Lenovo 7Z57A03573

Overview

The Lenovo 7Z57A03573 is a fiber optic network cable designed to convert a single MPO interface into four LC connectors, enabling efficient data distribution within data center racks. Measuring one meter in length and built with OM4 multimode fiber, it supports high-bandwidth connections by breaking out a 40 Gb Ethernet port into four 10 Gb Ethernet links. This cable is ideal for short-distance, high-speed networking needs where maintaining signal quality and minimizing latency are critical.

Key features

• Breakout design that simplifies connecting one MPO port to four LC ports, increasing network port density without extra hardware
• OM4 multimode fiber core that supports high-bandwidth data transfer over short distances, suitable for 40 GbE to 10 GbE link conversions
• One meter length optimized for intra-rack or row connections, reducing cable clutter and signal loss
• Factory-terminated male MPO and LC connectors for straightforward plug-and-play installation with QSFP+ and SFP+ transceivers
• Round cable jacket designed to handle typical bends and routing through overhead trays or under-floor ducts without compromising performance
• Compatibility with Lenovo networking equipment as well as any devices adhering to MPO and LC standards, ensuring flexible integration

Key specs

• Cable type: OM4 multimode fiber optic
• Length: 1 meter
• Connector types: 1 male MPO to 4 male LC
• Supported data rates: 40 Gb Ethernet breakout to four 10 Gb Ethernet links
• Fiber mode: Multimode

Connectivity and compatibility

This cable connects directly to QSFP+ transceivers via the MPO connector and to SFP+ ports through the four LC connectors, making it a practical choice for data centers upgrading or expanding their 40 GbE infrastructure. Its adherence to MPO and LC standards ensures it works seamlessly with a wide range of networking devices beyond Lenovo’s own switches, servers, and storage systems.

Ideal uses and environments

The Lenovo 7Z57A03573 fits well in data center environments where space and cable management are priorities. It is particularly useful for network engineers who need to increase port density within racks without adding patch panels or extra hardware. This cable supports short-range, high-speed connections, making it a strong choice for intra-rack or row-level fiber optic breakout applications.

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.
