The Mini-OTDR Modes. Connecting a Fiber. Cleaning Connectors

Transcription

1 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 measurements, and apply all measurements to multiple fibers. OTDR Assistant: walk through a typical OTDR measurement, 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 movement. Blow away any remaining lint with compressed air.

2 Events Non-Reflective Event (Splice) Non-Reflective Event (Gainer) Reflective Event (Connector) Landmark End of Trace End-of-Scan Event Beginning of Trace (or a similar inverted symbol): Out-of-Range Event Reflective (left) and Non-Reflective (right) 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).

Select menu quickly: cursor away from the center of the popup menu. So, Cursor Up twice to select the File menu. Select highlighted menu option: cursor Right Close menu: cursor Left. Toggle between Realtime and Averaging measurement: hold the Run/Stop key for 2-3 seconds. Keyboard shortcuts: attach a keyboard and press <f1> for Help, <f2> for Run/Stop, and!,#,$, and & to Cursor.

4 OTDR Mode Run a Measurement [Settings] Cursor to parameters, and press. Select new settings. To set automatic settings, cursor to Auto and press. Cursor down to Ok, and press. [View]<Auto Scan> (ON) Attach fiber and press the Run/Stop key Open a Trace [File]<Open> Cursor up/down to correct file, and press Scan for Events [Settings] Select values for FrontC Thres., Refl Thres. and/or NonRefl Thres., then Ok [Analysis]<Scan Trace> Run Pass/Fail Test [Settings] Select > to reach Pass/Fail Param. page Alter settings as required, then select Ok. Run or Open trace (see above). [Analysis]<Pass/Fail Test> If test has failed, select Details. Print a Trace Connect printer to Mini-OTDR with a Centronics cable. Set printer settings (see Print Settings (Printer Setup page)) [File]<Print> Save a Trace or Template [File]<Save As...> Cursor to New Name, and press Use the on-screen keyboard to enter a name. If you are selecting a template, specify the extension.tpl Select Ok, then Save. Add Trace Information Labels [File]<Trace Info> Cursor up to each Edit field and press Use the on-screen keyboard to enter a name, then select Ok. When you have entered all labels, select Ok.

5 Source Mode Use the Power Meter Submodule Switch off the Mini-OTDR, and insert a module Insert E6006A power meter submodule into the module Attach a connector to the module. Use this to connect a fiber. Attach the other end of the fiber to a source Switch on the Mini-OTDR and select [Power Meter] Perform an Insertion Loss Measurement Insert the power meter submodule (see above) 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 wavelength 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. Examine the fiber attached to your submodule. Red light shows where there are breaks in the casing.

6 Other Mini-OTDR Modes Test for Fiber Break (Fiber Break Locator mode) Select parameters (Refr Ind, Wavelength, Threshold), and alter as required Attach fiber and press Run/Stop Wait for Averaging Time to elapse, or press Run/Stop again. Test Multiple Fibers (Multi Fiber Test mode) Select > until you see the Measurement Params page. Cursor to Measurements edit field(s) and press Select trace or template containing settings Press [Start] Connect first fiber, then select Ok Wait for Averaging Time to elapse, or press Run/Stop. Connect the next fiber, then select Ok. Continue until all fibers have been measured. Copy file from Floppy Disk (File Utility mode) Insert a floppy disk containing your file [Device]<Floppy> Cursor to file and press Select file, then Copy. Select [Device]<Internal> then Ok. Instrument Config Mode Add a logo (General Parameters page) Copy your logo (as PCX file) to your Mini (see above) [Logo]<Select> Cursor down to your logo name, and press Select Save, then OK. Connect to PC (Instrument Setup page) Attach your PC to an OTDR with a serial cable Select correct settings, select Save, then OK. Set User Experience Level (General Parameters page) Cursor to User Experience Level Select Low to see the Fiber Break Assistant in Fiber Break Locator mode Select High to hide the Fiber Break Assistant Select Save, then OK. Print Settings (Printer Setup page) Select correct settings, select Save, then OK.
