4 OTDR Test Modes Settings The OFL250 offers four OTDR test modes (Full Auto, End Locate, Live, & Expert) and Light Source & Power Meter test mode. The OTDR Mode setting determines which other settings may be changed by the user ( ) and which are set by the OFL250 automatically. Settings for each OTDR Test mode are summarized below: Test Modes Settings Full Auto End Locate Live Expert Wavelength Auto Setup Range Auto Filter Auto Pulse Averaging Auto Events Auto End Locate N/A Thresholds N/A Fiber Type Index BC Launch Cable & Launch Cable Length Receive Cable & Receive Cable Length Distance Units Thresholds in Full Auto and Expert mode Threshold Value Min Default Max End Loss 1.0 db 3.0 db 6.0 db Event Loss 0.02 db 0.10 db 2.00 db Event Reflectance db db db Event Thresholds in End Locate mode Threshold Value Min Default Max End Loss 1.0 db 3.0 db 6.0 db 4

5 To Start a Test - Press the To Stop a Test Running Tests & Viewing Results Test key Press the Test key. If pressed before trace appears, will stop the test and display the setup menu. If pressed after trace appears, it will stop the test and show the partially completed trace. Press the Selecting the Test View Back key. The OFL250 stops the test and displays the setup menu. The OFL250 test results can be displayed using different Views or Pages. Each Page presents a different view of the current or saved test. Each Page is identified by the corresponding tab as illustrated below db i Test Viewer tabs. Note: End-to-end Summary tab (db icon) only present if ORL upgrade option installed. To display the desired Page for viewing press Left and Right Tab keys Test Views (Pages) Description ICON NAME DESCRIPTION Trace Displays OTDR trace, A/B cursors, Loss and Distance between A and B cursors, and reflectance.

In the Full Auto and End Locate modes, Events are set to Auto by default. 2. In the Expert test mode, set Events (Events menu) to Auto. Trace Graph. Event Table displays events location in user selected units, event type, reflectance and loss in (db) WAVE 1550 No Location (m) Type Refl (db) Loss (db) 1 xxxx xxxx xxxx 2 xxxx xxxx xxxx ZOOM db i Event Icons and Types Icon Event Type and Description Start of the fiber under test: Indicates start of launch cable when a launch cable is present. End of the fiber under test: Indicates end of receive cable when a receive cable is present. Reflective Event: An event with measurable loss and reflectance, typically caused by a connection or mechanical splice. Non-Reflective Event: An event with measurable loss but very small or unmeasurable reflectance, typically caused by a splice or bend in the fiber. Gainer: An event with negative loss, which can occur in OTDR traces where two fibers with very different backscatter coefficients are spliced or connected. Normally a gainer will be seen as a normal (positive loss) event when tested from the other end of the fiber. The true loss of the event causing the gainer is the approximately equal to the average of its loss measured from each end of the fiber under test. Multiple Event: An event table entry that accounts for two or more physical (real) events that are too close together to be measured separately by the OTDR, for example the start and end of a short jumper. The loss of a multiple event is the sum of the losses of the physical events that comprise it. 7

8 End-to-end Summary Page End-to-end Summary Page Features (ORL Upgrade Required) If the ORL Upgrade option is installed, the end-to-end Summary is always generated if testing in the Full Auto or End Locate modes. The end-to-end Summary is also generated in the Expert test mode if Auto event generation is enabled. The end-to-end Summary displays the following information: End-to-end Length in user-selected distance units. End-to-end Link Loss in db. Optical Return Loss (ORL) in db. For most accurate results, use Launch & Receive cables Loss and ORL include first and last connector of fiber-under-test when Launch & Receive cables are used. Receive cable properly terminates open far-end connector. If no receive cable is used, open PC connector at far-end will cause poor (low) ORL. ORL displayed as < nn.nn if fiber-under-test includes a saturated (clipped) reflection. ORL < 30 db generally indicates presence of one or more strong reflections. ORL < 20 db indicates likely air gap at connector, break, or open PC end. 8

Large reflection at open end of receive cable is excluded from ORL. Summary displays end-to-end Link Length, Loss and ORL. Loss & ORL include first and last connection to fiber-under-test. Loss & ORL excludes reflection and backscatter from launch & receive cables, as well as excess reflection from open end at far-end of receive cable. 9

10 File Manager System Saving Test Results The OFL250 File Manager system consists of three pages as follows: Page Name Folders page Files page Save As page Description Displays a list of saved folders in OFL250 internal memory. Used to select the current folder or delete folders. Displays a list of saved files in the current folder.

12 Opening a Trace File for Review Opening Files (Reviewing Saved Results) Access the File Manager - Files page. Use keys to highlight the desired file. Press the Open soft key to display test results. Transferring Files to your PC To transfer files from your OFL250 to a PC using a USB cable, perform the following: 1. Connect your OFL250 to a PC using a type A to Mini USB B cable. Make sure the mini-plug is fully seated in your OFL Press the USB soft key on the OFL On your PC, open My Computer. A new removable drive named OFL X: will appear, where X: is the drive letter assigned to your OFL Under OFL X: you should see two folders: RESULTS and SOFTWARE. Copy the RESULTS folder to your PC. 5. Under RESULTS you will see: TRACES. Under TRACES you will see all of the folders containing traces. Note: Before removing the USB cable connecting your OFL250 to your PC, or pressing the Cancel soft key on the USB page, left click the Safely Remove Hardware icon in the Start bar of your PC, then left click the Safely remove USB mass storage device Drive (X:) message, where X is the drive letter assigned to your OFL250.
