3. Fiber Basics: Connectors
Body
Ferrule
Fiber
Body
The connector body holds the ferrule and holds the fiber in place
Ferrule
Thin cylinder where the fiber is mounted; acts as the fiber alignment mechanism; the end of the fiber is located at the end of the ferrule
Fiber
Cladding
Optical fiber layer (lower refractive index) that has direct contact with the Core layer. Typically 125μ in diameter.
Core
The critical center layer of the fiber (total internal reflection) where light passes through. Typically 9μ for singlemode fiber.
LC Connector

4. Why Inspect? Dirt & Contamination
Contamination is the number one cause of troubleshooting in optical networks
Contaminated connectors that are mated cause embedded debris and pits, which are permanent forms of damage
Contamination must be removed prior to mating connectors
Clean
Dirt
Pit

5. Inspect before you connect!
Note: For specific information regarding the AT&T cleaning procedures, please reference ATT-TELCO

23. Fiber Inspection Procedures
Simplex Patch Cords
Switch/toggle the “A/B” button to turn the patch cord module ON (red indicator).
Remove the dust cap from the patch cord and place in an anti-static (ESD-sensitive) bag (save/secure the dust cap for later use).
Insert the patch cord into the patch cord module and focus the image to inspect.

27. Cleaning Tools CLEANER FIBER OPTIC MPO (PID 310095690)
Note: AT&T has recently updated cleaning procedures by transition away from using swabs for bulkhead cleaning. The new procedures involve use of the tools shown below. Further details on these procedures can be found in ATT-TELCO
CLEANER FIBER OPTIC MPO (PID )
Used for cleaning the ferrule end faces of MPO connectors. This device cleans all 12 fibers at once. Capable of cleaning ferrules with or without guide pins. Cleaning count: 500
FERRULE MATE SFM-250 (PID )
Used for cleaning the ferrule end faces of 2.5mm simplex fiber connectors (ex: SC, ST, FC). Cleaning count: 350
FERRULE MATE SFM-125 (PID )
Used for cleaning the ferrule end faces of 1.25mm simplex fiber connectors (ex: LC). Cleaning count: 350

28. Inspect before you connect!
Note: For specific information regarding the AT&T cleaning procedures, please reference ATT-TELCO

29. Grading Fiber: Pass Fail Criteria
Dirt & Defects
Pass/Fail criteria for AT&T can be found in the following section of ATT-TELCO :
The Universal Grading Template is only used when there is a defect that can not be removed in the cleaning process described in ATT-TELCO

30. Grading Fiber: Pass Fail Criteria
Dirt & Defects
Identify the debris and defects which can not be removed
To grade these defects, place the template over the fiber on the “low” side
Use the “Keys to Zone” section of the template to determine in which zone the identified defects are located
Use the reference dots on the template to identify the size of the defects
Refer to the appropriate table for Pass/Fail Criteria in ATT-TELCO

31. Grading Fiber: Pass / Fail Criteria
The following Pass/Fail criteria can be found in ATT-TELCO
Suggestion: Keep this criteria readily available when inspecting (print and keep in kit with grading guide).

32. Maintenance Contamination
In general, this kit requires little or no maintenance. However, there are issues that can arise and it’s important to know how to recognize when the unit needs service.
If the optical system becomes contaminated, it can degrade the image quality. There are 3 symptoms of this condition:
Camera Sensor Contamination
Lens Contamination
Tip Contamination
Note: All service work is performed at Westover Scientific’s factory just outside Seattle, Washington.

33. Camera Sensor Contamination
This sort of contamination will show as a black spot. These spots look like dirt on the fiber and it can be difficult to determine if the dirt you see is on the fiber or on the camera. There is a simple way to discern the difference.
If you suspect the camera may have been contaminated:
Insert a fiber, focus and rotate the probe or the fiber…
If the black spot stays in one place on the display while the image moves, then there is dirt on the camera and it is in need of service
If the black spot moves around the display with the fiber image, then it is on the fiber
Black Spot (Dirt)
Camera Sensor Contamination
Note: All service work is performed at Westover Scientific’s factory just outside Seattle, Washington.

34. Lens Contamination
If there is a lens contamination, it creates a brown or gray shadow on the display image. Most users will never notice this, but if you do and would like to fix it, ship it back to the factory for cleaning.
This type of contamination does not impact the scope’s ability to perform well, as you can still see and discern all details of the fiber.
Shadow
Lens Contamination
Note: All service work is performed at Westover Scientific’s factory just outside Seattle, Washington.

35. Tip Contamination
The tips in this kit all have self-contained, recessed imaging lenses within them. As such, they can become contaminated through regular use.
Contamination of these lenses will not affect the image until they are heavily covered. If this occurs, the image will become uniformly cloudy. You will see a haze across the entire image
Tip Contamination
Note: All service work is performed at Westover Scientific’s factory just outside Seattle, Washington.

36. Maintenance
The probe and display are ruggedized and should fair very well over their life in the field. Nevertheless, they are electro-optical devices and should be handled with care whenever possible.
The tips are somewhat more sensitive and should be protected as best possible. All of the tips should be stored in the provided plastic bags and hard case when not being used.
