Round-head flange fiber connections typically involve the use of round-head flange (FC)-type fiber optic connectors, which have a threaded sleeve to secure and seal the fiber. Here are the steps to connect the flanged fiber:
Prepare the fiber: Make sure the ends of the fiber are straight and clean. Fiber optics can be cut using a fiber cutting knife, and dust from the ends of the fiber can be removed using a fiber cleaning tool.
Fiber cutting: Use a specialized fiber cutting tool to cut a clean, flat cutting surface at the end of the fiber to ensure a good insertion and connection.
Fiber polishing: Use a fiber polishing kit to polish the ends of cut fibers to the proper finish for low-loss connections.
Insert the fiber: Carefully insert the polished fiber into the slot of the Type FC connector until it touches the alignment post inside the flange.
Secure the fiber: Use a dedicated fiber crimping tool to crimp the fiber inside the connector to ensure that the fiber is fixed inside the connector and will not move.
Installing the Flange Sleeve: Insert the connector with the fiber into the round head flange sleeve and screw it by hand. Make sure the connector is fully inserted into the flange sleeve and that the threads are properly aligned.
Final fixation: Use a special wrench or other tool to tighten the flange sleeve according to the torque value recommended by the connector manufacturer to ensure the mechanical stability of the connection and good sealing.
Inspection and testing: After completing the joint, you should check whether the joint is neat and undamaged, and whether the connection is firm. Test the insertion loss of the connector with an optical power meter to ensure that the connection loss is within an acceptable range.
Throughout the process, care should be taken to keep the fiber clean and avoid any contamination that could lead to loss or reflection of the optical signal. If you are not familiar with the fabrication process of fiber optic connectors, it is recommended to perform it by an experienced technician to ensure the quality of the connection.
