How to insert the optical module into the baseband board

To connect an optical module to a baseband board, insert the module into the SFP port, connect the optical fiber, secure the puller, and properly manage the cables.Step-by-Step Connection Procedure1. Prepare the Optical Module and FiberRemove the dust-proof cap from the optical module and the optical fiber connector to prevent contamination .Ensure the optical fiber is clean and free from bends or kinks that could affect signal quality . 2. Insert the Optical ModuleLower the puller on the optical module.Carefully insert the optical module into the designated SFP port on the baseband board (e.g., SFP0/SFP1) until it clicks into place .Raise the puller to lock the module securely. 3. Connect the Optical FiberPlug the FE/GE optical fiber into the port on the optical module.Ensure the fiber is fully seated and aligned with the module interface to maintain proper signal transmission .For outdoor connections (e.g., RRU/AAU), use an outdoor quick-lock connector to protect the fiber and prevent stress on the single-core cable . 4. Cable ManagementRoute the optical fiber along the cabinet or tower structure, avoiding sharp bends and mechanical stress .Use optical fiber binding straps to secure the cable according to the BBU cable claw positions.Install a winding pipe at the end of the optical fiber between the connector and the first binding point to prevent strain and maintain proper bend radius . 5. Verify the ConnectionCheck that the optical module is fully seated and the fiber is properly connected.Ensure that the cable is not under tension and that all protective measures (binding straps, winding pipe) are in place . 6. Optional: Ethernet or GPS ConnectionsIf the baseband board also requires Ethernet or GPS clock signal connections, connect the RJ45 or SMA connectors as specified in the installation guide . Following these steps ensures a secure, reliable optical connection between the baseband board and the optical module, maintaining signal integrity and protecting the fiber from mechanical damage. Proper handling and cable management are critical for long-term performance, especially in outdoor or high-traffic environments .
