Fiber cleaning
...................................................................................................................................................................................................................................
Overview
This procedure describes the Alcatel-Lucent recommended method for the cleaning and
inspection of optical connectors using specific tools and materials that have been
proven to be effective in the assembly and testing of optical transmission equipment. It
is critical that the connector endfaces are clean and free from particular contamination
to assure proper performance and reliability of lightwave systems. With the modern
high-speed, high-power and wider bandwidth optical transmission systems, clean
connectors along the optical path are absolutely essential for successful operation.
Before working with optical fiber cables please observe the following safety warnings:
DANGER
Laser hazard
Never look into the end of an exposed fiber or plug-in optical connectors as long as
the optical source is switched on.
CAUTION
Cable break
To avoid cable break ensure that the bending radius of optical fiber cables is not less
than 38 mm [1.5 inches] or 20 times the diameter of the cable (whichever is greater).
Cleaning of optical connectors
Optical connectors are only to be cleaned in accordance with the cleaning instructions
listed below.
If impurities are assumed, the use of a fiberscope is recommended in order to check
the connector face for impurities (e.g. fluff, dust particles). A fiberscope with a
magnification x 200 is preferred.
Connectors
If impurities are discovered, the optical connector must be cleaned in accordance with
the following rules:
...................................................................................................................................................................................................
1
Wipe off the connector face lengthwise (not with a circular motion.) using a smooth
tissue (moistened with isopropanol).

2
Wipe off the connector face lengthwise (not with a circular motion.) using a dry and
smooth tissue.
