400G OSFP to 400G QSFP-DD DAC

The 400G OSFP to 400G QSFP-DD Direct Attach Copper (DAC) cable provides a high-speed, cost-effective solution for establishing 400-Gigabit links over very short distances. It is specifically designed for connecting 400G ports of switches and routers within racks or across adjacent racks in data centers. This cable delivers reliable performance while minimizing costs, making it an excellent choice for applications requiring efficient and short-distance connectivity. Constructed with ultra-low-loss materials, the cable features square rings, twisted pair wiring with eight wires, and a shell extension design. These advanced mechanical properties ensure superior durability, flexibility, and bending performance. Its robust construction optimizes cable management in high-density setups while maintaining consistent, high-quality signal transmission, even in challenging environments. Thoroughly tested in actual switching systems, the DAC ensures optimal signal integrity and delivers top-tier end-to-end performance. This makes it a highly reliable choice for demanding applications, including Artificial Intelligence (AI), Software-Defined Networking (SDN), Machine Learning (ML), and cloud computing environments, where low latency and high throughput are critical.
