WHY Inspect? Dirt Damages Fiber!
Mating dirty connectors embeds the debris into the fiber.
Once embedded debris is removed, pits and chips remain in the fiber.
These pits can also prevent transmission of light, causing back reflection, insertion loss and damage to other network components.
Most connectors are not inspected until the problem is detected… AFTER permanent damage has already occurred.
DIRT HAPPENS
Each time the connectors are mated, particles around the core are displaced, causing them to migrate and spread across the fiber surface.
Particles larger than 5µ usually explode and multiply upon mating.
Actual fiber end face images of particle migration
Large particles can create barriers (“air gaps”) that prevent physical contact.
Particles less than 5µ tend to embed into the fiber surface, creating pits and chips.
Best Practice for Fiber Handling
Proactive inspection saves time and money instead of just replacing connectors.
Proactive inspection reduces “Re-Work”
A Clean Fiber vs. a Dirty Fiber
A clean fiber will ensure a proper connection and minimize LOSS and REFLECTIONS.

Dirt
Oil
Pits & Chips
Scratches
Singlemode Fiber
Each of these contaminates will cause issues with connections and service.

Proactive vs. Reactive Inspection
Proactive Inspection Visually inspecting fiber connectors at every stage of handling BEFORE mating them. Connectors are much easier to clean prior to mating, before embedding debris into the fiber.

Reactive Inspection Visually inspecting fiber connectors AFTER a problem is discovered, typically during troubleshooting. By this time, connectors and other equipment may have suffered permanent damage.
Fiber AFTER Mating and Numerous Cleanings
Inspection Acceptance Criteria
Zone Name
Defects
A. CORE (0–25μm)
B. CLADDING (25–115μm)
C. ADHESIVE (115–135μm)
D. CONTACT (135–250μm)
4 =< 3μm
No limit
None
No limit < 2μm 5 from 2–5 μm None > 5μm
None => 10μm
As seen in the table above, the “CORE” zone is the most critical. The core zone MUST be defect free.

Setting up the FiberChek Probe
The following video shows the basic probe setup.
Using the FiberChek Probe
Preferred method for testing is tip to mating adaptor to fiber
Attach the APC mating adaptor tip to the Scope
Connect a mating adaptor to the fiber
The following video shows the basic tip inspection
Screw the barrel (BAP1) to the probe finger tight
Screw the needed scope tip on the barrel finger tight
Verify that both connections are tight
Insert the scope into the mating adaptor

Focus the image and run the test
Installing Basic Scope Tips to the FiberChek Probe
The following videos show the p5000i as the FiberChek Probe uses the same tips.
Installing CFST Scope Tips to the FiberChek Probe
Unscrew the barrel (BAP1) from the Scope
Screw the CFST directly to the scope finger tight
The following videos show the p5000i, but the FiberChek Probe uses the same tips.
The following section will cover the various testing areas for fiber inspection.
Inspecting at the PFP
SC/APC MATING ADAPTOR tip for testing Patch Panels
SC/APC MATING ADAPTOR tip and a spare mating adaptor for testing fibers/connectors
Testing the PFP with the FiberChek Probe
The following video shows the basic tip installation
Preferred method for testing is tip to bulkhead to fiber
Attach the APC Bulkhead tip to the Scope
Inspecting the Tether Connector (Core technicians only)
Female Cable Adaptor
Male Cable Adaptor
Base Tip
Optitip Fiber Positions
Factory Splice
Terminal
Attach the Base Tip to the microscope.
For OptiTip tether cables, affix the appropriate adaptor (male, female) onto the Base Tip.
Insert the OptiTip plug into the scope Adaptor.
Use the panning knob to scroll left and right across each fiber and test as needed (up to 12 tests).
Inspecting OptiTap Terminals
Use Tip FBPT-COD-L for OptiTap fiber port
Note: The OptiTap tip does not use the barrel adaptor Please remove the barrel (BAP1) from the microscope
SC/APC tip for testing OptiTap drops
Testing the CFST with the FiberChek Probe
Attach the CFST tip to the Scope (no barrel)
Insert the scope into the CFST
Turn the Scope to align with the APC fiber
Attach the CSFT tip to the Scope (no barrel)
Insert the scope into the CSFT
Inspecting EVOLV Terminal (Pushlok)
EVOLV tip for testing the EVOLV port
Note: The EVLOV tip does not use the Barrel adaptor Please remove the barrel (BAP1) from the microscope
SC/APC tip for testing the Pushlock frop
NOTE – Testing the EVOLV terminal uses the same procedure as the OptiTap video in this training
Inspecting Drops
Inspecting the Premises
Optional -use tip FBPT-U25MA for SC/APC Fiber Tips
Don't Forget about the ONT
SC/APC MATING ADAPTOR tip for testing SFP ports
NOTE – an SFP and the ONT must be inspected and cleaned like the fibers. These get dirty too!!!!!
VIAVI Microscope Tips for Field Operations
Each testing location requires a specific tip.
Most tips require an extension barrel (pictured)
EVOLV and OptiTap tips do NOT use the barrel
