To remove the cable, follow these steps:
Step 1
Attach an ESD-preventive wrist strap and follow its instructions for use.
Step 2
Press the release latch on the cable, grasp the connector near the connection point, and gently pull the
connector from the transceiver.
Step 3
Insert a dust plug into the cable end of the transceiver.
Step 4
Insert a dust plug onto the end of the cable.
Maintaining SFP Transceivers and Fiber-Optic Cables
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 it
should be kept 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 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. This prevents fingerprints and other contamination of the
connectors.
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.
