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.
The module uses a fixed DWDM wavelength of 1542.94 nm (ITU Channel 42) optimized for high-density wavelength division multiplexing.
This transceiver supports distances up to 40 km over standard single-mode fiber (SMF-28) with an optical link budget of approximately 19 dB.
Yes, it is fully compatible with Cisco switches and routers that support 10GBase-DWDM SFP+ modules, including Catalyst and Nexus series.
It is supported on Cisco Catalyst 2960-X, 3650, 3850, 4500E, and Nexus 5000/7000 platforms with SFP+ uplink slots.
The module requires ITU-T G.652 single-mode fiber with an LC duplex connector for optimal 10GBase-DWDM performance.
Yes, it includes digital diagnostics monitoring (DDM) compliant with SFF-8472 for real-time monitoring of optical power, temperature, and voltage.
The module operates reliably between 0 °C and 70 °C (Standard Operating Temperature) for data center and telecom environments.
Typical power consumption is less than 1.5 W, ensuring energy-efficient operation in high-density installations.
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.
Regularly inspect and clean LC connectors with fiber-friendly tools and ensure proper fiber bend radius to maintain signal integrity.
Yes, but CWDM and DWDM channels must not overlap; ensure your DWDM wavelengths (e.g., 1542.94 nm) are distinct from any CWDM channels.
Use your switch’s show interface transceiver command to view DDM parameters such as optical power, temperature, and module status.
Ideal for metro, long-haul, and high-density data center interconnects requiring precise wavelength management over 40 km links.
DWDM uses tightly spaced wavelengths (100 GHz ITU grid) for high-capacity networks, while CWDM uses wider channel spacing for cost-effective shorter links.
The module includes a lifetime limited warranty and free technical support to ensure reliable integration with Cisco networks.
