1. Guaranteed, with laser at 25°C measured at 10 µs.
2. Value corresponding to the difference (in dB) between the backscattered level extrapolated at the origin of the
fiber and the RMS noise level , after 3 minutes of averaging, with the largest pulsewidth.
3. EDZ measured at 1.5 dB below the peak of a non-saturated reflecting event at shortest pulsewidth.
4. ADZ measured at +/- 0.5 dB on the basis of a linear regression from a reflectance of type FC/PC (-55 dB for
Singlemode and -35dB for Multimode) at shortest pulsewidth.
5. After 20 minutes warm-up time

width.
3. EDZ measured at 1.5 dB below the peak of a non-saturated reflecting event at shortest pulsewidth.
