Connecting to the Network
• Keep all optical connections covered when not in use. Clean them before using to prevent dust from
scratching the fiber-optic cable ends.
• Do not touch the ends of connectors. Touching the ends can leave fingerprints and cause other
contamination.
• Clean the connectors 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 fiber-optic connection cleaning procedures.
• Inspect routinely for dust and damage. If you suspect damage, clean and then inspect fiber ends under
a microscope to determine if damage has occurred.
