Maintaining SFP+ and QSFP+ Transceivers and Fiber-Optic
Cables
SFP+ and QSFP+ 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.
Follow these maintenance guidelines:
• SFP+ and QSFP+ 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.
