Note
Replace Faulty SFP, SFP+, or XFP Connectors
Small Form-factor Pluggable (SFP), Enhanced Small Form-factor Pluggable (SFP+), and 10-Gbps SFP (called
XFP) modules are input/output devices that plug into some DWDM cards to link the port with the fiber-optic
network. The type of SFP, SFP+, or XFP determines the maximum distance that traffic can travel from the
card to the next network device. For a description of SFP, SFP+, and XFP modules and their capabilities,
refer to the Installing the GBIC, SFP, SFP+, and XFP Optical Modules in Cisco ONS Platforms. SFP, SFP+,
and XFP modules are hot-swappable and can be installed or removed while the card or shelf assembly is
powered and running.
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams
or view directly with optical instruments. Statement 1051.
