The OLS-100 is an Optical Light Source that can be used in conjunction with our OPM-300 Optical Power Meter to test installed fiber cabling for attenuation loss over medium to long distances. The OLS-100 can provide 1 to 4 wavelength outputs according to the specific requirements including 650nm visible red source, 1310/1550nm wavelength for single mode fiber and 850/1300nm wavelength for multimode fiber. Together with any optical power meter, it acts as a perfect solution for confirming or troubleshooting an optical fiber network.
