The 𝛌 button allows you to select the wavelength of the transmitted light. The selected wavelength is shown in the centre of the LCD display.
The Mode button allows the selection of different laser light modulations. The following options can be selected:0 Hz (continuous), 270 Hz, 330 Hz, 1 kHz and 2 kHz. The selected modulation frequency is automatically detected by the KE8000 Optical Power Meter and the measured value is displayed correctly. The selected modulation is shown in the upper right corner of the display.
The KE8200 is an inexpensive and easy-to-use optical light source in pocket format for attenuation measurement during installation and maintenance of singlemode optical networks.
