How to connect the base station optical module to the pigtail fiber

To connect a base station optical module to a pigtail fiber, use a pre-terminated fiber pigtail and perform either fusion or mechanical splicing to link the bare fiber end to the module's optical port.Step-by-Step Connection Process1. Identify the Optical Module and Pigtail Type Determine the type of optical module in the base station (e.g., 10G SFP+, 25G SFP28) and the corresponding fiber pigtail connector type (SC, LC, FC, or ST) to ensure compatibility . Check whether the module uses single-mode or multimode fiber and the required wavelength (e.g., 850nm VCSEL for multimode). 2. Prepare the Fiber Pigtail A fiber pigtail has one pre-terminated connector and one bare fiber end . The connector end will plug directly into the optical module, while the bare fiber end will be spliced to the base station's fiber infrastructure. Ensure the pigtail is clean and free of dust or debris. 3. Clean the Connector and Module Port Use fiber optic cleaning tools to clean both the pigtail connector and the optical module port. Proper cleaning reduces insertion loss and prevents signal degradation. 4. Splice the Bare Fiber EndFusion Splicing: Align the bare fiber end of the pigtail with the base station fiber using a fusion splicer. The splicer melts the fibers together, creating a low-loss, permanent connection .Mechanical Splicing: Alternatively, use a mechanical splice to join the fibers if a fusion splicer is unavailable. This method uses a precision alignment sleeve to hold the fibers in place. 5. Connect the Pigtail to the Optical Module Insert the pre-terminated connector end of the pigtail into the optical module port. Ensure it clicks or screws in securely depending on the connector type (e.g., LC push-pull, SC snap-in, FC screw-type), . 6. Test the Connection After connecting, use an optical power meter or OTDR to verify signal integrity and check for excessive loss. Proper testing ensures the connection meets network performance standards. 7. Secure and Protect the Fiber Route the pigtail carefully to avoid bending or stress. Use fiber management trays or protective tubing to prevent damage and maintain long-term reliability .Additional TipsAlways match the fiber type (single-mode or multimode) and connector type to the optical module specifications.Avoid touching the fiber endfaces to prevent contamination.Label the pigtail and module port for easy identification in the network. By following these steps, the base station optical module can be reliably connected to the pigtail fiber, ensuring minimal signal loss and stable network performance .
