Lenovo 4Z57A10852

Overview

The Lenovo 4Z57A10852 is a 30-meter fibre optic cable designed for high-speed data transmission in multimode network environments. It uses the OM4 standard, which supports low attenuation and high bandwidth, making it suitable for demanding 40G and 100G Ethernet applications. Equipped with LC connectors on both ends, this cable ensures precise alignment and reliable connections in data centres and enterprise backbones.

Key features

• OM4 multimode fibre provides enhanced bandwidth and reduced signal loss for consistent high-speed performance.
• LC connectors feature a small form factor that supports high-density port layouts, optimizing space in crowded racks.
• 30-meter length is ideal for typical rack-to-rack connections without excess slack, aiding in neat cable management.
• Designed to support 40G and 100G Ethernet deployments, meeting the needs of modern network infrastructures.
• Durable construction ensures reliable links in data centres, telecommunications rooms, and enterprise backbones.

Connectivity and compatibility

This fibre optic cable is compatible with network equipment that supports LC connectors and OM4 multimode fibre. It fits well in environments requiring high-density connections, such as switch-to-switch links within racks or between adjacent racks. The cable’s design supports seamless integration into existing fibre patching systems and aggregation paths.

Ideal uses and environments

The cable is well suited to data centres and enterprise telecommunications rooms where reliable, high-bandwidth connections are essential. It works effectively for linking network switches, servers, and storage devices over short to medium distances. Its length and connector type make it a strong choice for structured cabling in high-density network setups where space and performance are priorities.

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.
