1. Auto OTDR
There is no need to do complicated settings, one button operation.
2. Expert OTDR
It provides professional measurement and displays curve, list and map simultaneously.
3. Event Map
Event Map is similar to EXFO’s iOLM function, which can display events in user-friendly icons.
4. Optical Power Meter (OPM)
5. Visual Fault Locator (VFL)
Visual Fault Locator uses red laser of 650nm to locate broken fiber point and test fiber continuity.
6. Optical Light Source (Laser Source)
7. RJ45 Tracker
It can trace and locate the RJ45 network cable.
8. RJ45 Sequene
It can check wire map of RJ45 cable.
9. RJ45 Length
It can measure the length of RJ45 cable.
10. Laser Distance Meters
It includes 12 functions: Single, Continuous, Addition, Subtraction, Angle, Hypotenuse, Height (1), Height (2), Triangle Area, Rectangle Area, Volume, and Speed.
11. Optical Loss Test
Optical Light Source (OLS) can run in the background. Open OLS first and then open OPM to test insertion loss.
When OLS and OPM are used together, TWINS function can be opened to identify the wavelength and frequency of the tester laser source.
