Lenovo 7Z57A03546

Overview

The Lenovo 7Z57A03546 is a QSFP28 active optical cable designed to deliver 100 Gigabit Ethernet connectivity over a fixed length of 3 meters. It integrates QSFP28 transceivers at both ends, enabling a direct attach connection between compatible networking devices without the need for separate optical modules. This cable is ideal for data centers and enterprise networks that require high-bandwidth, low-latency links between switches, servers, or storage systems within short distances.

Key features

• Integrated QSFP28 transceivers simplify installation with plug and play setup, eliminating the need for separate optical modules.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
