Basic Switching Principles

The switch ports of 1 x N optical switches are numbered on the front panel, while the common port is identified with a "C."

These switches are bidirectional. This means that the optical signal can either enter through the common port and be directed toward any switch port, or enter through any switch port and then be directed toward the common port.

The IQS-9100-02-02 (2  2 model) is also a bidirectional switch. The two positions for this switch are known as inserted state and bypass state.

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.

Optical Switch 29

Page 36

Operating the Optical Switch

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.

EXFO uses good quality connectors in compliance with EIA-455-21A standards.

To keep connectors clean and in good condition, EXFO strongly recommends inspecting them with a fiber inspection probe before connecting them. Failure to do so will result in permanent damage to the connectors and degradation in measurements.

Operating the Optical Switch

Optimizing the Application for Repeatability

The optimization for repeatability ensures better accuracy in positioning the light path when switching.

 With optimization activated, every time a switching occurs, the switch

mechanism returns to the “no continuity” (Off) position before aligning to a new channel position. This option provides better precision, but with slower switching.

 With optimization deactivated, the switch mechanism goes directly to

the new channel position. This option provides faster switching, but with less precision.

Note: This option is NOT available in the 1 x 2, 2 x 2 and 2 x 4 models.

To optimize switching for repeatability:

1. In the main window, select the Settings function tab.

2. Click the Optimize for Repeatability button. The light indicator on the

button will turn bright green to indicate optimization is active.

4 Controlling Multiple Optical

Switch Modules

With your platform, you can set common parameters and simultaneously operate several modules of the same kind in a single interface, which is particularly useful in larger systems.

Note: You should be familiar with the configuration and operation of a single

module before controlling multiple modules simultaneously.

Starting a Multimodule Application

The multimodule applications available will change according to your module configuration (model, type, etc.).

Note: When you start a multimodule application, you cannot open a monitor

window at the same time, as it is possible with a single-module application. You must open the monitor window independently.

To start a multimodule application:

1. In IQS Manager, select the Integrated Applications function tab.

2. Click the appropriate Multiple Module Controller button.

The multimodule application appears in a new window.

Note: More than one Multiple Module Controller button may be displayed if

different models are present in your platform.

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.

54 IQS-9100/9100B

Page 63

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 fiber 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.
