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.
Consider the following 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 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.

Removing and Installing SFP Transceivers

Caution Excessively removing and installing an SFP transceiver can shorten its life. Do not remove and insert
SFP transceivers more often unless it is absolutely necessary. Cisco recommends disconnecting cables
before installing or removing SFP transceivers to prevent damage to the cable or transceiver.
This section describes the proper method for installing and removing an SFP transceiver.

Installing an SFP Transceiver

To install an SFP transceiver, follow these steps:
Step 1 Attach an ESD-preventive wrist strap and follow its instructions for use.
