Maintaining Transceivers and Optical Cables

Consider the following maintenance guidelines:

• Transceivers are static sensitive. To prevent ESD damage, wear an ESD-preventative wrist strap that is

connected to the grounded 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. Clean them before using to prevent dust from

scratching the fiber-optic cable ends.

• Do not touch the ends of connectors. Touching the ends can leave fingerprints and cause other

contamination.

• Clean the connectors 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 the fiber-optic connection cleaning procedures for your site.

• Inspect routinely for dust and damage. If you suspect damage, clean and then inspect fiber ends under a

microscope to determine if damage has occurred.
