ST3820 Optical Fiber Ldentifier with VFL

ST3820 Optical Fiber Identifier is an important tool for optical fiber network maintenance, which is used for nondestructive fiber identification work, can be detect in any location of both SM and MM fiber.
ST3820 combines the functions of optical fiber identifier and vfl. It can help operators fast find fiber in a mass, indicate signal directions in fiber, indicate Live or dark fiber, and detect 270Hz, 1kHz, 2kHz from laser source. The optical fiber identifier is powered by normal AA A batteries.

Product Features

1. Indicate the signal directions and power in fiber
2. Indicate the signal presence or absence(Live or dark fiber)
3. Efficiently identifies the traffic direction and frequency tone (270Hz, 1KHz, 2KHz) with audible warning
4. Displays the relative core power
5. Don’t need to replace adaptor
6. Lower power indication
7. Build in 10MW VFL function
