Warranty on 400G Pluggable Optical Module

Warranty coverage for 400G optical modules varies by vendor, ranging from 5-year limited warranties for OEM modules like Cisco to lifetime warranties for certain third-party suppliers such as Carritech Optics and FS.

OEM Vendor Warranties

Cisco offers a 5-year limited hardware warranty on its 400G pluggable modules, including the QDD400G family, effective from September 7, 2020. This warranty covers hardware defects and is an extension from the previous 1-year or 90-day limited warranties. Products purchased before this date are covered under the warranty terms in effect at the time of purchase.

Arista and other major OEMs typically provide standard limited warranties on their 400G transceivers, often ranging from 1 to 5 years depending on the product line and purchase agreement. Users should consult the specific datasheets or warranty bulletins for exact coverage.

Third-

Party Vendor Warranties

Carritech Optics provides a lifetime warranty on all 400G optical transceivers, including QSFP-DD modules. Their warranty ensures long-term durability and consistent performance, with rigorous quality control and compatibility testing for major OEM platforms such as Cisco, Juniper, Arista, Huawei, Nokia, and Dell.

F

S also offers a lifetime warranty on its 200G/400G coherent CFP2 optical transceivers, along with 100% testing and a 30-day free return policy, providing additional assurance for enterprise deployments.

Key Considerations

Compatibility: Third-party modules with lifetime warranties are generally tested for interoperability with major OEM platforms, ensuring safe deployment without voiding OEM equipment warranties. Warranty Scope: Lifetime warranties typically cover manufacturing defects and module failures under normal operating conditions, but may exclude damage from misuse, improper installation, or environmental factors. Deployment Confidence: Choosing modules with extended or lifetime warranties can reduce replacement costs and downtime, especially in high-density 400G network environments.

In summary, OEM 400G modules like Cisco's QDD400G come with a 5-year limited warranty, while reputable third-party suppliers such as Carritech Optics and FS offer lifetime warranties, providing flexibility and long-term assurance for network operators.
