How to connect the fiber distribution box and the fiber splicing box

To connect a fiber distribution box to a fiber splicing box, you splice the incoming distribution fibers to pigtails in the splicing box, protect the splices in trays, and route the fibers carefully to maintain bend radius and signal integrity.Step-by-Step Connection Process1. Prepare the Fiber CablesStrip the outer jacket and coating of the fiber cables using a fiber stripper to expose the bare fiber cores .Clean the fiber ends with lint-free wipes and isopropyl alcohol to remove dust and contaminants .Cleave the fibers with a precision fiber cleaver to create smooth, perpendicular end faces for optimal splicing . 2. Splice the FibersFusion Splicing: Use a fusion splicer to weld the distribution fiber to a pigtail, ensuring minimal insertion loss and high reliability .Mechanical Splicing: Align the fibers in a mechanical splice connector if a fusion splicer is unavailable; this method is faster but may have slightly higher loss .Protect each splice with a splice sleeve and place it in a dedicated fiber splice tray inside the splicing box . 3. Route and Secure FibersCoil any excess fiber in the splice tray or within the distribution box to maintain the standard bend radius and prevent microbending .Use cable management features in both boxes to avoid entanglement and ensure easy access for maintenance . 4. Connect to the Distribution BoxIf the distribution box uses pigtails, plug the spliced pigtail connectors into the adapter ports of the distribution box .For splitter-ready boxes, ensure the PLC splitter is installed and the fibers are routed correctly to the output ports . 5. Test the ConnectionVerify signal integrity using an OTDR (Optical Time Domain Reflectometer) or power meter to ensure low loss and proper alignment .Label each fiber and port for future maintenance and troubleshooting .Best PracticesAlways maintain the minimum bend radius to prevent signal loss.Keep fibers clean and avoid touching the bare cores.Use factory-made pigtails when possible to reduce field errors.Ensure the boxes are mounted securely and protected from environmental factors if outdoors . By following these steps, the fiber distribution box and splicing box will be properly connected, ensuring a reliable and maintainable fiber optic network.
