Product Features
Technical Overview
This cable operates as a passive direct attach copper (DAC) solution, meaning it does not require external power or signal processing electronics, which enhances reliability and reduces latency. The 40GBASE-CR4 standard supports breakout configurations, allowing one QSFP+ port to connect to four 10GBASE-CU SFP+ ports, optimizing port utilization and flexibility in network designs.
With a precise length of 3.3 feet, it is tailored for short-reach applications, minimizing cable clutter while maintaining performance. The male QSFP+ and SFP+ connectors ensure secure, hot-pluggable connections that meet industry standards for network infrastructure.
Key Product Advantages
This cable offers significant advantages for network administrators seeking efficient, high-speed connectivity without the complexity of active components. Its passive design reduces power draw and cooling requirements, contributing to lower operational costs in dense deployments.
Cost-Effective Connectivity
By integrating the cable and connectors into a single unit, it eliminates the need for separate transceivers, lowering both initial investment and maintenance overhead compared to fiber-based solutions.
- No external power needed
- Reduces component count
- Simplifies inventory management
Enhanced Reliability
The passive copper construction minimizes points of failure, providing a durable connection that resists signal degradation over its specified length, ensuring consistent network performance.
- Stable signal integrity
- Durable build quality
- Low latency operation
Deployment / Use Cases
This cable is ideal for data centers, enterprise networks, and high-performance computing environments where short-distance, high-bandwidth connections are required. It facilitates efficient interconnectivity between switches, routers, servers, and storage devices equipped with QSFP+ and SFP+ ports.
Common use cases include linking top-of-rack switches to servers within the same rack, connecting aggregation switches in network closets, and enabling high-speed backbone links in virtualized or cloud infrastructure. Its Intel compatibility ensures seamless integration with a wide range of network hardware, supporting scalable and future-proof deployments.
Data Center Interconnects
Use for spine-leaf architectures or within server racks to achieve 40GbE speeds without the cost and complexity of fiber optics, optimizing space and power efficiency.
Enterprise Network Upgrades
