WebReflectance is defined by the amount of light reflected compared to the power of the light being transmitted down the fiber. Thus a 1% reflectance is -20 dB, which is about what you get from a flat polished air gap connection, and 1 part per million would be -60 dB, typical of an APC connector. http://www.hamuniverse.com/swr.html

Return loss - Wikipedia

WebReturn loss. In telecommunications, return loss is a measure in relative terms of the power of the signal reflected by a discontinuity in a transmission line or optical fiber. This discontinuity can be caused by a mismatch between the termination or load connected to the line and the characteristic impedance of the line.
