Q
What is a Cisco Compatible SFP SONET module?
A
A Cisco Compatible SFP SONET module is a small form-factor pluggable transceiver designed to provide reliable SONET/SDH connectivity in Cisco routers and switches, fully interoperable with Cisco IOS and hardware.
Q
Which SONET and SDH rates are supported by these SFPs?
A
These SFP SONET modules support standard OC-3 (155 Mbps), OC-12 (622 Mbps), OC-48 (2.5 Gbps), STM-1, STM-4 and STM-16 rates, ensuring flexible bandwidth options for diverse network needs.
Q
Are Cisco Compatible SFP SONET modules fully interoperable with Cisco devices?
A
Yes. These third-party SFP SONET modules are Cisco IOS-compliant and pass Cisco’s hardware compatibility checks, delivering plug-and-play functionality without requiring configuration hacks or additional coding.
Q
How do I install a Cisco Compatible SFP SONET module?
A
Power down the target Cisco device, insert the SFP SONET module into the SFP port until it clicks, then power up. The device auto-negotiates and recognizes the module within seconds.
Q
What link distances can I achieve with these SFP SONET modules?
A
Link distances vary by wavelength and fiber type. Typical ranges are up to 40 km over single-mode fiber at 1310 nm and up to 10 km at 850 nm on multimode fiber.
Q
Which fiber types and wavelengths are supported?
A
Supported fiber types include single-mode and multimode. Wavelength options range from 850 nm for short-range multimode links to 1310 nm and 1550 nm for longer single-mode distances.
Q
Do these modules support digital optical monitoring (DOM)?
A
Yes. Cisco Compatible SFP SONET modules with DOM provide real-time monitoring of optical power, temperature, voltage and transmit/receive bias current via standard I2C interfaces.
Q
Are Cisco Compatible SFP SONET modules MSA-compliant?
A
All Cisco Compatible SFP SONET modules adhere to the IEEE Multi-Source Agreement (MSA) standard, ensuring mechanical and electrical compatibility across network hardware.
Q
What operating temperature ranges do they support?
A
Standard Cisco Compatible SFP SONET modules operate between 0 °C and 70 °C. Industrial-grade variants extend the range from -40 °C to 85 °C for harsh environments.
Q
How do I verify compatibility with my Cisco device?
A
Check the Cisco hardware compatibility matrix or use the CLI command 'show inventory' after inserting the module. Supported modules will appear with correct part numbers and no error messages.
Q
Can I mix Cisco Compatible and Cisco-branded SFP SONET modules in the same device?
A
Yes. You can mix third-party Cisco Compatible and OEM modules, provided all modules share compatible data rates and protocols. The device will recognize them equally.
Q
What are the typical use cases for Cisco Compatible SFP SONET modules?
A
Common use cases include metropolitan SONET rings, long-haul backbone links, carrier Ethernet interconnects and legacy TDM to packet network migration in enterprise and service provider environments.
Q
Do these modules come with a warranty and technical support?
A
Cisco Compatible SFP SONET modules typically include a one-year limited warranty and access to vendor technical support for troubleshooting, replacement and firmware updates.
Q
How can I troubleshoot a link failure with these SFP SONET modules?
A
Verify fiber cleanliness, check DOM readings for out-of-range power levels, ensure correct wavelength pairing, and confirm the host port configuration matches the module’s SONET rate.
Q
Are software upgrades or special drivers required for installation?
A
No. These modules are fully Cisco IOS-compliant and require no special drivers or firmware updates. The host platform recognizes them automatically upon insertion.
Q
What should I consider when selecting a Cisco Compatible SFP SONET module?
A
Key factors include required data rate, link distance, fiber type, operating temperature range and the need for DOM. Match module specs to your network’s performance and environmental requirements.
