Questions & Answers
Q
What is DWDM-SFP10G-4294-ER-C?
A
DWDM-SFP10G-4294-ER-C is a Cisco-compatible 10GBase-DWDM SFP+ transceiver module that operates at 1542.94 nm and supports link lengths up to 40 km over single-mode fiber.
Q
Which wavelength does the DWDM-SFP10G-4294-ER-C use?
A
The module uses a fixed DWDM wavelength of 1542.94 nm (ITU Channel 42) optimized for high-density wavelength division multiplexing.
Q
What is the maximum transmission distance of this 10GBase-DWDM SFP+?
A
This transceiver supports distances up to 40 km over standard single-mode fiber (SMF-28) with an optical link budget of approximately 19 dB.
Q
Is the DWDM-SFP10G-4294-ER-C compatible with Cisco hardware?
A
Yes, it is fully compatible with Cisco switches and routers that support 10GBase-DWDM SFP+ modules, including Catalyst and Nexus series.
Q
Which Cisco switch models support this DWDM SFP+ transceiver?
A
It is supported on Cisco Catalyst 2960-X, 3650, 3850, 4500E, and Nexus 5000/7000 platforms with SFP+ uplink slots.
Q
What fiber type and connector are required?
A
The module requires ITU-T G.652 single-mode fiber with an LC duplex connector for optimal 10GBase-DWDM performance.
Q
Does this SFP+ module support digital diagnostics (DDM)?
A
Yes, it includes digital diagnostics monitoring (DDM) compliant with SFF-8472 for real-time monitoring of optical power, temperature, and voltage.
Q
What is the operating temperature range?
A
The module operates reliably between 0 °C and 70 °C (Standard Operating Temperature) for data center and telecom environments.
Q
How much power does the DWDM-SFP10G-4294-ER-C consume?
A
Typical power consumption is less than 1.5 W, ensuring energy-efficient operation in high-density installations.
Q
How do I install the 10GBase-DWDM SFP+ module?
A
To install, power down the port, align the module with the SFP+ port, slide it in until it clicks, and then power the port back on for automatic detection.
Q
What maintenance is required for this DWDM module?
A
Regularly inspect and clean LC connectors with fiber-friendly tools and ensure proper fiber bend radius to maintain signal integrity.
Q
Can I mix CWDM and DWDM SFP+ modules in the same network?
A
Yes, but CWDM and DWDM channels must not overlap; ensure your DWDM wavelengths (e.g., 1542.94 nm) are distinct from any CWDM channels.
Q
How do I verify the module is working correctly?
A
Use your switch’s show interface transceiver command to view DDM parameters such as optical power, temperature, and module status.
Q
What are the typical use cases for this DWDM transceiver?
A
Ideal for metro, long-haul, and high-density data center interconnects requiring precise wavelength management over 40 km links.
Q
What is the difference between DWDM and CWDM modules?
A
DWDM uses tightly spaced wavelengths (100 GHz ITU grid) for high-capacity networks, while CWDM uses wider channel spacing for cost-effective shorter links.
Q
What warranty and support are provided?
A
The module includes a lifetime limited warranty and free technical support to ensure reliable integration with Cisco networks.
