Setting Up Your Multifunction Loss Tester Installing the EXFO Universal Interface (EUI) The EUI fixed baseplate is available for connectors with angled (APC) or non-angled (UPC) polishing. A green border around the baseplate indicates that it is for APC-type connectors.
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.
Page 31
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.

Optical return loss (ORL) is the total effect of multiple reflections and scattering events within a fiber-optic system. The FOT-930 Multifunction Loss Tester is equipped with an ORL meter to measure ORL for singlemode fibers. The ORL meter uses the F T SM (singlemode) port only.
To set the ORL zero value (all wavelengths at once): 1. Press Menu, then select ORL Meter. 2. Press ORL Zero (F1/F2 key). 3. Connect a patchcord to the F T SM port. Termination Component under test FOT-930...

Measuring Optical Return Loss Performing and Saving ORL Measurements 7. Perform an ORL zero measurement (see Performing ORL Reference and Setting ORL Zero Value on page 42). 8. Terminate the fiber as close as possible after the component under test. Wrap it at least 10 turns around a mandrel or small diameter tool, adding turns until the reading stabilizes.
T cuts down on training time and provides error-free results. To use F T, you need a compatible unit (such as FTB-3930, FOT-930, FOT-920 or FTB-3920, but not the FOT-910). The unit at the remote end is only used to establish references. It then waits for commands from the unit initiating F T (master).
Setup includes the following elements: Port and DUT (fiber) type: multimode T will not include ORL. Compatibility: select FOT-930 for fast, two- or three-wavelength testing including ORL (it requires two FOT-930/FTB-3930). Use FOT-920 when other unit is an FOT-920 or FTB-3920.

Managing Test Results Transferring Test Results to a Computer 2. Turn on both the computer and your handheld unit. Ensure that your unit will remain on during the transfer (connect it to a power outlet and deactivate auto-off). 3. On the computer, launch the Handheld Data Transfer application and start the operation.
10 Using a Light Source Your unit may contain two source ports: a 2- or 3-wavelength singlemode port and a 2-wavelength multimode port, depending on the configuration (see Technical Specifications on page 93). The source signal can be continuous (CW or high-power) or modulated (270 Hz, 1 kHz or 2 kHz) and uses the F T ports.
Page 68
Use the arrows to open the wavelength list and select Off. To change the signal modulation: 1. Activate the source if you want. 2. Press Modulation (F1/F2 key) to switch between available modulations. 3. Use the arrows to open the list and select the desired modulation. FOT-930...
11 Identifying Fiber Faults Visually The visual fault locator (VFL) helps you identify bends, faulty connectors, splices and other causes of signal loss. From its dedicated port, the VFL emits a red signal which becomes visible at the location of a fault on the fiber. This signal can be continuous (CW, the default) or blinking (1 Hz).
Page 70
5. Without looking directly into the beam, examine the fiber. If light is coming out of the rubber jacket or on the side of the ferrule, the fiber is defective. 6. Deactivate the VFL by pressing VFL On/Off (F1/F2 key). FOT-930...
Magnification control: supports 200x, 400x or other zoom factors. Focus control: allows you to fine-tune the display quality. Image capture: freezes the image on the FOT-930 display by pressing a button. For more information, refer to the user guide that came with your probe.
To facilitate communication between opposite ends of a fiber (especially on models with no talk set), you may send text messages to compatible units (such as FOT-930, FTB-3930, FOT-920 or FTB-3920) through their T ports. It is possible to send a predefined message or to write one of your own (maximum 30 characters).
Page 74
1. Connect the units at each end of the same fiber via their F T ports. 2. On the sending unit, press Menu, then select Talk Set/Messages > Messages (units with a talk set) or Messages (units with no talk set). FOT-930...
