optical power meter vfl
The optical power meter VFL (Visual Fault Locator) is an essential dual-function testing instrument designed for fiber optic network installation and maintenance. This versatile device combines precise optical power measurement capabilities with visual fault location functionality in a single unit. The power meter component accurately measures optical signal strength across various wavelengths, typically ranging from 800 to 1700 nm, with high precision and reliability. The VFL feature emits a bright red laser light at 650nm, making it easy to identify fiber breaks, bends, and other physical impairments in optical cables. The device offers multiple measurement units including dBm, dB, and mW, with an impressive dynamic range that can measure power levels from +26 dBm to -70 dBm. Its user-friendly interface typically includes a clear LCD display, showing real-time measurements and testing results. The instrument is designed with both single-mode and multi-mode fiber compatibility, making it suitable for various applications in telecommunications, data centers, and fiber optic network installations. Advanced models often include data storage capabilities, USB connectivity for result transfer, and automatic wavelength recognition features.
