Fiber Basics: ConnectorsFiber Basics: Connectors

BodyThe connector body holds the ferrule and holds the fiber in place

FerruleThin 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.

Why Inspect?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

Cleaning ToolsCleaning Tools

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-

002-200-381

CLEANER FIBER OPTIC MPO (PID 310095690)

12 fibers at once. Capable of cleaning ferrules with or without guide pins.

Cleaning count: 500

FERRULE MATE SFM-250 (PID 310111984)

Dirt & Defects

Grading Fiber: Pass Fail CriteriaGrading Fiber: Pass Fail Criteria

Pass/Fail criteria for AT&T can be found in the following section of ATT-TELCO-002-200-381:

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-002-200-381

30

Dirt & Defects

Grading Fiber: Pass Fail CriteriaGrading Fiber: Pass Fail Criteria

• 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-0020200-381

31

Grading Fiber: Pass / Fail CriteriaGrading Fiber: Pass / Fail Criteria

• The following Pass/Fail criteria can be found in ATT-TELCO-002-200-381

MaintenanceMaintenance

Contamination

Note: All service work is performed at Westover Scientific’s factory just outside Seattle, Washington.

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

33

Camera Sensor ContaminationCamera Sensor Contamination

• 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.

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…

34

Lens ContaminationLens Contamination

ShadowLens 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.

Note: All service work is performed at Westover Scientific’s factory just outside Seattle, Washington.

35

Tip ContaminationTip Contamination

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

Note: All service work is performed at Westover Scientific’s factory just outside Seattle, Washington.

36

MaintenanceMaintenance

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.
