Cisco Systems N3KC3064TQ10GT Manual De Usuario

QSFP+, SFP+, and SFP transceivers and fiber-optic cables must be kept clean and dust-free to maintain 
high signal accuracy and prevent damage to the connectors. Attenuation (loss of light) is increased by 
contamination and should be below 0.35 dB.

Consider the following maintenance guidelines:

Optical transceivers are static sensitive. To prevent ESD damage, wear an ESD-preventive wrist 
strap that is connected to the chassis. 

Do not remove and insert a transceiver more often than is necessary. Repeated removals and 
insertions can shorten its useful life. 

Keep all optical connections covered when not in use. If they become dusty, clean before using to 
prevent dust from scratching the fiber-optic cable ends.

Do not touch ends of connectors to prevent fingerprints and other contamination.

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 fiber-optic connection cleaning procedure.

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.
