Installation of Plastic Reels for Indoor Optical Cables

Proper installation of indoor optical cables from plastic reels requires careful handling, correct reel orientation, and adherence to bend radius and tension limits to prevent damage and ensure safety.

Safety and Preparation

Before beginning installation, ensure all personnel are familiar with OSHA regulations, the National Electric Safety Code (NESC), and local building codes. Set up barricades, ladders, and warning signs to minimize hazards, and inspect all equipment such as cable stands and ladders for defects before use. Avoid stepping on cables or equipment, and keep hands free when ascending or descending ladders to prevent accidents.

Reel Handling and Storage

Orientation: Store reels vertically on their flanges, end-to-end in rows, and chock them to prevent rolling. Reels should rest edge-to-edge with adjacent reels to avoid cable damage. Inspection: Check reels for protrusions, broken flanges, or nails that could damage the cable during unrolling.

Unattended Reels: Protect reeled cable from mishaps whenever unattended, as damage to pre-connectorized sections may require replacement of the entire section. Lifting: Use forklifts or reel movers with forks perpendicular to the reel. Never drop reels, as this can compromise structural integrity and cause de-reeling issues.

Installation Techniques

Tension and Bend Radius: Avoid exceeding the cable's maximum tension and minimum bend radius. Do not bend cables more than 90 degrees during installation, and maintain the long-term bend radius after installation.

Figure-

Eight Method: For long lengths, use a figure-eight configuration to prevent kinking or twisting. Loops should be approximately 5–8 feet in length, with cardboard shims at crossovers to relieve pressure. Pulling: Establish clear communication between pull, feed, and monitoring locations.

Use cable lubricants if necessary, and clean up spills to prevent slipping.

Specialized Packaging Solutions

For small indoor installations, Reel in a Box solutions provide compact, pre-packaged reels that simplify deployment. These are ideal for collocation data centers, wireless projects, and distributed antenna systems. ActiFi® Composite Cables integrate fiber and linear-laid copper, reducing the need for separate power and fiber cables, saving labor, duct space, and installation time.

Standards and Compliance

Follow ITU-T L. 103 for indoor optical fiber cable characteristics, construction, and testing. Ensure that the cable meets the required specifications for the intended environment, and coordinate with the manufacturer for detailed test conditions.

Key Takeaways

Always prioritize safety and regulatory compliance. Inspect and store reels properly to prevent damage. Maintain tension limits and bend radius during installation.

Use figure-eight coiling for long cable runs and specialized packaging for small indoor projects. Adhere to ITU-T standards and manufacturer guidelines for optimal performance. By following these practices, indoor optical cable installations from plastic reels can be performed efficiently, safely, and with minimal risk of cable damage.
