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.
The PCVFL ships standard with ST connectors, or for added flexibility, a 2.5mm universal fiber connector option is available.
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.
