Feature: 1. EASY TO CONNECT: The fiber optic adapter allows for convenient and seamless connection between fibers. Perfect for improving efficiency and performance. 2. LOW INSERTION LOSS: With a tight axial pressure at the fiber optic junction point, the space between the two fiber end faces is minimal, resulting in minimal link loss often ≤0.3db. 3. SUITABLE FOR COLD CONNECTIONS: The fiber optic adapter performs well in various cold environments, ensuring consistent performance and being able to withstand extreme temperatures. 4. REUSABLE: The fiber optic adapter is designed for repeated use, providing long service life and reducing the need for frequent replacements. 5. FAST INSTALLATION: The pre embedded fiber optic adapter offers low insertion loss, excellent repeatability, and quick installation speed, saving time and effort.
