To remove the cable, follow these steps:
Attach an ESD-preventive wrist strap and follow its instructions for use.

connector from the transceiver.
Insert a dust plug into the cable end of the transceiver.
Step 3
Insert a dust plug onto the end of the cable.

Maintaining SFP+ Transceivers and Cables

SFP+ transceivers 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.

SFP+ 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.
