Dust is the most common dirt in optical fiber connectors. The dust particles that
can be seen only by a microscope can affect the quality of optical signals,
deteriorate the system performance, and cause instability in network operation.
A 1-micrometer dust particle on the single-mode fiber 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 fiber core. Therefore, small dirt even that
cannot be seen by human eyes should be removed.
