Inspecting Fibers with the DFS1

The following instructions assume the DFS1 is configured with the appropriate adapter tip

installed, an appropriate device (M-Series OTDR or C-Series OTDR or Certification Tester)

is powered up, the DFS1 operation mode is selected, the DFS1 is connected to the OTDR/

Tester USB port, DFS1 initialization has completed, and real-time images from the DFS1

are currently being displayed on the OTDR/Tester screen.

1. If testing an optical fiber connector:

– Slide the ferrule of the optical fiber into the installed adapter probe tip, using caution

not to contaminate the end-face of the fiber connector.

– A dark circle will appear on the attached device display.

2. If testing an optical fiber connector mounted in a bulkhead adapter:

– Slide the probe adapter tip into the bulkhead adapter.

– Adjust the angle of the adapter tip until a dark circle appears on the attached device

display.

3. If the edges of the displayed dark circle are fuzzy:

– Rotate the Focus Adjust Knob on the DFS1 clockwise or counter-clockwise until the

displayed circle is in sharp focus.

4. If display sharpness or contrast is poor:

– Press the Settings function key, adjust the contrast and sharpness.

– Press Apply to save the adjusted settings.

– Then press Settings to return to image display.

5. Once a good image has been obtained, it may be captured and archived either by

pressing the Display Capture button on the DFS1, or by pressing the Snap function key

on the attached OTDR or Tester.

– Either of these actions results in the OTDR/Tester displaying the message "Saving."

– If an image for the identified fiber number, cable ID, and fiber end already exists, the

OTDR/Tester will prompt "The file already exists. Would you like to overwrite the file?"

– Press Yes or No to complete or abort the image capture.

– Once the image has been captured, the fiber number is incremented.

6. Remove the probe adapter from the inspected fiber and repeat the process for

subsequent fibers.

7. Clean, undamaged fibers should display with no dark spots showing on the fiber end-

face. If dark spots are displayed on the fiber end-face, the fiber end should be cleaned

using the appropriate cleaning stick (One-Click Cleaner) or wipe.
