General Information

The IQS-2600B Tunable Laser Source addresses the testing requirements for dense WDM component testing in the C- and L-bands.

Tunable Laser Source 1

The source has a medium coherence length that avoids problems such as connector-induced interference and it is relatively immune to vibration. Its linewidth is made up of several longitudinal modes that are present simultaneously, resulting in no mode-hop-related measurement problems. It also features a high-accuracy encoder for consistency in your results.

Your module may also feature the possibility to enable or disable the automatic level control (ALC).

Introducing the IQS-2600B Tunable Laser Source

Typic a l Ap pl ic ation s

The IQS-2600B Tunable Laser Source supports local control (via the IQS Manager software) and remote control (through GPIB, RS-232, or Ethernet TCP/IP using SCPI commands or the provided LabVIEW drivers). For more information, refer to the IQS platform user guide.

Typical Applications

You can use your Tunable Laser Source to perform several tasks, such as the following:

 characterizing filters, multiplexers, Bragg gratings, and other DWDM

components

 checking wavelength-dependent gain, noise contribution and

saturation properties

 determining the spectral sensitivity of receivers and detectors

 performing high-loss tests on passive components

2 IQS-2600B

Introducing the IQS-2600B Tunable Laser Source

IQS-2600CT Tunable Laser Source for IQS-12004B DWDM Passive Component Test System

EXFO has modified its IQS-2600B Tunable Laser Source in order to integrate it into the IQS-12004B DWDM Passive Component Test System. To optimize the performance of the IQS-12004B, the optical attenuator ensuring a constant power output from the tunable laser source has been removed.

You can easily identify the type of tunable laser source you have. The unit designed for the IQS-12004B system will bear the mention 2600CT, while the stand-alone unit will bear the mention 2600B.

Every customer purchasing the IQS-12004B DWDM Passive Component Test System for applications covering both the C- and L-bands will receive an IQS-2600CT model. Even though the tunable laser source has been modified, it can still be used as a stand-alone instrument using an IQS-600 Integrated Qualification System. However, you will notice a warning message when turning the instrument on.

This warning informs you that the power output is not monitored and cannot be controlled internally. Also note that the power stability and repeatability values presented in the IQS-2600B specification sheet do not apply to the IQS-2600CT.

Any other functionality or specification, particularly those concerning the accuracy of the instrument and wavelength stability, will not be affected by this design change.

Cleaning and Connecting Optical Fibers

IMPORTANT

To ensure maximum power and to avoid erroneous readings:

 Always inspect fiber ends and make sure that they are clean as

explained below before inserting them into the port. EXFO is not responsible for damage or errors caused by bad fiber cleaning or handling.

 Ensure that your patchcord has appropriate connectors. Joining

mismatched connectors will damage the ferrules.

To connect the fiber-optic cable to the port:

1. Inspect the fiber using a fiber inspection microscope. If the fiber is

clean, proceed to connecting it to the port. If the fiber is dirty, clean it as explained below.

2. Clean the fiber ends as follows:

2a. Gently wipe the fiber end with a lint-free swab dipped in isopropyl

alcohol.

2b. Use compressed air to dry completely.

2c. Visually inspect the fiber end to ensure its cleanliness.

Tunable Laser Source 35

Operating your Tunable Laser Source

Cleaning and Connecting Optical Fibers

3. Carefully align the connector and port to prevent the fiber end from touching the outside of the port or rubbing against other surfaces.

If your connector features a key, ensure that it is fully fitted into the port’s corresponding notch.

4. Push the connector in so that the fiber-optic cable is firmly in place, thus ensuring adequate contact.

If your connector features a screwsleeve, tighten the connector enough to firmly maintain the fiber in place. Do not overtighten, as this will damage the fiber and the port.

Note: If your fiber-optic cable is not properly aligned and/or connected, you will

notice heavy loss and reflection.

WARNING

Tunable Laser Source 47

Maintenance

Cleaning Fixed Connectors

Regular cleaning of connectors will help maintain optimum performance. Do not try to disassemble the unit. Doing so would break the connector.

To clean fixed connectors:

1. Fold a lint-free wiping cloth in four to form a square.

2. Moisten the center of the lint-free wiping cloth with only one drop of

isopropyl alcohol.

Alcohol may leave traces if used abundantly. Avoid contact between the tip of the bottle and the wiping cloth, and do not use bottles that distribute too much alcohol at a time.

3. Gently wipe the connector threads three times with the folded and moistened section of the wiping cloth.

IMPORTANT

Isopropyl alcohol takes approximately ten seconds to evaporate. Since isopropyl alcohol is not absolutely pure, evaporation will leave microscopic residue. Make sure you dry the surfaces before evaporation occurs.

