: 1. Applicability: Suitable for any combination of 0.25mm optical fiber and 0.9mm optical fiber. 2. Simple operation: The operation is simple and quick, no fixture tools are required, and the required time is short. 3. Good airtightness: Box structure design, good airtightness, not easy to lose the liquid, and strong weather resistance. 4. Applicable mode: V groove docking technology is adopted, which is suitable for single-mode and multi-mode fiber connections. 5. Low installation requirements. It does not rely on the flatness of the fiber end face cutting, which greatly reduces the requirements for the proficiency of the operator.
