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.
Optical Multi-Meter Operates in Three Modes
GAO Fiber Optics, a leading supplier of fiber optic equipment, launched its upgraded, highly accurateoptical multi-meter .which can act as an optical power meter and a stable light source or be used as a loss measurement system. It is intended to measure optical loss and check the performance of optical parts. The optical meter is specifically designed for single mode fiber measurement. It has a high definition backlit LCD screen and an AC-DC adaptor, a rechargeable Ni-Cd battery and dry cells as power sources for selection. A compact size and light weight design makes it ideally suited for fieldwork.