4. With a dry lint-free wiping cloth, gently wipe the same surfaces three times with a rotating movement.

5. Throw out the wiping cloths after one use.

6. Moisten a cleaning tip (2.5 mm tip) with only one drop of isopropyl

alcohol.

IMPORTANT

Alcohol may leave traces if used abundantly. Avoid contact between the tip of the bottle and the cleaning tip, and do not use bottles that distribute too much alcohol at a time.

7. Slowly insert the cleaning tip into the connector until it reaches the ferrule inside (a slow clockwise rotating movement may help).

8. Gently turn the cleaning tip one full turn.

9. Continue to turn as you withdraw the cleaning tip.

10. Repeat steps 7 to 9, but this time with a dry cleaning tip (2.5 mm tip

provided by EXFO).

Note: Make sure you don’t touch the soft end of the cleaning tip and verify the

cleanliness of the cotton tip.

11. Throw out the cleaning tips after one use.

Cleaning EUI Connectors

Regular cleaning of EUI connectors will help maintain optimum performance. There is no need to disassemble the unit.

If any damage occurs to internal connectors, the module casing will have to be opened and a new calibration will be required.

To clean EUI connectors:

1. Remove the EUI from the instrument to expose the connector

baseplate and ferrule.

IMPORTANT

2. Moisten a 2.5 mm cleaning tip with one drop of isopropyl alcohol (alcohol may leave traces if used abundantly).

3. Slowly insert the cleaning tip into the EUI adapter until it comes out on the other side (a slow clockwise rotating movement may help).

4. Gently turn the cleaning tip one full turn, then continue to turn as you withdraw it.

50 IQS-2600B

Cleaning EUI Connectors

5. Repeat steps 3 to 4 with a dry cleaning tip.

Note: Make sure you don’t touch the soft end of the cleaning tip.

6. Clean the ferrule in the connector port as follows:

6a. Deposit one drop of isopropyl alcohol on a lint-free wiping cloth.

IMPORTANT

Isopropyl alcohol may leave residues if used abundantly or left to evaporate (about 10 seconds).

Avoid contact between the tip of the bottle and the wiping cloth, and dry the surface quickly.

6b. Gently wipe the connector and ferrule.

6c. With a dry lint-free wiping cloth, gently wipe the same surfaces to

ensure that the connector and ferrule are perfectly dry.

6d. Verify connector surface with a portable fiber-optic microscope

(for example, EXFO’s FOMS) or inspection probe (for example, EXFO’s FIP).

Maintenance

WARNING

Verifying the surface of the connector WHILE THE UNIT IS ACTIVE WILL result in permanent eye damage.

7. Put the EUI back onto the instrument (push and turn clockwise).

8. Throw out cleaning tips and wiping cloths after one use.

Maintenance

Adjusting Your Unit According to Wavelength

It is possible to introduce an offset in your Tunable Laser Source to correct a wavelength deviation as measured by a reference wavelength meter.

Note: A calibrated wavelength meter is required to perform a user calibration on

your unit.

To adjust your module at a certain wavelength:

1. Turn your Tunable Laser Source on.

2. Set your Tunable Laser Source at the desired wavelength as explained

in Selecting a Wavelength on page 20.

3. Select the Settings function tab.

4. Click the User Calibration tab.

5. Connect your IQS-2600B to a calibrated wavelength meter and enter

the measured wavelength in the corresponding box.

6. Click Adjust. Your unit will verify if there is a difference between the value you have entered and its current wavelength position. If there is a difference, it will add an offset to compensate.

This user-performed calibration feature can help you achieve better absolute wavelength accuracy if, for example, you feel that conditions outside the unit may have affected the calibration.

52 IQS-2600B

Maintenance

Adjusting Your Unit According to Wavelength

The difference between the pre-selected wavelength and the measured wavelength cannot be greater than ± 0.200 nm. If the difference between the measured and preselected wavelengths is greater than ± 0.200 nm (for example, if you have entered the wrong value), an error message will be generated.

IMPORTANT

Note that the offset introduced into the Tunable Laser Source with this software feature cannot be disabled. To correct for a handling error during the procedure, you must repeat the steps described above with a calibrated wavelength meter.

Tunable Laser Source 53

Maintenance

Recalibrating the Unit

Manufacturing and service center calibrations are based on the ISO/IEC 17025 Standard, which states that calibration documents must not contain a recommended calibration interval, unless this has been previously agreed upon with the customer.

Validity of specifications depends on operating conditions. For example, the calibration validity period can be longer or shorter depending on the intensity of use, environmental conditions and unit maintenance. You should determine the adequate calibration interval for your unit according to your accuracy requirements.

Under normal use, EXFO recommends calibrating your unit every year.
