Inspecting and
Cleaning Fiber Optic
Connections
Small amounts of microscopic dust or other contaminants can seriously impair or
disable a fiber optic network. To ensure that your network operates reliably, you
must carefully inspect and clean each connection when installing fiber optical
products.
Table B-1 lists some typical contaminants of a fiber optic connection. The
inspection and cleaning procedure begins on page 61.
Table B-1 Typical Contaminants
Contaminant Comments
Dust particle, 1 micron Can block up to 1% of the light transmission,
creating a loss of 0.05 dB
Dust particle, 9
microns
Although microscopic, the particle can
completely block the fiber core
Human hair Typically 50 to 75 microns in diameter
Oil Frequently caused by touching
Film residues Can accumulate from vapors or smoke
Powdery coatings Can be left behind after water or other solvents
