  • Page 14: Cleaning And Connecting Optical Fibers

    To ensure maximum power and to avoid erroneous readings: Always clean fiber ends 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.

  • Page 15: Measuring Power Or Loss (Epm-500 And Eot-500)

    4 Measuring Power or Loss (EPM-500 and EOT-500) Nulling Electrical Offsets Temperature and humidity variations affect the performance of electronic circuits and optical detectors. Nulling the electrical offsets eliminates 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.

  • Page 16: Referencing Your Power Meter To A Source

    Measuring Power or Loss (EPM-500 and EOT-500) Referencing Your Power Meter to a Source In reference mode, your unit displays the loss created by the fiber under test only, since a reference value is subtracted from the measured power. Note: You must set a reference value separately for each wavelength.

  • Page 17: Measuring Power Or Loss

    2. Check and clean your fibers appropriately for optimum performance (see Cleaning and Connecting Optical Fibers on page 9). 3. For loss measurements, reference your power meter to a light source (see Referencing Your Power Meter to a Source on page 11), then deactivate the light source. EPM-500/ELS-500/EOT-500...
  • Page 18 Measuring Power or Loss (EPM-500 and EOT-500) 4. Using the proper adapter and test jumpers, connect a fiber under test to a light source (such as ELS-500 or EOT-500) and to the detector port of your unit. Note: If you have referenced your power meter to a source, simply connect a fiber under test to the test jumpers used for referencing.

  • Page 19: Automatically Detecting Wavelength

    ELS-500: see Modulating the Source Signal on page 17) or in auto-switching mode (see Using Auto-Switching Mode on page 17). Your power meter automatically matches the source wavelength. If the wavelengths differ, it also beeps and returns you to normal operating mode. EPM-500/ELS-500/EOT-500...

  • Page 20: Setting Pass/Fail Thresholds

    Measuring Power or Loss (EPM-500 and EOT-500) Setting Pass/Fail Thresholds You can define thresholds to specify acceptable power (dBm) or loss (dB) values for each wavelength. Thresholds are often supplied by system manufacturers and depend on the system deployed. When a threshold is activated, the PASS/FAIL LED is turned on.

  • Page 21: Using A Light Source (Els-500 And Eot-500) Or Vfl

    (two-port models). The EOT-500 may contain up to three sources. Note: The VFL option may also be present on the EPM-500. Activating/Deactivating a Light Source or VFL Only one source may be active at a time. When no source is active, the unit displays OFF.

  • Page 22: Modulating The Source Signal

    Using a Light Source (ELS-500 and EOT-500) or VFL Modulating the Source Signal When you activate the first source (after turning on the unit), the signal is always CW (unmodulated). When you switch sources, the modulation remains the same (VFL remembers its own modulation). Modulation is indicated in the top left (port #1) or top right (port #2) corner.

  • Page 23: Sending Source Power Value With Signal

    Your source can transmit a user-defined power value to compatible power meters (such as EOT-500 and EPM-500) through the fiber. If the reference source is far from the power meter, you can connect your source to the power meter to send the reference value.
  • Page 24 Using a Light Source (ELS-500 and EOT-500) or VFL To use the actual source output power as reference (EOT-500 only): 1. Connect a fiber between the source and power meter of same unit. 2. Activate the source at the desired wavelength. 3.

    5. While a digit blinks, hold down a few seconds to save the modified value (it remains in memory even when you turn off the unit) or press to return to the previous value without saving. 6. Press twice to exit setup menus. EPM-500/ELS-500/EOT-500...

  • Page 26: Saving, Recalling And Deleting Data

    Saving and Recalling Power/Loss Values Saving, Recalling and Deleting Data MPORTANT You cannot recover deleted data. Ensure that you transfer your data to a computer if you intend to use it later. Deleting a single value does not free memory. To free memory, you must delete all data at once.
  • Page 27 Recall indicator is displayed with the last cable name, then the last saved value and its fiber ID. 2. When fiber ID is displayed, hold down both a few seconds. The unit displays “dEL” and “ALL”, then automatically returns to normal mode. EPM-500/ELS-500/EOT-500...

  • Page 28: Transferring Data To A Computer

    Saving and Recalling Power/Loss Values Transferring Data to a Computer Using an appropriate USB cable and the Handheld Data Transfer software, you can transfer saved data from your handheld unit to a computer. This way, you can increase storage capacity, perform better analyses on your data and create reports. MPORTANT Transferred data is not automatically deleted from your unit.

  • Page 29: Maintenance

    If any liquids are spilled on or into the unit, turn off the power immediately and let the unit dry completely. ARNING Use of controls, adjustments and procedures for operation and maintenance other than those specified herein may result in hazardous radiation exposure. EPM-500/ELS-500/EOT-500...

  • Page 30: Cleaning Eui Connectors

    Pull Push 2. Moisten a 2.5 mm cleaning tip provided by EXFO 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).
  • Page 31 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 (e.g., EXFO’s FOMS) or fiber inspection probe (e.g., EXFO’s FIP). ARNING Verifying the surface of the connector WHILE THE UNIT IS ACTIVE WILL result in permanent eye damage.

  • Page 32: Cleaning Detector Ports

    Maintenance Cleaning Detector Ports Regular cleaning of detectors will help maintain measurement accuracy. MPORTANT Always cover detectors with protective caps when unit is not in use. To clean detector ports: 1. Remove the protective cap and adapter (FOA) from the detector. 2.
