Optical Multi-Meter Operates in Three Modes

This optical multi-meter, model 2498A, covers 0.85µm, 1.30µm, 1.31µm and 1.55µm wavelengths for optical loss measurement within a measurement range of 3dBm to -70dBm or 20dBm to -50dBm. It offers CW mode light signals with a measurement resolution of 0.1dBm to 1dB in W display mode or 0.01 to 0.1dB in REL display mode. The handheld optical multi-meter provides a wavelength calibration function at four wavelengths including 850nm, 1300nm, 1310nm and 1550nm. The measurement range can be specified and set to be on and off. What’s more, the deviation of optical power sensor is compensated for automatically.
