How far can a VFL go?
VFL distance and eye safety
| VFL range under ideal conditions | Power level connected | “Connector end view” continuity |
|---|---|---|
| KI9808 | +7 dBm | 10.7 Km |
| Class 2M Legal Limit | +10 dBm | 11.2 Km |
| Illegal VFL “20Km” | +20 mW / 13 dBm | 11.7 Km |
| Illegal VFL “30Km” | +30 mW / 14.8 dBm | 12 Km |
What is a VFL tester?
The laser-powered VisiFault Visual Fault Locator is a cable continuity tester that locates fibers, verifies cable continuity and polarity. This cable continuity tester helps find breaks in cables, connectors and splices. This visual fault locator has a long battery life for hours of use.
What does a Visual Fault Locator do?
A visual fault identifier or visual fault locator (VFI / VFL) is a visible red laser designed to inject visible light energy into a fiber. Sharp bends, breaks, faulty connectors and other faults will “leak” red light allowing technicians to visually spot the defects.
How do you use Fluke Visual Fault Locator?
How to use the Visual Fault Locator
- Clean and inspect the connectors on the patch cord, if used, and the fiber to be tested.
- Connect the fiber directly to the VFL port or use the patch cord to connect to the port.
- Use the VFL button to turn on the visual fault locator (see picture below).
What is the Best Visual Fault Locator?

How do you use VFL fiber?
The steps to use a VFL are provided as following: Step One: remove the plastic connector covers from both ends of the test fiber cable. Step Two: connect the fiber optic visual fault locator one end of the fiber. Press the tester button and observe that light emanates from the other end of the fiber.
What precautions are observed when using Visual Fault Locator?
Precautions of Using Visual Fault Locators
- Never look into the path of the Laser Beam and never look into the end of a fiber.
- Keep away from water, dust, static electricity, and environments of extreme temperature.
- Remove the batteries for prolonged periods of storage.
What is power meter in fiber optic?
An optical power meter (OPM) is a device used to measure the power in an optical signal. The term usually refers to a device for testing average power in fiber optic systems. The sensor primarily consists of a photodiode selected for the appropriate range of wavelengths and power levels.
What is fault pen?
In the UK we call this a PEN conductor fault. It’s called a PEN conductor when it’s used as a combined Protective Earth & Neutral, as in a TN-C-S earthing arrangement. This risks melting and subsequently breaking the conductor, leading to: 2) The exposed metalwork in your house becomes live.
