Connector-induced offsets in optical fiber power meters

We discuss issues related to calibration of optical fiber power meters. The power readings may vary when using various types of fiber connectors, or even the same type of connectors made by different vendors. We study the connector effects by calibrating four types of optical fiber power meters using six different fiber connectors from four vendors at three wavelengths. We found variations of as much as 12 % due to the different reflection properties of the detector windows, connectors, and detectors. We also compared connector measurement results with the data obtained using open beams.
