Overview
The VT-42OFI-A is a handheld instrument combining optical fiber identification, an Optical Power Meter (OPM), and a Visual Fault Locator (VFL) for fiber network inspection, installation, and maintenance.
It supports 0.25/0.9/2.0/3.0 mm fiber diameters without changing chucks. An LED light and backlit display support convenient operation in low-light environments.
Feature
-
Three integrated functions: Fiber identification, optical power measurement, and visual fault location.
-
Automatic signal recognition: Supports CW, 270 Hz, 1 kHz, and 2 kHz.
-
Signal direction indication: Left and right LEDs indicate signal direction.
-
No chuck replacement required: Supports 0.25, 0.9, 2.0, and 3.0 mm fiber diameters.
-
10 mW VFL: Operates at 650 nm, with a testing distance of 5–8 km as specified in the datasheet.
-
Integrated OPM: Supports multiple standard wavelengths for optical power measurement.
-
Convenient field operation: Handheld design, two AA batteries, and an LED light.
