Image Tab - Fluke FiberInspector Pro FI-3000 User Manual

Image Tab

On the IMAGE tab, you can view the particles, scratches, and other defects.
Tap the image to see or hide the overlay that shows the yellow zone rings and
the green (PASS) or red (FAIL) highlighted defects.
Pass/Fail Highlights:
• Red: FAIL. The scratch or defect is larger than the maximum size that
the limit allows, is closer to the fiber core than the limit allows, or
there are more scratches or defects than the limit allows.
• Green: PASS. The limit allows the scratch or defect because it is too
small or too far from the core to cause problems, or there are fewer
than the maximum allowed number of scratches or defects of that size.
If a defect is possibly a dirt particle, clean the endface and do the
inspection again. You must remove all loose particles because they
can move into the core when you make connections.
Rings: On single fiber endfaces, the rings identify the core, cladding,
adhesive, and contact zones. On MPO endfaces, the rings identify the core
and cladding zones.
• The Core zone is the optical fiber. This area typically has a diameter of
9 μm for singlemode fiber or 50 μm or 62.5 μm for multimode fiber.
• The Cladding zone is the area between the outer yellow ring and the
Core zone. The cladding is a layer of reflective material around the
core that keeps the optical signal in the core.
• The Adhesive zone is the ring of epoxy or glue that attaches the
cladding to the ferrule. This is the zone between the two green rings
on the FiberInspector image. The middle of this area has a diameter of
125 μm, which is the diameter of the ferrule. Standards for endface
analysis do not specify limits for scratches or defects in the adhesive
zone, so defects and scratches in this area do not affect the PASS/FAIL
result.
• The Contact zone is the area on the ferrule that touches the other fiber
when you make a connection. The blue ring around the Contact zone
has a diameter of 250 μm for all limits.
