- Quick Setup Mode: Allows for fast configuration of wavelength, distance range, pulse width, and measurement duration.
- Parameters Set Mode: For professional technicians, this mode enables detailed adjustment of wavelength, distance range, pulse width, measurement mode, IOR, non-reflection threshold, end threshold, and other parameters for more accurate curve results.
4.2.1 Event Map
The Event Map visualizes fiber optic link inspections, presenting information like fiber length, connector type, fusion points, or breakpoints in an easy-to-understand graphical format. It supports saving, viewing, zooming, and moving curves for detailed analysis. Event Blind Zone is less than 1.6m, and Attenuation Blind Zone is less than 8m.
