Relative Distance Measurement

Set the zero cursor to the distance to be used as reference.

Use this function when dummy fiber is attached to the near end.

The zero cursor is set to a point from which the distance is measured and each process is performed with the zero cursor position as 0 km.

The marker and event positions are displayed as the relative distance from the 0 km position of the zero cursor.

At the Event Table screen, fault points are not displayed form 0 km to zero cursor position. The fault points from 0 km to the zero cursor position are not included in the fault point count.

At calculation of the Total Return Loss at the Event Table and Auto Zoom menus, when the zero cursor is set on the far-end side of the sampling start point, calculation is based on the zero cursor point, not the sampling start point.

When relative distance measurement is set, 'R-MEAS' is displayed on the waveform screen.

When setting relative distance measurement, the Horizontal Offset Setting screen is fetched when select the [Measurement]-[Horizontal Offset] command.

The following items are displayed at the Horizontal Offset Setting screen.

Fixed Function

The Fixed function is for fixing Event markers at operator-specified points.  Event data such as the splice loss, return loss, and total return loss can be calculated using the fixed Event table at each measurement.  The fixed contents of the table are:

1. Position of Event markers

2. Event comments

Data at the fixed Events are re-calculated automatically either when the threshold of the splice loss, return loss or fiber end is changed, or when the back-scatter level has changed.

The MW9076Series, MW9070A/BOTDR can only create fixed Event files when the Fixed function is ON.  The Fixed function mode of the MX907600A Emulation Software can only be set to ON when a fixed Event file is loaded.  When Auto Search is executed, the Fixed function is set to OFF.

This emulation software offers no procedure for installing the Fixed function;  if it is necessary to set the Fixed function to ON again, reload the file again.

When the Fixed function is ON, the status differs from the normal status as follows:

o When the Fixed function is ON, an exclamation mark (!) is prefixed to the head of events in the Event table exceeding the threshold value.

o When the Fixed function is ON, recalculation does not start the Event search.


Both Ends Measurement

Mixes a pair of traces measured at both ends of a fiber.

This measurement unites one waveform traced from one end of the fiber with the other waveform traced from the other end.  It permits splice loss to be measured precisely even when different cables are mixed.

Selecting Measurement Mode

Select the [Measurement]-[Measurement Mode...] command to select the Emulation from the File-Open mode..

Reading Waveforms

Select the [File]-[Open...] command to read the waveforms. Open the waveform files traced from one end and the other end.

It is not allowed to perform a both-end measurement for the waveform data that has been recorded with other than MW9076 Series OTDR and saved in the standard format , standard V2 format and print format.

When dummy fiber attached to fiber to be measured

Uniting Both Ends Waveforms

About CDM File
Chromatic Dispersion V2 format (with an extension cdm)

Chromatic Dispersion V2 format.

The file with an extension cdm, which is used in the MW9076 series at version 2.0 or later and in MX907600A at version 2.0 or later, has a merit that the file size is usually under one tenth of the one currently in use, but it also has the following restrictions.

The waveform is recorded in the range of the wider one, displayed in the screen or the fiber far end +.

 Hence, there is no problem when it is measured by the OTDR as usual.  However, the data of the target Fresnel reflection may not be recorded when the far end marker is set in the position which has no relation with the target Fresnel reflection of this software, and the displayed range of the screen is set to the position which has no relation with the target Fresnel reflection and saves it.  Please be careful.

That CDM file's size is changed by display range, distance of between nearest far end marker and farest one, pulse width.

Example:
   Searches for fibers with a splice loss of 0.4 dB or greater at a splice 5km among fibers measured under the same conditions.

1.	Start the MX907600A.
2.	Select the [Measurement Mode] command of [Measurement] menu.
3.	Select the [Multi Fiber Measurement Mode] from [Measurement Mode] menu in the displayed [Measurement Mode] dialog, and click the [OK] button.
4.	Read the objective files using the [Open] command of [File]menu.
5.	Select the [Splice & Return Loss] command of [Measurement] menu.  The Splice & Return Loss measurement screen appears.
6.	Set the six markers around the splice point as shown above.
7.	Since the waveforms are difficult to look, adjust the vertical-direction display position. First, select the * marker and click the right mouse button where the waveforms are displayed.   A pop-up menu appears. Select the 'Adjust' on this menu. Otherwise, select [Adjust] from [Measurement]menu. The waveforms scattered in the vertical direction are grouped at the marker position so that the splice loss at the splice point can be seen at a glance.
8.	Click the right side (red circle in the above figure) to Limit field to display the threshold setup dialog.
9.	Set the threshold, as below.  Since searching for fibers with a splice loss of 0.4 dB or greater, set the threshold to the following:    Splice Loss < 0.4 dB
10.	Click the GO/NO-GO switching button to select the display of GO or NO-GO file names in the GO/NO-GO result display list. When [image] is displayed in the button, NO-GO files are displayed.  When [image] is displayed in the button, GO files are displayed.  For displaying files that exceed the threshold, set [image] in the button.
11.	When the GO/NO-GO results display list is clicked, files having a splice loss of 0.4 dB or greater are sequentially displayed in ascending order. In this example,  012.dat   0.425  007.dat   0.480  009.dat   0.685  are displayed. The number displayed at the right side of each file name is the splice loss in dB unit.
12.	Select the required file from the displayed file names.  Since the file 009.dat has the largest splice loss in this example, select it.  The example is shown above.
13.	Print the searched result, as below:  Select the [Print] command of [File] menu . Then, the splice loss and GO/NO-GO judgment result for each of the  files are printed.

