It is widely compatible with 400G IB/Ethernet, switches, servers, routers, supercomputing centers, cluster networks, and other applications.

Technical Principles and Core Design

The 400G QSFP112 DAC leverages high-speed differential signal transmission principles and utilizes the QSFP112 form factor to achieve high-density, high-speed data transfer. Its multi-protocol compliance ensures seamless compatibility with network devices from various brands and models. With wire gauge options ranging from 26 to 30 AWG, it strikes a balance between transmission distance and wiring flexibility: thicker gauges are ideal for short-distance, highly stable transmission, while thinner gauges facilitate installation in tight spaces. The EMI-resistant design employs optimized shielding layers and signal isolation structures to effectively reduce electromagnetic radiation’s impact on surrounding equipment and resist external electromagnetic interference, thereby ensuring stable high-speed data transmission. Hot-swapping functionality is enabled through a dedicated interface design and circuit protection mechanisms, allowing cable insertion or removal during device operation without requiring a reboot, thus improving operational efficiency. Meanwhile, the low-power design optimizes signal transmission circuits and selects appropriate chips to minimize energy consumption during cable operation, helping save power costs in large-scale deployments such as data centers.
