About Application Function

1.1 TLS Application This TLS application function measures the insertion loss (IL) of the performance of a passive component used for the optical network, such as WDM network with this unit to be mounted on the AQ2201/AQ2202 Frame Controller combined with OPM module. Measurement result display, analysis, and data save functions of each measurement are provided. The application using the TLS module provides two measurement functions as described below.

Swept: By synchronizing with the OPM module, an optimal sweep type is selected from three sweep types to measure the IL. By setting up a threshold level, the OK or NG judgement of the analysis item can be performed easily.

Manual: The wavelength sensitivity correction value of the OPM module can be changed automatically while linking with the wavelength set using the TLS module. Use of this function makes it possible to perform the measurement with the wavelength display linked with the measurement result of the OPM module.

Pressing the "APPLI" key on the frame controller will start up this TLS application function.

Swept Measurement

2.4 Operating the Wavelength Calibration and ZERO-SET

When operating this unit, you must calibrate the wavelength every time the laser output is turned ON. This section describes how to calibrate the wavelength. The Swept measurement cannot be started unless the wavelength calibration (WL Cal) is performed. Therefore, you must always calibrate the wavelength before staring the measurement.

Operating Procedures Note When canceling the operation during execution of the wavelength

calibration, the wavelength calibration, which has been performed until that time, becomes invalid. Therefore, before starting the operation, perform the wavelength calibration again to complete it.

This indication is shown if “WL Cal” is not completed. When “WL Cal” is completed, this indication disappears.

Press the <Zero> button to perform ZERO-SET of the OPM module. For details about ZERO-SET, see Chapter 3 in the User’s Manual for AQ2201 Frame Controller.

Press the <WL Cal> button to start the wavelength calibration. The execution screen appears while the wavelength calibration is running. The execution screen will disappear when the wavelength calibration is completed. Therefore, you need to wait until the execution screen disappears. For details about wavelength calibration, see Chapter 5 in the User’s Manual for AQ2200-136 TLS Module.

2.5 Setting the Sweep Conditions This section describes how to set up the sweep wavelength parameters, such as the sweep start wavelength, stop wavelength, and interval.

Setting the Sweep Area, Sweep Mode, Line Width, and Power Operating Procedures

Press the <TLS PRMTR> button. Select a sweep item on the popup screen to set it. For details about sweep, see the following Chapters in the “AQ2200-136 TLS Module User’s Manual” . • Start, WL, Stop WL, StepWL, Sweep Mode: Chapters 9 and 10 • Power: Chapter 8 • Linewidth: Chapter 7 • WLMC Settle: Chapter 12

Explanation Appropriate sweep conditions are used corresponding to the applications shown below.

Overall wavelength needs to be measured. : StartWL/StopWL/StepWL One wavelength and its surrounding need to be measured. :

CenterWL/Span/Samples Measurement needs to be performed by increasing the measurement dynamic range. : Select “Step” for SweepMode setup.

Measurement results need to be known early. : Select “Continuous” for SweepMode setup. Note A sweep step of 0.001nm or less cannot be set.

20,000 or more measurement points cannot be set. Since the sweep wavelength range is determined by the sweep span and the number of measurement points, make the setting so that the wavelength range you want to measure is satisfied.

example: When the sweep span is set at “0.001nm” and the number of measurement points is set at “20000”, the sweep wavelength range becomes as shown below. 0.001nm × 20000 = 20nm

2.7 Starting the Reference Measurement Before starting the Swept measurement, you must always perform the reference measurement. Since the output characteristics of the TLS module cannot output the constant level to the wavelength axis, it is absolutely necessary to perform the reference measurement before measuring the device. This section describes how to operate the reference measurement.


When pressing the <Ref Meas> button, the "Ref Measurement" popup screen will appear, prompting you to check the execution. To start the reference measurement, press the <OK> button.

The progress bar showing the progress status is shown during measurement. Pressing the <Stop> button will abort the measurement. When the measurement is completed successfully, the "NO REF" indication will disappear. Note The reference measurement cannot be started unless the

wavelength calibration (WL Cal) is completed.

