Q
What is a Cisco XFP module?
A
A Cisco XFP (10-Gigabit Small Form-Factor Pluggable) module is a hot-swappable transceiver designed for 10 Gbps optical or copper networking applications in Cisco switches and routers.
Q
What data rates do Cisco XFP modules support?
A
Cisco XFP modules support line rates up to 10 Gbps, enabling high-speed connectivity for enterprise and service-provider networks.
Q
What is the maximum reach of a Cisco XFP module?
A
Depending on the model and fiber type, Cisco XFP modules support distances from 300 m on multi-mode fiber to 80 km on single-mode DWDM fiber.
Q
Are Cisco XFP modules hot-swappable?
A
Yes. Cisco XFP modules are hot-swappable, allowing installation or removal without powering down the host device.
Q
Which connector types do Cisco XFP modules support?
A
Cisco XFP modules support LC connectors for fiber and RJ-45 for copper, depending on the transceiver variant.
Q
How do I choose the right Cisco XFP module for my network?
A
Select a Cisco XFP module based on required data rate (10 Gbps), fiber type (single-mode or multi-mode), reach, connector type, and wavelength to match your network design.
Q
Can I use third-party XFP modules in Cisco equipment?
A
Cisco recommends using Cisco-branded XFP modules to ensure compatibility, support, and warranty coverage; third-party modules may work but can void support agreements.
Q
How do I install a Cisco XFP module?
A
Power off the interface (if required), slide the Cisco XFP module into the port until it clicks, and then enable or power on the interface in the CLI or GUI.
Q
How can I verify that my Cisco device recognizes the XFP module?
A
Use the command “show interfaces transceiver details” in the Cisco IOS CLI to display model, serial number, wavelength, and status of the installed XFP module.
Q
What is the difference between Cisco XFP and SFP+ modules?
A
Cisco XFP modules have an external electrical interface and higher power budget, whereas SFP+ integrates clock data recovery and has a smaller form factor with lower power consumption.
Q
Are Cisco XFP modules MSA-compliant?
A
Yes. Cisco XFP modules comply with the XFP Multi-Source Agreement (MSA), ensuring interoperability across MSA-compliant devices.
Q
What wavelengths are available in Cisco XFP modules?
A
Cisco XFP modules are available in standard wavelengths such as 850 nm, 1310 nm, 1550 nm, and DWDM channels ranging from 1528.77 nm to 1563.86 nm.
Q
How do I troubleshoot a link failure with a Cisco XFP module?
A
Check the system logs and interface counters with “show interfaces” and “show interfaces transceiver details,” verify fiber cleanliness, and confirm matching transmit/receive wavelengths.
Q
Can Cisco XFP modules be used in DWDM networks?
A
Yes. Cisco offers DWDM-tuned XFP modules with precise ITU-grid wavelengths for integration into DWDM transport systems.
Q
How do I maintain and clean Cisco XFP module connectors?
A
Use an approved fiber-optic cleaning kit to gently remove dust and contaminants from the LC or RJ-45 connector before each insertion to maintain optimal signal integrity.
