Optical fiber power measurement using different transfer standards

A comparison of different transfer standard optical fiber power detectors is present. Traceable to cryogenic radiometer, these planar, focus-planar and trap detectors have different characteristics during the optical fiber power values transfer because of the different input angles or fiber connectors. For different types of fibers and fiber connectors, a new trap detector is capable for the optical fiber power measurement, which has very little sensitivity for a variety of input conditions. Comparison of fiber power measurement using a planar and a trap detector is present by employing a three-lens method. A good agreement between the two types of detectors shows the feasibility of fiber power transfer using planar detectors
