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 multimode fibres, especially at fibre launch points or in OTDR dead zones.
A high-intensity visible red laser beam is precision-coupled into an optical fibre; breaks and micro-bends in the fibre deflect the red light into the fibre jacket, producing a red glow at the point of the fault.
Additionally, the PCVFL can be used as an end-to-end visual fibre identifier, which is useful for locating fibres terminated in poorly labeled or unlabeled fibre patch panels.
A single switch is used to operate the PCVFL, toggling the unit between OFF, CW (continuous wave), and Pulsed modes.
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.
The PCVFL ships standard with a 2.5mm universal connector port, which allows for connection to ST, SC, and FC connectors.


High-intensity visible laser allows for visible fault location of breaks and microbends in both single-mode and multimode fibres

Both Continuous Wave mode and Pulsed mode allow for easy fibre identification
