1.The Specification describes the guaranteed performance with the typical PC type connector when measuring; not consider the uncertainty because the refractive index of the fiber.

2. The dynamic range is SNR =1 the maximum pulse width within averaging time of 3 minutes

3. Conditions for dead zone measurement: reflection strength beleow-45dB, Event Dead Zone with 10ns pulses width measurement, Attention Dead Zone 50ns pulse width measurement.

4. Not include the uncertainty due to refraction of the fiber.

5. The products with different specifications, sampling rate will be different
