Operating modes
1. Guaranteed, with laser at 10 µs, over entire temperature range
2. Typical value corresponding to the difference (in dB) between the level of back-diffusion extrapolated
at the beginning of fiber and the RMS noise level , after 3 min. of averaging, with 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 type FC/UPC (-55 dB)
at shortest pulsewidth.
5. Substract 3dB when used in modulation mode (270/330/1k/2k Hz)

3. EDZ measured at 1.5 dB below the peak of a non-saturated reflecting event at shortest pulsewidth.
4. Guaranteed up to 40 km, including Chromatic Dispersion of the Laser.
5. ADZ measured at +/- 0.5 dB on the basis of a linear regression from a reflectance type FC/UPC (-55
