Cleaning Optics
It is important to inspect and clean fiber-optic components before making a fiber-optic connection (for 
example, plugging a fiber-optic connector into a fiber-optic receptacle). Any contamination in the fiber 
connection can cause the optic component or the whole system to fail. Even microscopic dust particles, 
oil from human hands, film residues (condensed from vapors in the air), and powdery coatings (left after 
water or other solvents evaporate) can cause a variety of problems for optical connections.
