Cable crimping quality check

This function is used to check the quality of cable ends crimping for proper connection of conductors to pins.

Plug one end of the testing cable to the QC/CONT port (5) on the transmitter and leave the other cable end disconnected.

Select QC TEST (Quality check of cable connectors) in the main menu and press the OK button (7).

Possible outcomes are shown below:

Optical power meter function

This function is used to test the optical power and the attenuation value of the optical signal to check fiber cables.

Connect one end of the fiber cable end to the fiber optic connector (1); connect the other fiber cable end to corresponding connector

of the external optical light source (external device).

Turn on the external optical light source (external device).

Select OPM (Optical power meter) in the main menu, and press the OK button (7) to enter the optical power meter mode.

4. Select the unit of measurement (dBm, dB, µW, mW, nW).

Select a wavelength value (850nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm).

Set the optical power value by changing the user settings (User value settings).

Select REF (Reference value), then press and hold the OK button (7) to save the current optical power value in the first blue line.

The measurement unit will be switched to dB and cannot be changed to other units.

If you do not save the value in REF, the first blue line will display normal optical power characteristics, but the second blue line

of the user settings will not contain any value.

Visual fault locator

The VFL function is used to test fiber cables.

Plug one end of a fiber cable to the VFL connector (3) on the transmitter and leave the other end of the cable disconnected.

Select VFL (Visual fault locator) in the main menu and press the OK button (7).

You can select three modes: Fast flash 2 Hz, Fast flash 1 Hz, and Light.

In case of no breakage in the cable, the red LED on the end of the cable will light on. If the fiber cable is damaged, the damaged part of

the cable will glow red.
