PCI-SIG®, the organization responsible for the widely adopted PCI Express® (PCIe®) standard, announced the release of the CopprLink™ Internal and External Cable specifications on May 1st. These specifications extended the applications of PCIe channels, including applications such as storage, data center, artificial intelligence, machine learning and disassemble memory, etc. At present, Zhaolong Interconnect already has comparatively abundant high-speed internal and external connection product solutions for server interconnection. Among them, Zhaolong's high-speed external cable solutions (e.g. SFF-1032 CDFP x16 Cable Assembly for PCIe 5.0) are mainly used in the expansion interconnection of GPU cards; and Zhaolong's high-speed internal cable solutions include...

Because of this, RDMA is especially suitable for scenarios that have extremely high performance requirements and are extremely sensitive to latency. As one of Zhaolong’s LONGSPEEDTM Ethernet high-speed interconnection solutions, QSFP-DD 800G DAC has demonstrated excellent performance in supporting RDMA network, becoming a powerful weapon to reduce latency.

For smaller-scale data centers, deploying high-speed copper interconnects—such as Direct Attach Copper (DAC), Active Copper Cables (ACC), and Active Electrical Cables (AEC)—ensures low-latency, high-throughput intra-data center connectivity, as validated by industry benchmarks. This article explores this paradigm shift and its practical implementation.

Twinax Cables Power AI Data Centers​​： AI’s boom drives data centers to ultra-high speeds (400G–1.6T). Twinax cables, key connective media for DAC/ACC/AEC, emerge as "transmission powerhouses" (28G–224G) via low-latency, high-bandwidth, anti-interference design. Zhaolong’s HSC bare wires, using self-developed FEP foam and silver-plated copper, offer cost-effective solutions (32–26AWG, 2–16 pairs, 28G–224G). Lightweight, foldable, they save space/power vs fiber, boosting client tech leadership in AI/HPC/data centers.
