A sensing fiber connector is a device used to connect optical fibers in optical fiber sensors or optical fiber sensing systems. Its main function is to detachably connect different parts of optical fiber so that optical signals can be transmitted efficiently and stably between optical fibers. By precisely docking the two end faces of the optical fiber, the optical energy output by the transmitting optical fiber is coupled to the receiving optical fiber to the maximum extent, while minimizing the impact of the connector on the optical link system, such as insertion loss and return loss.

Core features
1. High-precision optical performance
Low insertion loss: Through precision grinding and end face processing, the energy loss of the optical signal at the connection point is minimized to ensure the strength and accuracy of the sensing signal and avoid measurement errors caused by loss.
High return loss: Physical contact or angled contact design is used to reduce optical signal reflection (to prevent reflected light from interfering with the stability of the sensing system
2. High reliability and environmental adaptability
Anti-interference ability: Optical fiber transmission itself is not subject to electromagnetic interference, and the metal parts of the connector can be grounded and shielded, which is suitable for sensing applications in strong electromagnetic environments.
Resistant to harsh environments: Some models use waterproof, dustproof, high temperature/low temperature resistant materials to support IP68 protection level, and can work stably for a long time in humid, corrosive, vibrating or extreme temperature environments
3. Mechanical stability and repeatability
High-strength structure: The connector body is made of metal or reinforced plastic, and the locking mechanism is used to prevent loosening caused by vibration or external force, ensuring the stability of the connection during long-term use.
Repeated plug-in and pull-out consistency: The high-precision size and end face roughness of the ferrule ensure that the insertion loss fluctuates little after multiple plug-ins and pull-outs, meeting the repeatability requirements in long-term monitoring scenarios.
4. Miniaturization and integrated design
Miniaturization structure: For distributed transmission or implantable sensing scenarios, micro connectors are used to adapt to thin-diameter optical fibers to reduce the impact on the measured object.
Multifunctional integration: Some connectors can integrate temperature, strain and other sensing modules, or integrate with fiber gratings, fiber optic gyroscopes and other sensing elements to simplify system wiring.
5. Customized adaptability
Various interface types: Support standard interfaces such as FC, SC, ST, LC, or customize special interfaces according to sensing requirements to adapt to the installation requirements of different sensing systems.
Fiber type compatibility: Compatible with single-mode, multi-mode, polarization-maintaining optical fibers, or special optical fibers to meet the transmission requirements of different sensing technologies.
