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
should be below 0.35 dB.
Consider the following maintenance guidelines:

SFP transceivers are static sensitive. To prevent ESD damage, wear an ESD wrist strap that is
connected to the chassis.
Do not remove and insert a transceiver more often than is necessary. Repeated removals and
installation 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 fiber-optic cleaning procedures for your site.
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.
