Lenovo 3M 100G QSFP28 to 4x25G SFP28 Breakout DAC Cable

The Lenovo 7Z57A03565 is a 3 meter passive direct attach copper cable that converts one 100 G QSFP28 port into four separate 25 G SFP28 links. By creating these four independent channels, the cable lets administrators use an existing 100 G switch or network adapter port to feed multiple 25 G devices without buying transceivers or optical modules.

Its copper design supports high bandwidth transfers across short distances inside or between adjacent racks. This makes the cable a practical choice for top-of-rack connections in cloud clusters, virtualization hosts, or high-performance computing nodes where every watt and every port count. Power draw is negligible because the cable is passive, and that helps control heat in dense environments.

Deployment is straightforward. Each end is male and ready to plug directly into compatible cages on Lenovo hardware such as ThinkSystem NE10032 and NE2572 switches or SR250 servers. Once seated, the assembly delivers up to 100 G of aggregate throughput with the low latency that copper links provide.

• Breakout cable that maps one 100 G QSFP28 port to four 25 G SFP28 ports
• 3 meter 9.84 foot length for in-rack or short inter-rack runs
• Passive direct attach copper construction requires no separate optics or power
• Ideal for Lenovo ThinkSystem NE10032, NE2572, and SR250 deployments
• Male-to-male connectors enable simple plug-and-play installation
