Cisco 40GBASE-CR4 QSFP to 4 10GBASE-CU SFP+direct branch cable 5-meter passive

**Cisco 40GBASE-CR4 QSFP to 4x10GBASE-CU SFP+ Direct Attach Cable (5m)**

This passive copper breakout cable enables seamless connectivity between 40G QSFP+ ports and four separate 10G SFP+ ports, delivering cost-effective high-density networking solutions. The 5-meter length provides flexible rack-to-rack connections while maintaining signal integrity without requiring external power or transceivers.

**Key Benefits:**
– **Cost Efficiency**: Eliminates need for expensive optical transceivers
– **High Performance**: Supports full 40Gbps bandwidth with low latency
– **Energy Savings**: Passive design reduces power consumption and heat generation
– **Plug-and-Play**: Direct attach design simplifies installation and reduces failure points
– **Cisco Compatibility**: Engineered for optimal performance with Cisco switching infrastructure
– **Space Optimization**: Breaks out single 40G port into four 10G connections for legacy equipment integration

**Ideal Applications**: Data center spine-leaf architectures, server connectivity, network aggregation, and gradual migration from 10G to 40G infrastructure while maximizing existing equipment investments.
