Overview

56G QSFP+ to QSFP+ Direct Attach Cable (DAC) series offers a high-performance, cost-effective solution for short-range 56Gbps connectivity in data centers and enterprise networks. Designed for seamless integration with QSFP+ ports, these passive copper cables leverage advanced signaling technology (e.g., PAM4 modulation) to deliver 56Gbps bandwidth (4x14Gbps lanes) over distances up to 3 meters, ensuring ultra-low latency and reliable data transmission.

Ideal for interconnecting switches, servers, and storage systems, the series eliminates the need for optical transceivers, reducing power consumption and infrastructure costs. Its plug-and-play design simplifies deployment, while robust shielding ensures EMI resistance in high-density environments. Backward compatible with 40G QSFP+ systems, the cables provide a flexible upgrade path for legacy networks transitioning to higher speeds.

Engineered for durability and energy efficiency, the 56G QSFP+ DAC series is perfect for cloud computing, high-performance computing (HPC), and AI/ML clusters, balancing speed, affordability, and scalability for modern high-speed applications.
