The Mini-OTDR Modes
• OTDR Mode: make, view and analyze traces
• Fiber Break Locator: simplified trace setting to locate fiber breaks quickly.
• Source Mode: enable the stabilized laser source for loss.
If a submodule is installed, this icon is labeled Power Meter or Visual Light.
• Instrument Config; set up the Mini-OTDR configuration.
• File Utility: internal directory structure of the Mini-OTDR or an added device: copy, delete, or print files.
• Easy OTDR: view a trace, perform simple operations, and apply presaved settings.
• Multi Fiber Test: measure and define up to 4 measure-ments, and apply all measurements to multiple fibers.
• OTDR Assistant: walk through a typical OTDR measure-ment, with hints about which parameters you should adjust.
• OTDR Training: general background information about using OTDRs.
Connecting a Fiber
• Clean the connectors (see below).• Attach the required optical connector interface to the
optical output.• Connect the fiber to this interface.• Turn on the Instrument.
Cleaning Connectors
• Clean the connector by rubbing a new, dry cotton swab over the surface using a small circular move-ment.
• Blow away any remaining lint with compressed air.

Events
Add Event (OTDR Mode)• Move a marker to the correct position
• ♦ [Events]<Add/Mod Refl. Event>(or [Events]<Add/Mod Non-Refl. Event> as required)
• Press ♦, Cursor left to Marker, then press ♦• Cursor Up to select a level-marker
Cursor Left/Right to move that level-marker.
• Cursor Up to the subsequent level-marker, and adjust.Repeat for other level-markers.
• Press ♦. Select Ok, then press ♦.
• If you are adding a Reflective Event, select and move level-markers as before (this time, for Insertion Loss).

• Cursor to Mod. and press ♦ until you see CW in the source window.
• Cursor to λ (r-h diagram) and press ♦ until you see correct wavelength
• Cursor to λ (l-h diagram) and press ♦ until you see wave-length of source
• Connect the module and power meter submodule with a fiber
• Cursor to On/Off, then press ♦• Cursor to dBm/W, and press ♦ until you see dB
• Wait for measurement to finish, then select Disp/Ref
• Select On/Off to turn off the source.
Use the Visual Fault Finder Submodule• Switch off the Mini-OTDR, and insert a module
• Insert E6007A visual fault finder submodule into the module
• Attach a connector to the module, then connect a fiber.
• Switch on the Mini-OTDR and select [Visual Light].
• Select Mod and alter as required. Select On/Off.
