Preparation
Clean the connector on the fiber cable before inserting it into the transceiver to prevent the
transfer of small particles and contaminants to the transceiver. If you switch an SFP, SFP+,
CSFP, CFP, or QSFP+ from one port to another ensure that you clean the fiber connectors
before reinserting them.
Apply high standards when inspecting and cleaning fiber connectors. Use a “dry” cleaning
method to clean fiber connectors.To clean the connector, you can either:
• Wipe the side and end of the ferrule with a lint-free alcohol-dampened cloth.
• Blow dry the ferrule with compressed air and inspect for lint. Do not insert the
compressed air nozzle into the receptacle.
Locking Mechanisms
SFP, SFP+, CSFP, CFP, and QSFP+ transceivers use different lock and release methods.
Possible lock and release mechanisms include:
• Bail— A bar or wire in the front of the transceiver that you use to release the module.
SFP, SFP+, and CSFP transceivers use bail-actuated bottom latching. QSFP+ use
bail-actuated side latching.
• Captive screws—Fixed screws on both sides of the transceivers. Screws are used on
CFP transceivers.
