a. Laser, at 25° C and measured at 10 µs
b. 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.
