66 <4. Basic Software Operations> 58 The same chart configuration window can also be displayed by selecting View>Viewer Config>Viewer_1 Config from the menu bar.

67 <4. Basic Software Operations> Configuring Chart Display You can configure a chart display by selecting the Chart Setup tab in a chart configuration window. (1) Data Type Select the type of data to be displayed. Temperature: displays temperature data Signal Level: displays signal levels ST: displays Stokes signal levels. AS: displays anti-stokes signal levels. CFL: displays loss (Calculated Fiber Loss) values.

68 <4. Basic Software Operations> 60 TIP The DTSX series calculates temperature data from measured signal levels. The CFL waveform is obtained by eliminating the effect of temperature from Stokes signal levels. As the correction value for the fiber loss for Stokes light is fixed at 1.2 db/km, the CFL slopes downwards when fiber loss is significantly large, indicating a deteriorated optical fiber. However, the CFL result is only meaningful in single-ended measurement and does not indicate fiber loss in double-ended measurement where the measurement results of the forward and reverse directions are combined. Moreover, beware that the CFL is useful only as reference data but not for quantitative assessment of fiber loss. (2) Channel This setting is not editable. (3) Temperature Unit Select the unit for temperature data. Available options are Celsius [degc], Fahrenheit [degf] and Kelvin [K]. (4) Depth / Distance Select the distance type.

77 6. Calibration Function 6.1 Temperature Calibration <6. Calibration Function > 69 Temperature calibration can be carried out using the Calibration wizard. This software provides many features for calibration. By presenting these features in a timely and orderly manner, the wizard guides a user through the calibration process. Details on individual features are described from Section 6.3 onwards. The DTSX series measures temperature distribution in the longitudinal direction using an optical fiber as sensor. To get correct measurement, it is necessary to correctly set the parameters that reflect the characteristics of each fiber. This process is known as calibration. Calibration is broadly divided into connection point calibration and temperature calibration. The former involves configuration of the length and sections of the laid fiber, while the latter enables correct temperature measurement by each fiber. TIP Fiber characteristic parameters are grouped under Fiber Setting. For details, see Chapter 5, Control Function. Calibration Measurement Data To perform calibration requires measurement data obtained by performing measurement with the actual DTSX series connected to the actual optical fiber to be used in operation. The requirements for this so-called calibration measurement data are described below. There are two ways to get calibration measurement data, either by performing measurement using the DTSX series during calibration or by loading previous measurement data stored on a PC. In either case, the measurement data obtained must satisfy the condition described later. Condition for Sampling Resolution The sampling resolution is determined according to Distance Range of the Measurement Control settings. Distance Range Sampling Resolution 30 km or less 1 m 50 km 2 m If you choose to get measurement data by performing measurement using the DTSX series during calibration, the Sampling Resolution is automatically set according to the Distance Range setting as shown in the table above. If you choose to get measurement data by loading previous measurement data stored on a PC, the Sampling Resolution setting of the measurement data to be loaded must satisfy the condition shown in the table. Otherwise, the measurement data cannot be loaded.

78 Connection Point Calibration <6. Calibration Function > 70 Connection point calibration configures the length and sections of a laid optical fiber. For temperature calibration to set the fiber characteristic parameters of an optical fiber, the fiber length and its sections must be defined accurately. For this purpose, connection point calibration involves adjustment of the DTSX exit position, the fiber end position, and various fiber positions in between. Connection point calibration requires performing temperature measurement using the DTSX series. Names of various positions for connection point calibration No. Item Description DTSX Exit Position The position where light pulses exit from the DTSX series Switch Exit Position The position where light pulses exit from the optical switch (*1) Connection Point Position The positions of connection points of a laid optical fiber, which consists of multiple optical fibers joined together Fiber End Position The end position of the laid optical fiber. (*2) *1: This item requires calibration only if the DTSX series is installed with an optical switch. *2: For double-ended measurement, this item is the switch exit position of the far-end channel Optical fiber Various positions for single-ended measurement Near-end channel 2 Optical fiber Far-end channel Various positions for double-ended measurement

