4.1.4.5 Inspecting and Cleaning Optical Fiber Connectors and Adapters
4.1.4.5.1 Overview
This topic introduces the purpose and procedure of cleaning optical ber
connectors, as well as polluters to optical ber connectors.
Cleaning ber connectors is to remove dust or other dirt to avoid performance
degradation of optical transmission systems.
Figure 4-36 shows an optical
ber connector.

Optical ber connectors should be free of:
● Dust
● Grease (usually brought by hands)
● Condensate residue
● Powder (evaporated residue of water or solvent)
Dust is the most common dirt in optical
ber connectors. The dust particles that
can be seen only by a microscope can aect the quality of optical signals,
deteriorate the system performance, and cause instability in network operation.
A 1-micrometer dust particle on the single-mode
ber connector can block 1%
light and cause 0.05 dB attenuation. A 9-micrometer dust particle that cannot be
seen by human eyes can block an entire
ber core. Therefore, small dirt even that
cannot be seen by human eyes should be removed.
