4 Preparing Your OSA/OCA for a

Test

IMPORTANT

For optimal test results, you should allow a minimum warm up period of two hours for your OSA/OCA before starting your tests.

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.

OSA/OCA 17

Preparing Your OSA/OCA for a Test

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.

Preparing Your OSA/OCA for a Test

Nulling Electrical Offsets

The offset nulling process provides a zero-power reference measurement, thus eliminating the effects of electronic offsets and dark current due to detectors.

Temperature and humidity variations affect the performance of electronic circuits and optical detectors. For this reason, EXFO recommends performing a nulling of the electrical offsets whenever environmental conditions change.

Nulling can be performed for all tests modes. In addition, a nulling is performed automatically each time you start the OSA/OCA application, and at regular intervals afterwards.

Note: You cannot perform an offset nulling in the offline version of the

application.

To perform an offset nulling:

1. From the main window, select the Acquisition tab.

OSA/OCA 23

Preparing Your OSA/OCA for a Test

Performing User Calibration

Calibrating your module can help you achieve better results. It is particularly important when the measurement accuracy is critical or when your OSA/OCA has experienced unusual shock or vibrations. To reach the highest possible accuracy, you can perform a wavelength or power calibration. Your OSA/OCA allows you to modify and read the user calibration values, revert to the factory calibration, load and save the modified user calibration file. The user configuration file (*.txt) contains the reference and modified wavelength and power values.

You can perform user calibration in any test mode. Select a test mode as explained in Selecting a Test Mode on page 20, and follow the procedures mentioned below for performing user calibration.

Note: The procedure is not available for the OCA application.

Note: The procedure for performing user calibration is the same for all test

modes. The procedure is explained with WDM mode only in this document.

IMPORTANT

For optimal results, you should allow a minimum warm up period of two hours for your OSA/OCA before performing user calibration.

IMPORTANT

You must clear the correction factor list before making new calibration measurements. If calibration measurements are made when user correction factors are inside the module, the latter will affect the measurements and the calibration results become inapplicable.

Note: If you want to keep the correction factor list for a later use, save it under a

different name in the folder.

You can set up your unit in different manners, depending on your testing needs.

 The preferred way is to use the complete analysis setup parameters

and complete the information in all tables, as explained in Setting Up WDM Analysis Parameters on page 61. This setup will be used for the

next acquisition.

 The easiest way to set up the instrument, especially when the operator

does not know in advance what to expect at the input of the module is to use the Discover button. After the Discover button has been pressed, a measurement and analysis will be performed according to the best setup determined by the instrument and this setup will be used for the next scan. This is explained in Using the Discover Feature on page 155.

 The most efficient way to set up the instrument is to use one of the

favorites configurations, uploading a pre-customized acquisition and analysis setup configuration. The operator in the field only has to press the button, select the appropriate configuration and press Start. As an example, a pre-customized configuration could be: “32 channels DWDM 50GHz”; “Toronto-Montreal CWDM” or “Vendor ABC DWDM ROADM 40Gb”. This is explained in Managing Favorites on page 163.

66 FTB-5230S/-OCA

Setting Up the Instrument in WDM Mode

Setting Up WDM Analysis Parameters

 Channel width (GHz or nm): indicates the limit inside which the

power values will be considered in the channel.

For default channels, the channel width that sets the limits of the channel, should be the same as the channel distance or smaller (channel distance is defined while creating a channel list). If the channel width is not compatible with the channel spacing, either a single peak may be found for two distinct channels and two analysis would be performed and displayed for that peak, or, it is possible that two peaks may be found within the same channel and be considered as one multi-peak signal. With this result, you can use markers to find the spacing between adjacent channels or to find the channel width.

 Snap to ITU Grid: When selected, each detected peak will be

defined by the nearest ITU channel. The ITU grid is based on the selected channel width.

 Signal power calculation: indicates which calculation method to

apply for signal power value.

Integrated signal power: The integrated signal power represents the sum of the power values included between the channel limits of this channel, minus the estimated noise contribution between the same boundaries. In some cases, for instance CATV signals, signals with high-frequency modulation, or signals with an inherent line width similar or larger than the OSA/OCA's resolution bandwidth, this calculation becomes a better estimation of the true signal power.

OSA/OCA 67

Setting Up the Instrument in WDM Mode

Setting Up WDM Analysis Parameters

Peak signal power: The peak signal power represents the

maximum power value inside the channel. Note that it differs a little from the peak measurement on the spectrum due to the fact that the estimated noise is subtracted to get the peak signal power.

Total channel power: The total channel power represents the sum of the integrated signal power and of the noise within the channel. The OSNR calculation is not performed when the signal power calculation type is the total channel power.

 Noise for OSNR: indicates which calculation method to use for

OSNR value (InBand and InBand narrow filter are available for viewing or reanalysis purposes only when opening files from other OSA models).

Fixed range IEC based (IEC): The IEC method uses the interpolation of noise measured on both sides of the signal to estimate the noise level. The position at which the noise is estimated from the center wavelength is given by the OSNR distance.

InBand (InB): The InBand method uses a series of scans having different polarization states to calculate the noise level under the peak (InBand).

InBand narrow filter (InB nf): The InBand narrow filter method uses additional processing to provide an accurate OSNR value for the narrow carved noise. This is because with narrow filters, the noise level under the peak is not uniform and the OSNR value depends on the processing width selected.

Fifth order polynomial fit (Fit): The fifth order polyfit method calculates the noise curve and thus the signal to noise ratio. The OSA will approximate the noise curve using a fifth order polynomial fit. This fit definition relies on fit and exclusion zones. Only the points in the fit zones are used to calculate the fifth order polynomial fit. If you select the fifth order polyfit method, you have

to define the fit and exclusion zones for your tests using the OSNR distance and noise region fields. The exclusion zone is indirectly obtained from the OSNR distance.

 OSNR distance (GHz or nm): Except for the fifth order polyfit

selection, the OSNR distance is automatically set at the channel edge, that is, at half of the channel width from the center wavelength.

For the fifth order polyfit, the OSNR distance corresponds to the distance from the channel peak to the center of the fit zone. It is independent of the channel width.

 Noise region: The noise region, or fit zone, defines the region

where the polynomial fit applies. Two identical regions are centered at the OSNR distance.

4. Under Global analysis parameters, define the following parameters as needed:

 Peak detection level (dBm): indicates the minimum power level

from where the peak can be considered as a signal.

 RBW for OSNR (nm): indicates the resolution bandwidth selected

for the OSNR calculation. This parameter is generally set to 0.1 nm to allow for a common basis of comparison between different OSA/OCAs having different effective resolutions. The instrument’s RBW value is written below the graph. This parameter does not actually have an effect on the acquisition, but is only a normalization factor used to provide the OSNR value in a standardized manner.

 Wavelength offset (nm): indicates the offset value applied on the

wavelength. This does not replace a calibration performed at EXFO, but it can help you temporarily sharpen the specifications if you have determined that, for example, your modules are used beyond the normal allowed use. Entering a value in THz is not possible. When an offset is applied, it is indicated at the bottom of the graph ( ).

 Power offset (dB): indicates the offset value applied on the power.

This does not replace a calibration performed at EXFO, but it can help you achieve the specifications if you have determined that, for example, your modules are used beyond the normal allowed use. When an offset is applied, it is indicated at the bottom of the graph (P ).
