Designed for High-Speed Data Centers

The Huawei QSFP28-100G-CU1M is specifically engineered for short-distance interconnections inside modern data centers where high bandwidth and minimal latency are essential. Instead of using separate optical transceivers and fiber cables, this integrated DAC solution combines both connectors and cable into one factory-tested assembly. This significantly reduces installation complexity while lowering deployment costs.

The cable provides stable 100GbE connectivity between switches, servers, storage systems, virtualization platforms, GPU clusters, and high-performance computing environments. Its passive copper design eliminates the need for additional power inside the cable while maintaining reliable high-speed transmission.

Excellent Performance and Reliability

Huawei manufactures the QSFP28-100G-CU1M according to strict enterprise networking standards. Every cable undergoes comprehensive factory testing to ensure stable signal quality, excellent electromagnetic compatibility, and dependable long-term operation. This makes it suitable for mission-critical business environments where continuous network availability is required.

The passive DAC architecture reduces power consumption compared to active optical solutions while maintaining outstanding transmission quality over short distances. This contributes to lower operating costs and improved energy efficiency throughout the network infrastructure.

Easy Installation

Installation is extremely simple. Network administrators only need to insert both QSFP28 connectors into compatible Huawei switches or network devices. No additional configuration, calibration, or optical cleaning is required. The plug-and-play functionality enables quick deployment while minimizing downtime during upgrades or maintenance.

The fixed 1-meter cable length is ideal for rack-to-rack and top-of-rack deployments where equipment is installed close together. Cable management also becomes much easier due to the compact design.

Perfect for Enterprise Networking

The Huawei QSFP28-100G-CU1M is widely used in enterprise data centers, cloud computing environments, virtualization infrastructure, financial institutions, Internet service providers, telecommunications companies, universities, healthcare organizations, and government networks. It supports applications that require consistent high-speed connectivity with minimal packet loss and stable throughput.

Whether connecting aggregation switches, core switches, storage devices, blade servers, or hyper-converged infrastructure, this cable delivers dependable performance that meets modern networking requirements.

Cost-Effective Alternative to Fiber

For short-distance connections, passive DAC cables provide significant savings compared to optical modules. Since the cable includes permanently attached QSFP28 connectors, there is no need to purchase separate transceivers and fiber patch cords. This reduces hardware costs while simplifying inventory management.

Organizations deploying hundreds of high-speed switch ports can significantly reduce their networking budget without sacrificing reliability or performance.
