Fiber Optic Safety



True/False
Indicate whether the statement is true or false.
 

 1. 

You should never look directly at the end of a fiber without checking for optical power with a power meter because some fiber optic networks have high enough power to cause eye damage.
 

 2. 

A fiber optic inspection microscope can increase the danger of high powered light sources by focusing it in your eye.
 

 3. 

Dangerous light from fiber optic cables is bright and easily visible.
 

 4. 

It’s easy to see if light is present in a fiber optic cable, just take a digital picture of the end of the fiber with your cell phone or digital camera and look for bright spot on the end of the fiber.
