BlueOptics Lenovo AV24 Compatible BlueLAN Passive 100GBASE-CR4 QSFP28 to 4x25GBASE-CR SFP28 Direct Attach Breakout Cable, 5m, AWG26 (AV24-BL)

The BlueOptics AV24-BL is a high-performance passive Direct Attach Breakout Cable (DAC) designed for reliable 100 Gbps connectivity in data centers and high-performance networking environments. This cable converts a single QSFP28 port into four SFP28 ports, enabling cost-effective migration to higher speeds while leveraging existing 25 Gbps infrastructure.

Advantages

Ultra-low power consumption (passive design, no external power needed) and hot-swappable form factor ensure easy deployment and energy efficiency. The breakout configuration allows flexible network architecture, reducing the need for additional switches or transceivers.

Suitable for

• Data center interconnects
• High-performance computing clusters
• Server-to-switch connectivity
• Network upgrades from 25G to 100G

Key specifications
