products.
Table 2-3 lists some typical contaminants of a fiber optic connection.
The inspection and cleaning procedure begins on page 21 .
Important Points
• Before you begin cleaning, always inspect the fiber connections.
• Inspect and clean both fiber ends every time you make a
connection.
• Keep a protective cap on unplugged fiber connectors.
• Do not touch the end of a fiber.
• Store unused protective caps in a clean resealable container, located
nearby for easy access.
• Do not reuse cleaning tissues or swabs.
• Do not allow alcohol or another wet cleaning agent to dry on a fiber
end.
Table 2-3. 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
