Installing SFP+ and SFP Optical Cables
To prevent damage to an optical cable and transceiver, disconnect cables before installing or removing
transceivers. Note
Step 1 Attach an ESD-preventive wrist strap and follow its instructions for use.
Step 2
Remove the dust cover from the connector on the cable.
Step 3 Remove the dust cover from the cable end of the transceiver.
Step 4
Align the cable connector with the transceiver and insert the connector into the transceiver until it clicks into place.
If the cable does not install easily, ensure that it is correctly positioned before continuing. Caution
If you cannot install the cable into the transceiver, insert or leave the dust plug in the cable end of the transceiver. Note
For instructions on verifying connectivity, see the appropriate Cisco Nexus Series configuration guide.
Maintaining Transceivers and Optical Cables
Transceivers and fiber-optic cables must be kept clean and dust free to maintain high signal accuracy and
prevent damage to the connectors. Contamination increases attenuation (loss of light) and should be below
0.35 dB.
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.
