Square Optical Cable Splice Package

A square optical cable splice box can be made by constructing a durable enclosure, organizing fiber splices with trays, and ensuring proper protection and strain relief for the fibers.

Materials and Tools Needed

Enclosure material: Plastic, polycarbonate, or metal sheet for the box walls and cover. Fiber splice trays: To hold fusion or mechanical splices securely. Cable entry/exit ports: Grommets or cable glands for environmental sealing.

Adhesives or screws: For assembling the box. Strain relief clamps: To prevent fiber stress. Optional: Weatherproof sealant if the box is for outdoor use.

Step-by-

Step Construction

Design the BoxCut four equal panels for the sides and one panel for the base to form a square shape. Ensure the internal dimensions allow for fiber trays and bend radius protection (typically 30–50 mm minimum bend radius for single-mode fibers).

Assemble the Enclosure

Join the side panels to the base using screws, adhesive, or welding (for plastic/metal). Attach a removable cover to allow access for maintenance.

Prepare Cable Entry and Exit

Drill holes for incoming and outgoing fiber cables. Install grommets or cable glands to protect fibers from sharp edges and environmental exposure.

Install Fiber Splice Trays

Place trays inside the box to hold fusion or mechanical splices. Arrange fibers in loops to maintain proper bend radius and prevent stress.

Perform Fiber Splicing

Use fusion splicing for permanent, low-loss connections (typically
