Product Description
Fiber optic light source


DT-OLS-111  fiber laser source Is a handheld optical light source, newly released in 2007. It can provide 1 to 6 wavelengths output to satisfy specific  requirements including the 650nm visible light source and the 1310/1550nm wavelengths for single mode fiber or the 850/1300nm wavelengths for multimode fiber, as well as other wavelengths according to customer's needs. Together with the DT-OPM-211 optical power meter, it is a perfect solution for fiber optic network applications.


Provides1~6 wavelengths output which can be optional according to customers' needs
CW,2Hz modulation output at 650nm, and CW, 270Hz,1KHz,2KHz modulation output atother wavelengths.
