3.2 OTDR Function

The OTDR (Optical Time Domain Reflectometer) function is used to characterize optical fibers, measure fiber length, and locate faults. To use the OTDR function, select "OTDR" from the main menu. Ensure the fiber is properly connected to the OTDR port. The device will display a trace of the fiber, showing events like splices, connectors, and breaks.

Watch the video below for a demonstration of the OTDR function:

3.3 Visual Fault Locator (VFL) Function

The VFL function emits a visible red laser light into the fiber, allowing for quick identification of breaks, bends, or poor connections over short distances. Select "VFL" from the main menu and connect the fiber to the VFL port. The red light will be visible at the fault location.

3.4 Optical Power Meter (OPM) Function

The OPM measures the optical power of a fiber optic signal. Select "OPM" from the main menu. The device supports 6 calibration wavelengths (850nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm) and has a measurement range of -50~+26dBm. Ensure the correct wavelength is selected for accurate readings.

Observe the OPM function demonstration:

3.5 Optical Light Source (OLS) Function

The OLS provides a stable light source for testing fiber optic cables, often used in conjunction with an OPM for attenuation measurements. Select "OLS" from the main menu. The light source offers optional 1550nm wavelength.

See the OLS function in operation:

3.6 Data Management

The device supports data saving in SOR format and allows for keyboard input to edit file names and line numbers. You can access saved data through the "File" menu. The USB data interface allows for data transmission to a computer.
