BlueLAN CAB-Q-4S-100G-2M-BL Compatible Arista Passive 100GBASE-CR4 QSFP28 to 4x25GBASE-CR SFP28 Direct Attach Breakout Cable, 2m, AWG26

The BlueLAN CAB-Q-4S-100G-2M-BL is a high-performance passive Direct Attach Copper (DAC) breakout cable designed for compatibility with Arista networking equipment. It provides a cost-effective and reliable solution for high-speed data center interconnects, enabling seamless migration from 100G to 25G infrastructure.

Advantages

This breakout cable offers significant advantages over traditional optical transceivers and fiber cabling. It consumes zero power, reducing overall energy costs and heat dissipation. The passive design ensures low latency and high reliability, while the integrated QSFP28 to 4x SFP28 connectors eliminate the need for separate transceivers, simplifying cable management and reducing total cost of ownership.

Suitable for

• Data center top-of-rack to server connections
• High-performance computing (HPC) clusters
• Enterprise network aggregation
• Telecommunications infrastructure
• Any application requiring 100G to 4x25G breakout

Recommendations

For optimal performance, ensure that both ends of the cable are securely connected and that the host devices support the respective QSFP28 and SFP28 interfaces. This cable is ideal for short-reach interconnects within racks or adjacent racks. For longer distances, consider active optical cables or transceivers with fiber.
