Cisco QSFP-H40G-CU1M Direct Attach Cable

The Cisco QSFP-H40G-CU1M Direct Attach Cable (DAC) is a high-performance, cost-effective solution for short-distance, high-speed networking needs. Specifically designed to support 40 Gigabit Ethernet (40GbE) applications, this cable enables efficient and reliable connectivity between switches, routers, and servers within racks and across adjacent racks in data centers.

At the core of the Cisco QSFP-H40G-CU1M DAC is its QSFP+ (Quad Small Form-Factor Pluggable Plus) transceivers, which are embedded on both ends of the copper cable. These transceivers are hot-swappable, allowing for easy installation and replacement without interrupting network operations. The 1-meter length of the cable is ideal for intra-rack and short inter-rack connections, reducing cable clutter and ensuring a clean and organized data center environment.

One of the primary advantages of using the Cisco QSFP-H40G-CU1M DAC is its ability to provide high-speed 40GbE connectivity at a fraction of the cost of traditional optical fiber cabling solutions. The direct attach copper design eliminates the need for expensive optical transceivers and fiber optic cables, making it a cost-effective choice for high-density networking scenarios. Additionally, its low power consumption compared to optical solutions helps in reducing overall energy costs in the data center.

The cable supports a data transfer rate of up to 40 Gbps, ensuring rapid and efficient data flow, which is essential for modern data center applications such as virtualization, cloud computing, and large-scale data processing. Its robust construction and reliable performance make it suitable for use in mission-critical environments where network uptime and stability are paramount.

Cisco's QSFP-H40G-CU1M DAC is compliant with the IEEE 802.3ba standard for 40GBASE-CR4 and the SFF-8436 specification, ensuring compatibility with a wide range of Cisco and third-party networking equipment. This broad compatibility allows for flexible deployment options, making it easier to integrate into existing network infrastructures.

In conclusion, the Cisco QSFP-H40G-CU1M Direct Attach Cable is an essential component for modern data centers seeking to upgrade to 40GbE connectivity. Its combination of high performance, cost-effectiveness, and ease of deployment makes it a valuable asset for enhancing network speed, efficiency, and reliability. Whether for short-distance interconnections within a rack or between adjacent racks, this DAC provides a practical solution to meet the demanding requirements of contemporary network environments.
