Installation of 24-core fiber optic splice box

Installing a 24-core fiber optic splice box involves careful cable preparation, splice tray setup, fiber organization, and secure closure to ensure reliable network performance.Step 1: Prepare the Fiber Cable

• Remove the outer jacket of the fiber optic cable according to the manufacturer's instructions, exposing the loose tubes and strength members. Leave approximately 3 meters of cable for preparation and splicing .
• Clean and abrade the exposed fibers and cable sheath using a cleaning solution and sandpaper to ensure proper sealing and adhesion .
• Strip the buffer tubes to expose individual fibers, typically around 130 cm (51 inches) for splicing .

Step 2: Install the Cable into the Splice Box

• Select appropriate sealing rings for the cable diameter and place them on the cable.
• Insert the cable into the designated entry port of the splice closure.
• Ground the cable shield if applicable, and wrap self-adhesive sealing tape between the sealing rings to create a secure seal .
• Secure the cable to the base of the closure using a hose clamp or other fastening mechanism .

Step 3: Set Up the Splice Tray

• Open the splice tray cover carefully to avoid compressing fibers .
• Install the splice organizers: for heat-shrink fusion splices, use the long rubber organizer; for mechanical splices, use the plastic organizers provided .
• Attach buffer tubes to the strain-relief points on the tray to prevent fiber movement .

Step 4: Organize and Route Fibers

• Lay service loops at a defined length to maintain bend radius limits.
• Sort fibers according to the connection plan, using fiber guides and intermediate fixings to prevent slippage .
• Ensure proper bending radius to avoid signal loss or fiber damage.

Step 5: Splice the Fibers

• Fusion splicing: Align fiber ends in a fusion splicer and create a molecular bond using an electric arc (~2000°C), .
• Mechanical splicing: Use precision guides and index gel to align fibers without heat .
• Install splice protection sleeves over each splice to protect against mechanical stress and moisture .

Step 6: Close and Secure the Splice Box

• Replace the splice tray cover carefully, ensuring fibers are not pinched .
• Snap or slide the closure cover into place, aligning tabs and notches correctly.
• Check all seals and fasteners to ensure the closure is weatherproof and mechanically secure .

Step 7: Test and Document

• Measure attenuation and verify all splices meet quality standards.
• Document fiber routing and splice locations for future maintenance . Following these steps ensures a secure, organized, and high-performance installation of a 24-core fiber optic splice box, protecting the integrity of your network connections.
