100G QSFP28 DAC

Product Overview

The 100G QSFP28 DAC is a high-performance, high-speed direct-attach cable designed for high-speed network interconnects in data centers, supercomputing clusters, and other scenarios. It fully complies with industry standards such as QSFP28 MSA, IEEE802.3bj, InfiniBand EDR, and SFF-8665, ensuring high compatibility with various mainstream network devices. The product supports multiple wire gauge options from 26 to 30 AWG, enabling stable 100G transmission over distances up to 5 meters. It also offers two jacket material choices—PVC and LSZH—to meet diverse environmental adaptation needs. Featuring hot-swappable functionality, low power consumption, and EMI-resistant design, it operates within a temperature range of 0°C to 70°C and can be customized into an industrial-grade version. It is widely used for high-speed interconnections in switches, servers, routers, supercomputing centers, cluster networks, and other equipment.

Core Technical Features

This 100G QSFP28 DAC relies on rigorous protocol compliance design to ensure stability and compatibility in 100G high-speed transmission scenarios. With optional wire gauges ranging from 26 to 30 AWG, it strikes a balance between transmission distance and cable flexibility: smaller-gauge cables are lighter and more flexible, ideal for dense cabinet wiring; larger-gauge cables offer superior signal transmission stability, supporting long-distance high-speed interconnections up to 5 meters. The choice between PVC and LSZH jackets caters respectively to cost-control requirements in standard environments and the low-smoke, halogen-free, environmentally friendly material demands of data centers. Hot-swappable functionality allows cable connection and removal while devices are running, eliminating downtime and significantly boosting operational efficiency. Its low-power design effectively reduces overall device energy consumption, aligning with the trend toward energy conservation and carbon reduction in data centers. Meanwhile, the EMI-resistant design minimizes electromagnetic interference during transmission, preventing signal disruption to neighboring devices and ensuring clean network performance.
