ST3820 Built in VFL Optical Fiber Identifier, Dry Battery

Product Detail

ST3820 Optical fiber Identifier with built VFL function optical fiber tester


I. Overview

ST3820 is an handheld Optical Fiber Identifier which is designed for optical fiber installation and maintenance. It combines OFI with VFL into one tester. It can not only identify the optical fiber, but also used as the visual fault locator. The appearance is simple and small. It is easy to carry for the operator.

II. Main Functions

Support to detect optical signals without disrupting traffic; based on non-destructive technology

Indicate the signal direction in fiber

Detect a variety of optical tones, 270Hz, 1kHz and 2kHz

Suitable for 0.25mm, 0.9mm, 3.0mm fiber, and no need to replace the clamp block, more convenient than others

Build in visible fault locator 1mW or 10mW optional

Battery low indication

Powered by 2 units of 1.5V AA alkaline batteries