Explanation The following Table shows Ref valid/invalid when each parameter setting is changed.

Parameter Settings Valid, Invalid, Conditional

Item Ref Valid/Invalid Remarks Start WL Valid when the value is within the specified range of “Ref”.Stop WL Valid when the value is within the specified range of “Ref”.Step WL Valid when the value is within the specified range of “Ref”.Center WL Valid when the value is within the specified range of “Ref”.Span Valid when the value is within the specified range of “Ref”.Data Points Valid when the value is within the specified range of “Ref”.Sweep Mode Power Linewidth Range Mode WLMC Settle Average Sweep Cycles WL Cal Re-execution of WL Cal is invalid.

Module Settings

When using multiple OPM modules, the reference measurement data is valid even though any module is unmounted after completion of the reference measurement. (When at least one OPM module remains, which has been set during reference measurement, the reference measurement data is valid.)

However, if a new OPM module is mounted after completion of the reference measurement, the reference measurement data becomes invalid. At this time, you must perform the reference measurement again. Even though the OPM module is unmounted, which has been measured actually with "ALL OPM" during reference measurement, the reference measurement data is valid.

2.7 Starting the Reference Measurement

2.8 Starting the Measurement Before starting the Swept measurement, it is absolutely necessary to complete the reference measurement. If the reference measurement is not performed or if the reference measurement is disabled, the Swept measurement cannot be started on the screen. Therefore, you must check that the reference measurement is completed and the "NO REF" indication disappears. The measurement can be started from any of the following screens.

Operating Procedures When the reference measurement becomes valid, the indication of the <Meas> button is changed from the dimmed display to the normal display. In this case, when pressing this <Meas> button, the Swept measurement screen is started up. On the Swept measurement screen, you can start the measurement, the graph screen, and/or the analysis screen. If there is no Swept measurement data, "NO DATA" is shown. Additionally, the screen is transited to the Swept measurement screen even when the reference measurement is completed successfully.

When the indication is dimmed, this shows that the reference measurement is not completed.

The popup screen showing the confirmation message appears. After checking the message, press the <OK> button. The measurement is then started.

When a TLS module is selected, the color of the check box on the left is changed from white to green. On the contrary, when an OPM module is selected, the color of this check box is changed from white to black.

An optimal OPM module can be selected from two types, that is, AQ2200-211 and AQ2200-231. If one TLS module and one OPM module are not selected, the next screen is not displayed even though the <OK> function button or [ENTER] key is pressed.

[Completion of Operation]

Explanation The wavelength correction value of the OPM is changed while linking with the wavelength setting of the TLS module. This function is convenient for the system, in which multiple OPM modules are mounted on the frame controller having three or more slots. Note Since the AQ2201 Frame Controller is a type of 3-slot model, select all

modules to change the color of the check box to green (black for AQ2200-211 and AQ2200-231).

When checking on relevant check box, the dimmed <OK> function button is changed to the normal button display. At this time, when pressing the <OK> button or [ENTER] key, the main screen of the Manual function will appear.

3.4 Operating the Wavelength Calibration and ZERO-SET

When operating this unit, you must calibrate the wavelength every time the laser output is turned ON. This section describes how to calibrate the wavelength.

Operating Procedures Note When canceling the operation during execution of the wavelength

calibration, the wavelength calibration, which has been performed until that time, becomes invalid. Therefore, before starting the operation, perform the wavelength calibration again to complete it.

This indication is shown if “WL Cal” is not completed. When “WL Cal” is completed, this indication disappears.

Press the <Zero> button to perform ZERO-SET. For details about ZERO-SET, see Chapter 3 in the User’s Manual for AQ2201/AQ2202 Frame Controller.

Press the <WL Cal> button to start the wavelength calibration. The execution screen appears while the wavelength calibration is running. The execution screen will disappear when the wavelength calibration is completed. Therefore, you need to wait until the execution screen disappears. For details about wavelength calibration, see Chapter 5 in the User’s Manual for AQ2200-136 TLS Module.
