Electric-arc cleaning of optical-fiber endfaces

Area of Science:

• Optical Engineering
• Materials Science

Background:

• Optical fiber fusion splicing is critical for telecommunications.
• Effective cleaning of fiber endfaces is essential for splice integrity.
• Existing cleaning methods may have unintended consequences.

Purpose of the Study:

• To investigate the cleaning action of fusion-splicing device cleaning arcs.
• To identify potential damage to optical fiber endfaces caused by these arcs.
• To determine factors influencing endface damage during cleaning.

Main Methods:

• Utilized interferometric analysis to examine optical fiber endfaces.
• Compared endface conditions before and after exposure to cleaning arcs.
• Investigated two distinct optical-fiber fusion-splicing devices.

Main Results:

• One fusion-splicing device's cleaning arc caused measurable damage to optical fiber endfaces.
• Interferometric analysis clearly showed alterations in endface topography post-cleaning.
• The position of the optical fiber relative to the cleaning arc was identified as a probable cause of damage.

Conclusions:

• The cleaning arc of certain fusion-splicing devices can induce endface damage.
• Fiber positioning is a critical parameter to control during the cleaning process.
• Further optimization of cleaning arc parameters is necessary to prevent fiber endface degradation.
