1. Laser, at 25° C and measured at 10 µs
2. Typical value corresponding to the one-way difference (in dB) between the extrapolated backscattering
level at the beginning of the fiber and the RMS (SNR = 1) noise level, after 3 minutes averaging and
high dynamic resolution, using the largest pulse width.
3. EDZ measured at ± 1.5 dB below the peak of a unsaturated reflective event using the shortest pulse
width.
4. ADZ measured at ± 0.5 dB from the linear regression, using a FC/UPC- type reflectance, at shortest
pulse width.
5. At 1650 nm
6. At 1550 nm
