• VFL power: 10mW at 650 nm
• Connector compatibility: FC, SC, ST
• Display: Color LCD
• Power supply: 3.7V 1500mA lithium battery
• Operating temperature: -20°C to 50°C
• Dimensions: 139 x 84 x 29 mm

How to use

To begin, power on the device and select the desired mode between the Optical Power Meter or the Visual Fault Locator. For power measurements, connect the fiber cable to the appropriate port and select the corresponding wavelength on the display to view the signal strength in dBm or mW. When using the VFL, connect the fiber to the VFL output port and choose between steady or flashing light modes to visually trace the fiber path and locate faults. Ensure all connectors are clean before insertion to maintain measurement accuracy.

What to consider before purchase

• Verify that your fiber network uses FC, SC, or ST connectors.
• Ensure the required testing wavelengths match the device specifications.
• Consider the need for additional cleaning tools for fiber end-faces.

Usage recommendations: Always inspect and clean fiber optic connectors with specialized cleaning supplies before connecting them to the device to prevent damage to the internal sensors and ensure accurate readings.
