Fixed parameters block contains key information for interpreting the test data

Fields

date_time_stamp: u32

Datestamp - unix epoch seconds, 32-bit. Remember not to do any OTDR tests after 2038.

units_of_distance: &'a str

Units of distance - km, mt, ft, kf, mi, etc. Typically mt (in civilised nations)

actual_wavelength: i16

Actual wavelength used - normally the factory-calibrated wavelength in nm, or nominal wavelength

acquisition_offset: i32

Acquisition offset - this is the length of fibre from the OTDR port to the first data point in the DataPoints, in 100ps increments

acquisition_offset_distance: i32

As acquisition_offset, but as 10x units_of_distance

total_n_pulse_widths_used: i16

The total number of pulse widths used, if more than one pulse width’s results are stored in the file

pulse_widths_used: Vec<i16>

The list of pulse widths used, in nanoseconds

data_spacing: Vec<i32>

Data spacing, time taken to acquire 10,000 points in 100ps increments

n_data_points_for_pulse_widths_used: Vec<i32>

Number of points stored for each pulse width

group_index: i32

Group index - the refractive index of the fibre, default to 146800 if nothing supplied

backscatter_coefficient: i16

Backscatter coefficient -

number_of_averages: i32

Number of averages - the number of samples that were averaged to generate the result - may be used instead of averaging time

averaging_time: u16

Averaging time - may be supplied instead of number of averages - in seconds x 10

acquisition_range: i32

Acquisition range set by the tester to reach the end of the fibre - as with other distance measurements, 100ps increments

acquisition_range_distance: i32

Acquisition range in 10x distance units, as an alternate to acquisition_range

front_panel_offset: i32

Front panel offset is the time taken, in 100ps increments, between the front-end of the optical TRX and the front panel connector

noise_floor_level: u16

Noise floor level - the lowest power level for which 98% of the noise data lies below; 5-digit -dB value (e.g. 10200 = -10.2dB)

noise_floor_scale_factor: i16

Scale factor for the noise floor level - defaults to 1

power_offset_first_point: u16

Attenuation in dB*1000 applied by the instrument if done by the instrument

loss_threshold: u16

The threshold in dB*1000 for a loss-type event; default 00200

reflectance_threshold: u16

The threshold in -dB*1000 for reflectance events; default -55000

end_of_fibre_threshold: u16

The threshold in dB*1000 for the loss taken to detect the end of the fibre; default 03000

trace_type: &'a str

Trace type - identifies if this is a standard one-way trace, a bidirectional trace, reference trace, difference trace, or reversed trace

window_coordinate_1: i32

Window coordinate for the upper right window corner

window_coordinate_2: i32

Power coordinate for the upper right window corner

window_coordinate_3: i32

Window coordinate for the lower left window corner

window_coordinate_4: i32

Power coordinate for the lower left window corner
