Key Features

  • 3 m cable length
  • QSFP28 network connector on end A
  • 4 x SFP28 network connectors on end B
  • Active optical cable construction
  • Fiber optic cable type
  • Lenovo manufacturer part number 7Z57A03551
  • Breakout topology for 100G to 4 x 25G links
  • Split one 100G uplink into four 25G connections using QSFP28 to 4 x SFP28 breakout
Move 100G traffic into four 25G paths without adding conversion hardware or excess cable bulk. Lenovo’s 3 m breakout active optical cable is designed for short-reach data center links where port density, airflow, and clean routing matter. The QSFP28 end connects to a 100G uplink, while the four SFP28 ends feed downstream switches or servers at 25G each. Active optical construction helps maintain signal integrity across the 3 m span while keeping the cable lighter and easier to route than copper alternatives. That matters in crowded racks where bend management and front-to-back airflow can affect serviceability. For teams standardizing on 25G access with 100G aggregation, this cable supports a direct breakout topology that reduces the need for separate transceivers and patch assemblies. Use it where short, deterministic interconnects are preferred: top-of-rack to leaf switch, spine-to-leaf breakout, or server fan-out in high-density environments. It is a practical choice when you need predictable lane mapping, reduced cabling complexity, and a Lenovo-qualified path for mixed-speed Ethernet deployment.

Ideal For

  • Top-of-rack switch uplink breakout to four 25G server or switch ports
  • Leaf-spine aggregation where one 100G port must feed multiple 25G endpoints
  • Short-reach rack interconnects in dense enterprise data centers
  • Network refresh projects standardizing on 25G access and 100G aggregation
