This Lenovo 3m DAC breakout cable splits a single 40GbE QSFP+ port into four separate 10GbE SFP+ ports, enabling flexible network connections without extra transceivers. It's commonly used in data centers and server rooms to connect switches, routers, or servers requiring high bandwidth and efficient port utilization.

Built for IT professionals and network engineers, this cable helps simplify complex setups by consolidating multiple 10GbE links into a single higher-speed interface. Its direct attach copper design reduces latency and power consumption compared to fiber alternatives.

Key Features

• High-speed 40Gbps data transfer aggregated over four 10Gbps lanes
• 3-meter copper cable ensuring reliable signal integrity and low latency
• Breakout design allowing one QSFP+ port to connect to four SFP+ ports
• Plug-and-play compatibility with Lenovo and standard QSFP+/SFP+ equipment
• Durable construction for stable performance in dense rack environments

This cable is typically deployed in data centers where optimizing port density and simplifying cabling is critical. It offers a practical way to extend network capacity without adding expensive modules or increasing power draw.

Its role is especially valuable in high-performance computing clusters and enterprise networks where multiple 10GbE connections are needed but physical space or switch ports are limited.
