WARNING: Fiber optic sources emit infrared light invisible to
the human eye that can damage the retina. Never look directly
into a source or into the end of a fiber energized by a source.
When working with raw fiber optic cable, be careful of fiber
ends or slivers that can puncture the skin and cause irritation.
1. Attach the anti-static strap to your wrist.
