresponding to the other end of the socket. According to the circuit diagram, it can be seen that the corresponding pinhole position has light, which proves the correctness of the optical fiber installation and the integrity of the optical fiber.

Abstract

The invention relates to an optical fiber aligning process method. The method is characterized by comprising the following steps that: after an optical fiber cable is laid, a pen head of a laser pen is aligned to a socket pinhole at one end of the optical fiber cable; a button is pressed down, the laser pen emits laser, and the laser emitted from the laser pen is transmitted by an optical fiber; and if light at a corresponding pin position is visible from a socket pinhole position corresponding to the other end of a socket, the installation accuracy and the integrity of the optical fiber are proved. In the method, the optical fiber is used as a signal transmission medium, is accurate in transmission and has high transmission speed. The method is applied to the Australia EDI626 project, and an extremely good field using effect is achieved.

Description

technical field [0001] The invention relates to the technical field of rail passenger car manufacturing, in particular to an optical fiber calibration test process applied to the Australian EDI626 project. Background technique [0002] Generally, the cables of vehicles can be divided into power cables and signal cables according to their functions. The power cables provide various levels of voltage required by the electrical appliances on the vehicle, and the signal cables transmit the instructions issued by the vehicle central control system to each electrical appliance. In previous projects, the cables with two functions used metal conductors as the transmission medium, and the method of checking whether the cable installation was correct was to use a cable calibration device with a metal conductor inside and a buzzer for calibration. Because metal conductors will generate a certain bit error rate during transmission, and the transmission speed is relatively slow, an addit...
