Q
What is a Cisco ONS compatible SFP+ DWDM transceiver?
A
A Cisco ONS compatible SFP+ DWDM transceiver is a hot-swappable optical module that enables 10 Gbps Dense Wavelength Division Multiplexing on Cisco Optical Network Systems. It operates on ITU-T grid wavelengths and integrates seamlessly into DWDM networks.
Q
Which data rates and protocols does this module support?
A
The module supports up to 10 Gbps data rate and is compatible with Fibre Channel, Ethernet (10GBASE-ER), SONET/SDH, and OTU2/OTU2e protocols over a single wavelength.
Q
What wavelength grid and channel spacing are supported?
A
It supports ITU-T DWDM grid channels from 1528.77 nm to 1563.86 nm with 100 GHz channel spacing, ensuring compatibility with industry-standard DWDM systems.
Q
How far can a Cisco ONS compatible SFP+ DWDM transceiver transmit?
A
Reach varies by wavelength and fiber type but typically extends up to 80 km over single-mode fiber without amplification. Extended-reach versions can reach up to 120 km with EDFAs.
Q
What fiber type and connector are required?
A
The transceiver requires ITU-G.652 single-mode fiber and uses an LC duplex connector for low-loss, high-density connections in DWDM networks.
Q
Is the SFP+ DWDM transceiver hot-swappable?
A
Yes. The module is hot-swappable, allowing insertion or removal without powering down the Cisco ONS platform, minimizing network downtime.
Q
Does it support Digital Diagnostic Monitoring (DDM)?
A
Yes. It offers DDM (per SFF-8472) for real-time monitoring of optical output/input power, temperature, laser bias current, and supply voltage via the host platform.
Q
Which Cisco ONS platforms are compatible?
A
Compatibility includes Cisco ONS 15454 series, ONS 15454-E, and ONS 15454 MSTP systems. Always verify firmware requirements before deployment.
Q
Can it interoperate with non-Cisco DWDM mux/demux?
A
Yes. It adheres to ITU-T standards, enabling interoperability with any vendor’s DWDM mux/demux equipment as long as wavelength and channel spacing match.
Q
What is the typical power budget of this transceiver?
A
The typical optical power budget is between 0 dB to +4 dB, depending on the wavelength and transmit power class (Class 1 laser). Check the datasheet for exact values.
Q
Are third-party Cisco ONS compatible SFP+ modules certified?
A
Quality-assured third-party modules undergo multi-stage testing and certification to ensure 100% Cisco platform compatibility, CE/FCC compliance, and IEC safety standards.
Q
How do I install a Cisco ONS compatible SFP+ DWDM module?
A
Power off the port, align the LC connector, insert the module into the SFP+ slot until it clicks, power on the port, and verify via the CLI or GUI that the module is recognized.
Q
How do I monitor the performance of the SFP+ DWDM transceiver?
A
Use Cisco IOS commands (show interface transceiver details) or the NMS to read DDM parameters such as optical power, temperature, and supply voltage for proactive management.
Q
What warranty and support options are available?
A
Most vendors offer a limited lifetime warranty, 24/7 technical support, and advanced replacement services to ensure continuous DWDM network operation.
Q
Can I mix OEM and third-party SFP+ DWDM modules in the same system?
A
Yes. As long as all modules adhere to ITU-T specifications and your Cisco platform’s firmware supports them, you can mix OEM and certified third-party transceivers.
Q
How do I select the correct part number or wavelength?
A
Identify the required ITU channel (e.g., C17 for 1553.33 nm), then order using your vendor’s part number (e.g., XFP-DWDM-C17) aligned to the Cisco ONS compatibility list.
Q
What cost savings can I expect with third-party compatible modules?
A
Third-party modules typically cost 40–60% less than OEM parts without compromising performance or warranty, offering significant savings for large-scale DWDM deployments.
