*1 Based on 2^16 average cycles.
*2 Based on average fiber loss of 0.3 dB/km using single mode fiber.
*3 Based on the measurement of strain-free, UV-coated fiber.
*4 Based on the measurement with strain-free, UV-coated fiber and in constant temperature environment.
*5 Maximum standard deviation of measurement value in 5 consecutive measurements for 100 consecutive points.
*6 The setting of 50m range, 2^8 count settings, 41 scanning steps in batch processing mode. (PPP-BOTDA only).
*7 The settings of 50m range, 2^8 count settings, 1 scanning step in batch processing mode.
*1-*5 are all based on a frequency scan step of 5 MHz with Pre-Pump Adjustment on.
