BlueLAN Cable breakout Direct Attach QSFP-DD 400G a 4x 100G QSFP56, 1m, cobre pasivo, AWG26, compatible con Arista CAB-D-4Q-400G-1M-BL

This passive direct attach breakout cable delivers 400G aggregate bandwidth by splitting one QSFP-DD port into four QSFP56 ports, each running at 100G. It is engineered for Arista Networks switches and is compatible with the CAB-D-4Q-400G-1M part number.

Advantages

Passive copper construction ensures low latency and zero power consumption, while the 1-meter length with AWG26 wire gauge provides a flexible, cost-effective interconnect for high-density rack deployments. The breakout configuration simplifies cabling from 400G ports to multiple 100G devices.

Suitable for

• Data center top-of-rack to server connections
• High-performance computing clusters
• Arista 400G QSFP-DD switch ports

Key specifications

• Aggregate data rate: 400 Gbps (4x 100 Gbps)
• Connector A: QSFP-DD (400GBASE-CR8)
• Connector B: 4x QSFP56 (100GBASE-CR each)
• Cable length: 1 meter
• Wire gauge: AWG26
• Passive copper technology
• Hot-pluggable

Recommendations

Ideal for short-reach, high-density 400G-to-100G connectivity in Arista environments where power and latency are critical.
