A fiber optic reel should be used to carry the butterfly shape

A fiber optic reel should be used to safely transport and deploy butterfly-shaped optical cables, ensuring proper coiling, minimal bending, and protection from mechanical stress.

Understanding Butterfly Optical Cables

Butterfly optic cables, also called flat drop cables, have a flat, symmetrical cross-section resembling butterfly wings. They typically contain one or two single-mode fibers in the center, flanked by strength members made of steel wire or fiber-reinforced plastic, and encased in a durable outer jacket suitable for indoor or outdoor use . This design provides flexibility, tensile strength, and protection against bending, crushing, and environmental stress .

Importance of Using a Fiber Optic Reel

A fiber optic reel is essential for handling butterfly cables because it:

• Prevents excessive tension and sharp bends, which can damage the fibers or degrade signal quality .
• Facilitates organized deployment, allowing the cable to be unspooled smoothly during installation .
• Protects the cable from crushing or kinking during transport and storage .
• Can include features like braking mechanisms to control unwinding speed and reduce mechanical stress .

Best Practices for Reel Handling

1. Follow the winding direction marked on the reel to avoid twisting the cable .
2. Limit rolling distance to prevent tangling or damage, typically no more than 20 meters at a time .
3. Use lifting equipment such as forklifts or special steps when moving heavy reels .
4. Avoid stacking reels directly on top of each other without reinforcement to prevent crushing .
5. Maintain the minimum bending radius specified for the butterfly cable to prevent microbends or macrobends .
6. Inspect the cable before deployment for any damage, correct length, and proper specifications .
7. For long cable runs, if reversal is needed, use an “8” pattern to allow the cable to twist naturally without damage .

Deployment Considerations

• Indoor installations: Butterfly cables can be routed along walls, ceilings, or conduits, taking advantage of their flat design for tight spaces .
• Outdoor installations: Use pulleys for overhead runs, avoid friction with structures, and consider UV-resistant or water-blocking jackets .
• Splice boxes: Ensure the curvature radius inside the splice box is not less than 37.5 mm and leave sufficient fiber length for secure connections . Using a fiber optic reel correctly ensures that butterfly cables maintain their structural integrity, optical performance, and long-term reliability during both transport and installation .
