Is It Clean?

Dirt is everywhere, and a typical dust particle (2–15 μm in diameter) can significantly
affect signal performance and cause permanent damage to the fiber end face. Most
field test failures can be attributed to dirty connectors, and most connectors are not inspected until the problem is
detected, after permanent damage has already occurred.
ZONES AND ACCEPTANCE CRITERIA
Zones are a series of concentric circles that identify areas of interest on the connector end face. The inner-most
zones are more sensitive to contamination than the outer zones.
Acceptance criteria are a series of failure thresholds that define contamination limits for each zone.
gRADINg PROCESS
1.
Count/measure the particles/contamination that are on the fiber surface.
2.
Estimate or use a grading overlay to grade the fiber by determining the number and size of each particle
that are present in each of the 4 fiber zones.
*Note: In most cases, there are no limits to the number/size of
contamination present on Zone C (Adhesive/Epoxy).
 If acceptable, do not touch it and CONNECT.
 If not acceptable, CLEAN.
