Do you know how to use a fiber optic red light pen?

In the environment of integrated network wiring, in order to meet the needs of high-performance wiring, optical fibers often appear bare fiber, disc fiber, optical fiber splicing, etc., because optical fibers are fragile compared to copper wires, and are prone to failure, so optical fiber detection tools have become a common tool in integrated network wiring, optical fiber red light pen as one of the commonly used optical fiber detection tools to troubleshoot network faults, can quickly detect optical fiber connectivity and optical fiber failure points, so do you really understand optical fiber red light pen? In addition to detecting optical fiber failure points, what are the uses of fiber optic red light pen? How to use a fiber optic red light pen?

• Lasers are harmful to the eyes, so when using a red light pen, avoid direct laser exposure to the eyes;
• When using an optical fiber red light pen, it is best to use a cleaning tool to clean the optical fiber jumper interface;
•  Generally, the service life of lasers will be shortened in high-temperature working environments, so red light pens should try to avoid high-temperature working environments;
• After using the red light pen or not using it for a long time, wear a dust cap in time to avoid dust, oil and other contamination;
• In order to prevent the battery from rotting and damaging the red light pen, please remove the battery in time when the red light pen is not used for a long time.
