a. Laser in CW mode, at 25° C
b. Guaranteed value corresponding to the one-way difference (in dB) between the level of back-
diffusion extrapolated at the beginning of the fiber and the level containing 98% of noise, after
3 minutes of averaging, with the largest pulse width (according to IEC 61749 standard).
c. Typical value corresponding to the difference (in dB) between the level of back-diffusion
extrapolated at the beginning of the fiber and the RMS noise level, after 3 minutes of averag-
ing, with the largest pulse width.
d. EDZ measured at +/- 1.5 dB below the peak of a non-saturated reflecting event at shortest
pulse width.
e. ADZ measured at +/- 0.5 dB on the basis of a linear regression, using a - 40 dB type reflec-
tance, at shortest pulse width.
