2. Measured at 1.5 dB below reflection peak for typical connector with UPC polish (reflectance < -37 dB multimode) using narrowest pulse
3. Measured at ± 0.5 dB beyond backscatter for typical connector with UPC polish (reflectance of < -37 dB multimode) using 40 ns pulse
4. Distance ranges for typical fiber loss. For typical fiber with backscatter coefficients of -67 dB at 850 nm and -74 dB at 1300 nm. Manual
5. SNR=1 method. Subtract 1.56 dB to compare to Telecordia 98 % method.
