Lenovo 7Z57A03573 3M Network Cable

The Lenovo 7Z57A03573 is a fiber optic network cable that measures one meter in length and converts a single MPO interface into four LC connectors. Built with OM4 multimode fiber, it moves large amounts of data over short distances, a common need when breaking out a 40 Gb Ethernet port to four 10 Gb Ethernet links inside a data center rack.

Installation is straightforward. The male MPO side plugs into a QSFP+ transceiver, while the four male LC ends slot directly into SFP+ ports. This plug-and-play approach lets network engineers increase port density without adding patch panels or extra hardware, keeping latency low and cable paths simple.

The round jacket handles typical bends through overhead trays or under-floor ducts, and the OM4 core maintains signal quality within standard multimode reach limits. As a genuine Lenovo component, the cable pairs naturally with Lenovo switches, servers, and storage systems, yet it remains fully compatible with any equipment that follows the same MPO and LC standards.

• Breakout design that provides one MPO connector and four LC connectors
• OM4 multimode fiber supporting high-bandwidth links between 40 GbE and 10 GbE devices at short range
• One meter total length, well suited for connections within the same rack or row
• Factory-terminated male connectors for simple plug and play integration
• Round cable jacket that routes cleanly through standard trays and ducts
