Lenovo 7Z57A03573 3M Network Cable

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

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.
