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.

Follow these maintenance guidelines:

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.
