Fiber Cleaning Introduction
Warning:
Before attempting to clean or inspect fiber optics it is strongly recommended that the technician
have a good understanding of the IEC 61300-3-35 fiber optics standard procedure. This document can be
obtained simply by performing an internet search for IEC 61300-3-35.
It is important that every fiber connector be inspected and cleaned prior to mating. This document describes
inspection and cleaning processes for fiber optic connections. The procedures in this document describe basic
inspection techniques and processes of cleaning for fiber optic cables, bulkheads, and adapters used in fiber
Optics connections.
Note:
This document is intended for use by service personnel, field service technicians, and hardware
installers.
Inspection and Cleaning are Critical
Clean fiber optic components are a requirement for
quality connections between fiber optic equipment.
One of the most basic and important procedures for the
maintenance of fiber optic systems is to clean the fiber
optic equipment.
Any contamination in the fiber connection can cause failure of the component or failure of the whole system.
Even microscopic dust particles can cause a variety of problems for optical connections. A particle that
partially or completely blocks the core generates strong back reflections, which can cause instability in the
laser system. Dust particles trapped between two fiber faces can scratch the glass surfaces. Even if a particle is
only situated on the cladding or the edge of the end face, it can cause an air gap or misalignment between the
fiber cores which significantly degrades the optical signal.
In addition to dust, other types of contamination must also be cleaned off the end face. Such materials
include:
•
Oils, frequently from human hands
•
Film residues, condensed from vapors in the air
•
Powdery coatings, left after water or other solvents evaporate away
These contaminants can be more difficult to remove than dust particles and can also cause damage to
equipment if not removed. When you clean fiber components, always complete the steps in the procedures
carefully. The goal is to eliminate any dust or contamination and to provide a clean environment for the fiber
optic connection. Remember that inspection, cleaning and re-inspection are critical steps which must be done
before you make any fiber-optic connection.
General Reminders and Warnings
Review these reminders and warnings before you inspect and clean your fiber-optic connections.
Reminders:
•
Always turn off any laser sources before you inspect fiber connectors, optical components or
bulkheads.
•
Always make sure that the cable is disconnected at both ends.
•
Always wear the appropriate safety glasses when required in your area.
•
Always inspect the connectors or adapters before you clean.
•
Always inspect and clean the connectors before you make a connection.
•
Always use the connector housing to plug or unplug a fiber connector.