79 <6. Calibration Function > 71 Temperature Calibration Temperature calibration aims to make temperatures measured by the DTSX series the same as the actual temperatures around the actual optical fiber. Therefore, when performing measurement using the DTSX series to get calibration measurement data, it is necessary to get the actual temperature around the optical fiber too during measurement. The use of actual temperatures around the optical fiber as reference temperatures is described below. Conditions for reference temperatures Obtain the reference temperatures using a calibrated thermometer. Besides specifying the temperature of a reference temperature, you must also be able to specify its position. The number of reference temperatures required for temperature calibration depends on the measurement principle (single-ended measurement or double-ended measurement). For single-ended measurement, the number of reference temperatures required also depends on whether the calibration parameter (Loss or Wavenumber) value is known. The table below shows the number of reference temperatures required. Measurement principle Single-ended measurement Number of Known parameters reference temperatures None 3 (*1) (*2) Loss 2 (*1) Wavenumber 2 (*1) (*2) Double-ended measurement *1: At least two reference temperatures are at different temperatures *2: At least two reference temperatures are at different positions 2 (*1) You can get multiple reference temperatures using a thermometer by changing the temperature at the same location. This software allows data acquired from up to two measurements by the DTSX series to be used for temperature calibration. If the required number of reference temperatures cannot be acquired from one measurement by the DTSX series, consider whether the required number of reference temperatures can be acquired by changing the temperature and performing a second measurement. The table below shows the conditions for accurate calibration. Conditions for accurate calibration If you have to get two reference temperatures at different positions, make the positions as far apart as possible. If you have to get two reference temperatures at different temperatures, make the temperatures as different as possible. When getting a reference temperature, maintain a uniform reference temperature for a fiber distance of at least 10 m. The length of the uniform temperature section must be known.

114 <6. Calibration Function > Adjust Fiber End Point (for double-ended measurement only) In double-ended measurement, the measurement results for forward measurement and reverse measurement are combined. If the measurement position differs between the forward and reverse measurements, accurate temperature distribution cannot be obtained. It is therefore necessary to calibrate the measurement position. The measurement position can be calibrated by adjusting the fiber end position. The chart displays two temperature distribution waveforms with markers. A marker list is also displayed in the Calibration Wizard dialog. One of the two temperature distribution waveforms is a double-ended measurement waveform that combines the forward and reverse measurement waveforms; the other waveform is the forward measurement waveform, which is used as a reference for adjusting the fiber end point. TIP - If No Change has been selected for Calibration Type for Fiber Connection earlier, this Calibration Wizard page is not displayed, and existing settings are used.

115 <6. Calibration Function > Measurement position here refers to logical position. More details follow. - The two temperature distribution waveforms have the same Distance axis but separate Temperature axes. More details follow. - The chart display can be manipulated even when the Calibration Wizard dialog is displayed. The signal return direction differs between forward measurement and reverse measurement. Because of this characteristic, even if the physical measurement positions match, accurate temperature distribution cannot be obtained. As shown in the figure below, adjustment of logical measurement positions is necessary. Temperature Forward measurement Reverse measurement Double-ended measurement (before adjustment) Reverse measurement Adjustment Double-ended measurement (after adjustment) Display Item Temperature Forward measurement Reverse measurement Double-ended measurement (before adjustment) Reverse measurement (after adjustment) Double-ended measurement (after adjustment) Description Shows the actual temperature change. Shows the forward measurement result. Shows the reverse measurement result without measurement position adjustment. The signal return direction is opposite to that of forward measurement. Shows the double-ended measurement result that combines the reverse measurement without measurement position adjustment with the forward measurement. Shows the reverse measurement result after measurement position adjustment. Shows the double-ended measurement result that combines the reverse measurement after measurement position adjustment with the forward measurement.

116 <6. Calibration Function > 108 Measurement position is adjusted by adjusting the fiber end point. Specifically, by referring to the forward measurement waveform displayed in the chart, adjust the fiber end point on the double-ended measurement waveform so that the shape of the temperature change approaches the forward measurement waveform. Hereafter, we will refer to the forward measurement waveform as the reference waveform. If the measurement path has multiple sections, you can make use of the automatic adjustment function. TIP - If the measurement path has no temperature change point, adjustment will be difficult because there is no comparison point. - The double-ended measurement waveform and the reference waveform displayed in the chart do not show correct temperature as they have not been calibrated. Therefore, you should compare and adjust the shape of the temperature change point rather than its temperature value. We describe below the various parts and functions of the page. Channel number Marker description Marker position Marker interval Temperature Marker type Marker controls Display Item Channel number Type Description Position Temperature Space Marker controls Description Displays the number of the channel to be calibrated.