When the waveforms is shifted in the vertical direction and are difficult to look:
  Click the right mouse button in the waveform area, and select the 'Adjust' from the displayed pop-up menu.
  The vertical-direction display positions are adjusted at the selected marker position, and the waveforms become easier to look.

To "Select file" window

A lot of measured trace data can be printed in various formats. This function can output a lot of data measured from both ends of a fiber by the easy operation.

Select [File] - [Batch] - [Report Output] from the menu, then "Setup for operation" window appears.

Setup for operation

Setup for operation

At first select the One way or Both ends.

Next choose the number of wavelength used to measure the target fiber from "Operating number of wavelength".

When selected "Any", a selection of files at the next  "Select Files" window can be done independently of the wavelength. At this time forms of report are "Trace Summary Report" and "Event Table" of one way measurement only.

Then select the ID type from [The item used as ID].

Press [NEXT] button after setting up the all items. The next window "Select Files" appears.

Select Files

How to operate "Select Files".

Drive

Select the Drive where measured data are saved in PC. The folders in the selected drive are displayed.

If the data are saved in low-speed device such as FD, "copy them" to high-speed device such as HDD beforehand.

Folder

Select the folder where the data are saved, and the files are shown on the File list.

Path Mask

Setup the Path Mask and the object file is shown on the File list. Input characters to limit the file name displayed on the file list, then only the files which contain these characters are displayed (Default setup is *.dat).

File list

The files which are defined by "File" and "Pathmask" are displayed.

The available files by this "Report Output" function are shown.

The available files by this "Report Output" function are as follows.

The measured "Analysis (.dat)" style files by MW9070B after Ver.3.

The measured "Analysis (.dat)" style files by MW9076 series

The measured "Standard (.sor)" style files by MW9076 series.

The measured "Standard V.2 (.sor)" style files by MW9076 series.

Click the above items (name, updated data, etc) to sort the files in alphanumerical order. And click the above the items again to sort the files to reversed order.

Add the files to "Selected file list"

When selected "Both ends" on "Setup for operation"

The fiducial side which is measured from both side is express as A side and an opposite side is expressed as B side in this software.

The measured data from A side to B side are expressed A  B

The measured data from A side to B side are expressed B  A.

Select files

Select the data to output which are measured on A end from the file list. Next press "Add A �¨ B" or drag the data to the "Selected file list A �¨ B" on the left side of the window. Also put another data which are measured from B end of the same fiber to "Selected file list B �¨ A" or drag the data to the "Selected file list B �¨ A" on the rigtht side of the window in a same way. It is necessary to put the data of A �¨ B and B �¨ A measured for a fiber in the same line on "Selected file list".

When selected "One way" on the "Setup for operation"

Select the data to output and press "Add" or drag the data to "Selected file list".

Note: The files which are already included in the list cannot be added.

Add files

Select an objective file on "File list", then drag and drop it over the blank label on the last of the "Selected file list". When dropping the file on the file of "Selected file list", the file is overwritten at the place and the previous file is gone.

Insert files:

Select an objective file on "File list", then drag and drop it between the lines to insert in the dragged place.

Reference Fiber

When check the box " Apply all event information of reference fiber to all files" on the "Output Parameter" window, the event information of reference fiber is used for all the other files. Only the data measured with the same wavelength as a reference fiber can be added to "Selected file list". When adding files of different wavelength to "Selected file list", delete all files with "Delete All" button or change to the other "Selected file list" by clicking "Wavelength selection" button.

Wavelength selection button

Click one of the "Wavelength selection" buttons to change the wavelength of "Selected file list". When "Reference fiber" is set, the name on the button changes to wavelength of the reference fiber. When 1 wavelength or Any is chosen on "Setup for operation", the button does not appear on the window.

Press [Next] button after selecting files.

The warning message comes out and does not show the next window if number of the selected files in "A�¨B" and "B�¨A" list at "Selected file list" does not relate.

Other functions

Delete

After selecting files from "Selected file list", press "Delete" button to delete the selected files from the list. The saved files in the folder are not actually deleted even if this "Delete" button is clicked.

Delete All

Press "Delete All" button to delete all the files displayed on "Selected file list". It also clears "Reference fiber" at the same time. Any reference fiber isn't specified at that time.

Add

After selecting files from "File list", press "Add" button to overwrite the selected files to the desired place on "Selected file list".

Trace Plot

To show traces in a report, check the check box "Trace Plot" and select a number of traces to output on 1 page

Report output

Check the check box "Report Output" to output the measurement results in a report. Then select the type of report

Analyze Before Output

Check the check box "Analyze Before Output?" to execute re-autosearch for all the traces with specified thresholds. It is possible to set re-autosearch ON or OFF for every wavelength. And the traces are automatically analyzed when the files are the manual measurement traces, even if mark is not on the check box. Then this function uses the thresholds as saved in each file.

IOR

Check the check box of "IOR" and enter IOR value  to set for all traces. It is possible to set IOR and ON/OFF for each wavelength.

Apply all event information of reference fiber to all files

Check the check box and all traces are processed as what has an event in the same position as a reference fiber. This function doesn't work on Trace Summary Report. It is possible to set ON/OFF for each wavelength.
