BlueOptics 40G QSFP+ to 4x SFP+ Passive Direct Attach Copper Breakout Cable, 3m, Blue

The BlueOptics 40G-QSFP-4SFP-PC-3M-BL is a high-performance QSFP+ to 4x SFP+ breakout direct attach copper (DAC) cable, designed for reliable 40 Gigabit Ethernet connectivity in data centers and enterprise networks. This passive cable provides a cost-effective solution for connecting a 40G QSFP+ port to four 10G SFP+ ports, supporting IEEE 802.3ba 40GBASE-CR4 standards.

Advantages

This breakout cable offers significant advantages over optical transceivers, including lower power consumption (0W), reduced latency, and cost savings. The passive design ensures no additional power draw, making it ideal for high-density environments. The blue color aids in easy identification and cable management.

Suitable for

• Data center interconnects between 40G switches and 10G servers or storage
• Network attached storage (NAS) connectivity
• Server connectivity in enterprise networks
• High-performance computing clusters
