The fiber optic detector can evaluate the quality of fiber optic connection by detecting the loss of optical signal. The following are its specific methods, performance advantages and structural features:
Methods for testing the quality of fiber optic connection
Insertion loss detection
Connect the red laser light source transmitting end of the fiber optic detector to one end of the fiber optic connection point to be tested, and connect the optical power meter or the receiving end of the fiber optic test pen to the other end of the connection point. The 650nm red laser pen emits a highly visible red laser light as an optical signal of a specific wavelength and power.
After the optical signal is transmitted through the fiber optic connection point, the optical power value is measured by the receiving end or the optical power meter. By comparing the transmitted optical power and the received optical power, the insertion loss of the fiber optic connection point can be calculated. Generally speaking, the lower the insertion loss, the better the quality of the fiber optic connection. If the insertion loss exceeds the specified standard value, it indicates that there is a problem with the connection point, such as loose connection, uneven fiber end face, dust or impurities, etc.
Return loss detection
The fiber optic detector emits an optical signal into the optical fiber, and then detects the intensity of the optical signal reflected back from the fiber optic connection point. Return loss reflects the reflection of the optical signal at the fiber optic connection point, which is related to factors such as the end face quality of the connection point and the concentricity of the optical fiber.
A higher return loss value indicates that the connection point has less reflection of the optical signal and the connection quality is better; conversely, if the return loss value is low, it means that there is a large reflection at the connection point, which may cause reflection interference of the optical signal and affect the performance of the optical fiber communication system.

Cutting auxiliary positioning
In the cutting process of metal, plastic and other materials, the red dot projected by the 680nm red laser diode module can clearly indicate the cutting path, helping operators to align the knife quickly and accurately, ensure the cutting position accurate, and reduce material waste.
Welding position guidance: In welding operations, especially for electronic component welding or precision metal welding with high precision requirements, the 680nm laser module can provide accurate welding position markings, so that welders can more accurately control the welding trajectory, improve welding quality, and avoid problems such as false welding and leaking welding.
Drilling positioning: When drilling holes in various materials, the 680nm red dot laser module can pre-mark the drilling position to ensure that the drill bit is accurately aligned with the target, improve the accuracy and consistency of drilling, and play an important role in some small hole processing with high precision requirements, such as micro-hole processing of aerospace parts.
