PCVFL (Precision
Coupled Visual Fault Locator)
PCVFL (Precision Coupled Visual Fault
Locator) is a light-weight, hand-held tool used to quickly troubleshoot
faults in the continuity of both single mode and multi-mode fibers,
especially at fiber launch points or in OTDR dead zones. A high intensity visible red laser beam is precision-coupled into a optical fiber; breaks and micro-bends in the
fiber deflect the red light into the fiber jacket, producing a red glow at
the point of the fault.

Typical battery life in CW mode is 15
hours, and the short 12.5% duty cycle in pulsed mode extends the battery
life to 120 hours of continuous use.
Unlike standard light pens, the PCVFL precision-coupled visual fault locator
(VFL) is optimized for fiber optics. An optical ball lens placed near the laser output focuses the red laser light for optimum coupling
into optical fibers (often most pen-style laser pointers do not have
this feature), and
special electronics prevent the red laser from burnout (a common problem with pen-style red laser pointers), increasing the life of the
VFL.
The PCVFL ships standard with a 2.5mm
universal connector port.
An example of PCVFL being
used as a fiber identifier up to 5 kilometers in a singlemode or multimode
fiber link.
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

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!
