To connect the round connector, prepare the fiber, insert it into the splice tray, secure it, and close the tray to ensure a stable, low-loss connection.

Step 1: Prepare the Fiber Cable

• Remove the outer jacket of the optical cable, including any shielding or armor, to expose the loose fibers .
• Clean and abrade the exposed fibers and strength members using a cleaning solution and sandpaper to ensure a smooth surface for sealing .
• Leave sufficient fiber length (typically around 3 meters) for proper handling and splicing .

Step 2: Insert the Cable into the Splice Box

• Select the correct sealing rings that match the cable diameter and place them on the cable .
• Insert the cable into the designated entry port of the splice box and secure it with a hose clamp or similar fastener .
• Ground the cable shield if applicable, and wrap self-adhesive sealing tape between the sealing rings to prevent moisture ingress .

Step 3: Connect the Fiber to the Round Connector

• Align the fiber ends precisely using a fusion splicer or mechanical splice connector .
• Insert the connector into the slot of the fusion splicing unit or connector holder, ensuring the fiber is properly seated and the electrodes (for fusion splicing) are centered .
• Coil any excess fiber neatly within the splice tray to avoid bending or stress on the fibers .

Step 4: Secure and Close the Splice Tray

• Place the splice protection sleeve over the spliced fiber to protect it from mechanical stress .
• Cover the splice tray and press it to lock in place, stacking additional trays as needed according to the splice box capacity .
• Ensure that trays are stacked securely, following the manufacturer's instructions for alignment and fastening .

Step 5: Final Sealing and Inspection

• Insert sealing strips into the grooves of the splice box to prevent leakage .
• Tighten any valves or grounding screws on the box body.
• Inspect the connection for proper alignment and low insertion loss before completing the installation . Following these steps ensures a secure, organized, and low-loss connection for the round connector in a fiber optic splice box, maintaining the integrity and performance of your fiber network .
