Tripp Lite QSFP+ to QSFP+ 40Gb Passive DAC Copper Infiniband Cable, 0.5M (20-in.)

The Tripp Lite N282-20N-BK is a QSFP+ to QSFP+ passive direct attach copper cable that moves data at up to 40 Gbps across a short 0.5 meter link. It gives network administrators an easy way to interconnect switches, servers, or storage devices that sit in the same rack, making it ideal for top-of-rack architectures where every watt and every inch of space counts.

This cable supports 10.3125 Gbps on each of its four channels and meets the 40GBase-CR4 specification, so it integrates smoothly with equipment that uses SDR, DDR, or QDR signaling. Because it relies on copper rather than optics, it draws less power, creates less heat, and costs less to deploy in high-density environments such as data centers, high-performance computing clusters, and enterprise server rooms.

Installation is straightforward. Each end has a zinc die-cast QSFP+ connector that follows the SFF-8436 standard and includes a pull-to-release latch, so technicians can secure or remove the cable without special tools and without disturbing neighboring ports. The 20-inch length minimizes slack, which helps maintain clean cable management and unobstructed airflow.

The cable is fully compliant with RoHS and IEEE 802.3ba requirements, and it delivers a bit error rate better than 10¹², ensuring consistent performance in demanding workloads such as virtualization, real-time analytics, and large-scale data replication.
