204 E6000C Mini-OTDR Users Guide, E0302
Output power stability (CW)
Peak-to-peak variation of the output power in CW mode.
Conditions: Jumper fiber attached to the OTDR port;
output power stability measured with an optical power
meter at the end of the jumper fiber. Warmup-time and
observation period as specified. Power meter averaging
time 100 ms.
Reflectance accuracy
For the specified reflectance range, the maximum
difference between the measured reflectance of a feature
on the fiber and actual (true) reflectance, in dB.
Conditions:
signal-to-noise ratio larger than specified
value, at specified instrument settings,
backscatter
coefficient correctly set for the specific fiber used.
Sample spacing
The distance between consecutive data points.
Signal-to-noise ratio (SNR)
The difference between the actual backscatter level and
the
noise level (98%) expressed in dB.
