Bundling Method for Optical Fiber Cables

Optical fiber cables should be bundled carefully using fiber binding tape, arranged neatly, and handled gently to prevent damage and signal loss.

Preparation and Handling

Before bundling, ensure that optical fibers are not bent excessively or pulled forcefully, as this can damage the fibers and degrade signal quality. If using corrugated pipes or cable trays, cut them to the desired length and wrap adhesive tape around sharp ends to protect the fibers. Keep optical fibers separate from other cables to avoid interference and mechanical stress, and route them along cabinet posts or trays as needed for organized installation.

Arranging Fibers

Arrange the fibers into a tidy bundle without crossover. For larger installations, divide cables into groups and place them evenly in cable trays or troughs. This ensures that fibers are accessible and reduces the risk of tangling or damage during maintenance.

For fiber bundles used in applications like imaging or spectroscopy, fibers can be arranged in hexagonal, circular, or rectangular patterns to maximize packing density and mechanical robustness. Bundling with Fiber Binding TapeUse optical fiber binding tape, typically 12. 5 mm wide with a hook side and a mat side.

The mat side should contact the fibers, while the hook side wraps around to secure the bundle. Steps include: Cut a piece of binding tape appropriate for the bundle size. Hold the fiber bundle with one hand and press one end of the tape onto the bundle.

Stretch the tape with the other hand and wrap it around the bundle until the mat side adheres snugly to the hook side. Ensure the fibers are bundled with appropriate force—tight enough to hold them together but not so tight as to damage the fibers.

Additional Tips

Keep the bundle flexible if needed for routing through trays or conduits. Label bundles clearly for easy identification. For specialized fiber bundles, such as those used in bifurcated or fan-out configurations, connectors may be added to facilitate connections to instruments or devices.

Avoid mixing different types of fibers in a single bundle unless designed for that purpose, as differences in numerical aperture or core size can affect performance. By following these steps, optical fiber cables can be safely and efficiently bundled, ensuring organized installation, minimal signal loss, and easier maintenance.
