Lenovo 1M 100G QSFP28 to QSFP28 Passive Copper Cable

The Lenovo 7Z57A03561 is a cable that uses direct attach copper and terminates with QSFP28 connectors on both ends, enabling 100 gigabit per second links across a one meter distance.

Because it is passive, the assembly consumes no power and introduces almost no latency, making it a straightforward and cost effective option when two devices sit close together inside the same rack or a neighboring cabinet.

Typical deployments include connecting a top of rack switch to Lenovo servers, linking storage controllers to high bandwidth network infrastructure, or joining nodes in a high performance computing cluster. Installers can simply plug in the cable and bring a 100G connection online without transceivers, patch panels, or airflow concerns.

The female to female interface follows the 4 pin Mini Din layout specified for QSFP28 ports, so the cable locks securely into enterprise network hardware from Lenovo as well as other vendors that honor the same standard.

Highlights:

• 100 Gbps throughput over a one meter span
• QSFP28 to QSFP28 passive copper construction
• Female to female 4 pin Mini Din connectors
• Works with enterprise network switches, servers, and storage systems
• No external power or active circuitry required
