Lenovo 7Z57A03570

Overview

The Lenovo 7Z57A03570 is a 15-meter optical cable designed to deliver high-speed data transmission using OM4 multimode fiber. It supports 40G and 100G Ethernet connections, making it an essential component for linking network devices that require MPO connectivity. This cable is ideal for data centers and enterprise environments where reliable, low-latency connections are critical.

Each end of the cable features an MPO male connector, allowing direct connection to switches, routers, patch panels, or transceivers with MPO interfaces. Its round, black jacket ensures flexibility and ease of routing through dense cable trays, helping maintain organized and efficient network setups.

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.
