Fiber cleaning

Overview
This procedure describes the 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 fibre cables please observe the following
safety warnings:
DANGER
Never look into the end of an exposed fibre or plug-in
optical connectors as long as the optical source is switched
on. This applies particularly to the connections of the optical
plug-in units.
CAUTION
To avoid cable break ensure that the bending radius of
optical fibre cables is not less than 30 mm.
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).