126 <6. Calibration Function > Adjust Double End Settings (for doubleended measurement only) For double-ended measurement, specify the Double End Settings. As measurement results of the forward and reverse measurement are combined in double-ended measurement, loss correction is not required but measurement accuracy might be improved with appropriate double-ended settings as described here. Specify the fiber near-end and far-end positions and the system will automatically determine the total differential loss between the Stokes and anti-stokes signals over the full fiber length. Using this value for temperature correction will improve measurement accuracy. The temperature distribution waveform is displayed in the chart along with markers. Double End Setting related parameters are also displayed in the Calibration Wizard dialog.

127 <6. Calibration Function > 119 TIP - If single-ended measurement is specified for Principle earlier, this page is not displayed. - If No Change has been selected for Calibration Type for Fiber Connection earlier, this Wizard page is not displayed, and existing settings are used. - The marker list display in the Calibration Wizard dialog window is interlocked with the marker display in the chart. - The chart display shows a Distance-Temperature chart. - The chart display can be manipulated even when the Calibration Wizard dialog is displayed.

162 6.20 Measurement Control Settings <6. Calibration Function > 154 Measurement Control settings You can specify measurement control settings required for actual measurement after calibration ends. The table below describes each parameter. Item Sampling Resolution Averaging Fiber Failure Detection Calculation Range Increased Loss Detection Description This parameter determines the sampling resolution for A/D conversion. If the specified sampling resolution is shorter than 1 m, multi-sampling is performed by shifting the sampling time. This parameter specifies the number of times measurement is to be repeated for averaging purpose. Averaging can be used to improve the signal-noise ratio when the Raman scatter signal level is very weak, If Measurement Time is selected, the specified measurement time is used to determine the number of measurements to be used for averaging. Select the ON checkbox to enable fiber failure detection. If enabled, specify a threshold level for fiber failure detection. When enabled, fiber failure detection outputs a warning if the loss for a certain distance exceeds the Threshold Level and the signal level falls below a certain level. However, no fiber failure will be reported near and beyond the specified Fiber-End even if the loss is large. Fiber failure is detectable from 0 [m] to [Fiber End] - X [m], where X varies with [Fiber End] (length). <Reference> 0~10 km : X=10[m], 10~20km : X=20[m], 20~30km : X=30[m], 30~40km : X=40[m], 40~50km : X=50[m] This parameter determines the calibration range. Available options are Total Length, All Data or Range Setting. If you have selected Range Setting, specify the Start and End positions. This parameter relates to increased loss detection. Select the ON checkbox to enable increased loss detection. When enabled, increased loss detection outputs a warning if the CFL level near the fiber far-end (Fiber End - X[m]) falls below the Threshold Level,, where X varies with [Fiber End] (length). <Reference> 0~10 km : X=10[m], 10~20km : X=20[m], 20~30km : X=30[m], 30~40km : X=40[m], 40~50km : X=50[m]

163 <6. Calibration Function > 155 IMPORTANT - Actual measurement time might differ from the measurement time setting, and might fluctuate. The difference between actual measurement time and the measurement time setting increases when DTAP3000 connection, alarm detection, sectional data generation, data conversion, data transfer and other functions are used. - The Measurement Time setting allows any value from 1 (second) to be specified but a value from 10 (seconds) onwards should be specified as the shortest practical measurement time is around 10 seconds. - To ensure accurate measurement results, select a distance range that is definitely longer than the fiber to be measured. - The fiber failure location reported by fiber failure detection might be inaccurate depending on the specified measurement condition (Measurement Time, Averaging Times). To ensure accurate detection, we recommended specifying a sufficiently long measurement time (or sufficiently large value for Averaging Times). - Similarly to fiber failure detection, to ensure accurate increased loss detection, we recommended specifying a sufficiently long measurement time (or sufficiently large value for Averaging Times). SEE ALSO These parameters can also be set from the Measurement Control tab and Fiber Setting tab of Channel Setting of the control function. For details, see Chapter 5, Control Function.
