PM TLD6000 series with a chip microcomputer control and the large-screen graphics LCD, it can provides precision measurement in the 0.65 to 1.65 μm wavelength ranges, from -70 dBm to +23 dBm range. It also can test the PM power to the light, light stability, insertion loss, optical transmittance, reflectance of light. This dynamic range makes OPM-XC powerful enough to match the optic fiber CATV systems, optic fiber communications networks deployment and test.
