Notes & Cautions:
1. It is strictly prohibited to direct the laser at the human eye.
2. Please take precautions to avoid static electricity releasing.
3. Output power is measured by multi-mode fiber at 23°C±3°C.
4. Detecting range and working hours may vary depending on fiber quality and battery brand.
Frequently Asked Questions
What is the maximum distance the VFL-08 series can cover?
Depending on the specific model, the dynamic distance ranges from 2-5km (1mW model) up to 22-30km (50mW model).
Does this visual fault locator support multi-mode fibers?
Yes, the VFL-08 series is designed for measurement in both single-mode and multi-mode optical fibers.
Is the ceramic tube replaceable?
Yes, the ceramic tube is designed to be user-replaceable, which helps in extending the service life of the device.
What type of batteries are required?
The device operates on two standard alkaline batteries (AA or AAA depending on the specific series configuration, standardly AA*2 as listed in specs).
What are the available laser modes?
It supports both Continuous Wave (CW) for steady illumination and Pulsed mode for easier identification in high ambient light environments.
What connector size does it use?
It features a 2.5mm universal connector, making it compatible with most standard fiber optic interfaces.
