Additionally, the PCVFL can be used as an
end-to-end visual fiber identifier, which is useful for locating fibers
terminated in poorly labeled or unlabeled fiber patch panels. A single switch is used to operate the
PCVFL, toggling the unit between OFF, CW (continuous wave), and Pulsed
modes
An example of PCVFL being used as a fault
locator:
Extreme caution must
be exercised when operating the PCVFL. Lasers such as the ones in the
PCVFL produce intense beams of laser light that are harmful to the eye.
Exposure to such energy can cause serious retina damage, and prolonged
exposure can cause blindness. TO ENSURE YOUR SAFETY: NEVER LOOK INTO A
LIGHT SOURCE OR THE END OF A FIBER THAT MAY BE ENERGIZED BY A
SOURCE!
