Setting Up Your Multifunction Loss Tester Cleaning and Connecting Optical Fibers 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.
Setting Up Your Multifunction Loss Tester 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.
Setting Autonaming Scheme Setting Autonaming Scheme Initially, the unit suggests cable and fiber names based on autonaming settings. After saving a result, the unit prepares the next fiber name by incrementing the suffix (or by adding “001” to a name with no suffix). When you manually change the name for the first time (in Power Meter, ORL Meter or FASTEST), the unit then ignores autonaming settings. IMPORTANT To start using new autonaming settings, you must delete all cables from memory.
Setting Autonaming Scheme To set the autonaming scheme: 1. Press Menu, then select Setup > Data Autonaming. 2. Use the arrows to select the cable prefix, cable number or fiber prefix. 3.

Measuring Power or Loss Nulling Electrical Offsets Nulling Electrical Offsets Temperature and humidity variations affect the performance of electronic circuits and optical detectors. Nulling the electrical offsets eliminate these effects. Your unit has been designed not to require offset nulling under normal operation, but you should perform it whenever environmental conditions change significantly or when measuring very low power values. IMPORTANT Light must not reach detectors when nulling offsets.
Measuring Power or Loss Referencing Your Power Meter to a Source Referencing Your Power Meter to a Source In reference mode, your unit displays the loss created by the fiber under test only, since it subtracts a reference value from the measured power. In the illustration, the reference value (-36.87 dBm) is subtracted from the actual power measured (-7.89 dBm).
Measuring Power or Loss Referencing Your Power Meter to a Source To reference the power meter to a source: 1. Press Menu, then select Power Meter. 2. Check your fibers and clean them properly for optimum performance (see Cleaning and Connecting Optical Fibers on page 22). 3.
