BlueLAN QDD-4X100G-2M-BL Juniper Compatible 400G QSFP-DD Breakout DAC Cable 2m AWG26

Data center technicians deploying high-density 400G Ethernet fabrics use the BlueLAN QDD-4X100G-2M-BL to connect a QSFP-DD port to four QSFP56 ports on Juniper switches, routers, or servers. This passive direct attach copper breakout cable delivers a total bandwidth of 400 Gbps across four 100 Gbps lanes, providing a cost-effective, low-latency interconnect for short-reach links within racks or adjacent racks.

Key specifications

• Connector A: QSFP-DD
• Connector B: 4x QSFP56
• Aggregate data rate: 400 Gbps (4x 100 Gbps breakout)
• Cable length: 2 meters
• Wire gauge: AWG26
• Cable type: Passive Direct Attach Copper (DAC)
• Compatibility: Juniper Networks
• Hot-swappable: Yes

Why choose it

This cable eliminates the need for separate transceivers and fiber patch cords, reducing cost and power consumption. Its passive design consumes no additional power and introduces minimal latency, ideal for latency-sensitive applications. The breakout configuration simplifies migration to 400G while leveraging existing 100G QSFP56 ports.

Ideal use cases

• High-performance computing clusters
• Data center spine-leaf architectures
• Enterprise network core upgrades
• Short-reach server-to-switch connections

Good to know

Compliant with IEEE 802.3 Ethernet standards and RoHS. The cable is hot-swappable, allowing for easy installation and maintenance without network downtime.
