The following are some common methods to reduce the insertion loss of fiber optic connectors:
1. Selecting reliable quality fiber optic connectors is the first step in reducing insertion loss. Quality connectors usually have precise manufacturing process and high quality contact surfaces, which can provide lower insertion loss.
2. The contact surfaces of connectors should be kept clean and clear to avoid interference of optical signals by dust, grease or contaminants. Use appropriate cleaning tools and solvents and follow the manufacturer's instructions for cleaning operations to ensure the quality of the contact surfaces.
3. Accurate alignment of connectors is the key to reducing insertion loss. Ensure precise core alignment and axial alignment to minimize coupling loss of optical signals between connectors.
4. When plugging and unplugging the connector, pay attention to control the plugging and unplugging force to avoid unnecessary mechanical stress and damage. Excessive insertion and removal forces may cause scratches or wear on the contact surfaces, which in turn increases insertion loss.
5. Adapters and compensation fittings can help optimize connector alignment and compensate for axial deviation between fibers, thereby reducing insertion loss.
6. Regularly inspect and maintain the condition of the connectors, including cleaning the contact surfaces, inspecting the connectors for wear and damage, and replacing aged or damaged connectors in a timely manner to keep the connection in good condition.
