How to Cut & Connect Laser Wire

Laser Wire is designed to be cut to length and reconnected, but proper technique is critical to ensure even brightness, strong light output, and long-term reliability. Unlike EL Wire, Laser Wire uses a fiber optic core illuminated by a precision light source, which means clean cuts, accurate alignment, and correct connector use matter.

This guide walks through the recommended process for cutting and connecting Laser Wire safely and effectively. The video above demonstrates the full procedure step by step, while the written guide below provides key reminders and best practices.

Tools You’ll Need

• Sharp flush cutters or precision blade
• Approved Laser Wire connector
• Light source module (Capsule or DMX RGB)
• Optional polishing pad or fine-grit sanding surface

Step-by-Step Overview

1. Measure and Cut

Measure your desired length carefully before cutting. Make a clean, straight cut to avoid crushing or deforming the fiber core. Jagged cuts or angled ends can reduce brightness and cause uneven illumination.

2. Prepare the Fiber End

Ensure the fiber end is clean and free of debris. If needed, lightly polish the cut surface so the core is flat and centered. A smooth, perpendicular surface improves light coupling into the fiber.

3. Insert into Connector

Fully seat the fiber into the connector so the core aligns directly with the light source. Partial insertion or misalignment will result in light loss.

4. Secure the Connection

Tighten or lock the connector according to its design. Avoid over-tightening, which can damage the fiber.

5. Test Before Final Installation

Power the module and confirm even illumination before permanently installing the wire.

Common Mistakes to Avoid

• Crushing the fiber during cutting
• Angled or uneven cuts
• Using non-approved connectors
• Skipping alignment and testing
