Maintaining SFP Transceivers and Fiber-Optic Cables
• Clean regularly; the required frequency of cleaning depends upon the environment. In addition, clean
connectors if they are exposed to dust or accidentally touched. Both wet and dry cleaning techniques
can be effective; refer to your site's fibre-optic connection cleaning procedures.
• Inspect routinely for dust and damage. If damage is suspected, clean and then inspect fiber ends under
a microscope to determine if damage has occurred.
