Keep high-speed links tight, predictable, and cost-controlled with this 50 cm QSFP28 direct attach copper cable. Designed for 100GBASE-CR4 connectivity, it supports short-reach interconnects between adjacent ports where optical modules would add unnecessary expense and power consumption. This HPE compatible cable is a practical fit for top-of-rack switching, leaf-spine adjacency, and storage or server uplinks that stay within the same rack or cabinet. The QSFP28-to-QSFP28 design simplifies deployment by eliminating separate transceivers on both ends, which can reduce BOM cost and spare-part complexity. TAA compliance makes it suitable for procurement environments with sourcing requirements, while the compact 50 cm length helps keep cable management clean in high-density enclosures. For infrastructure teams standardizing on 100 GbE, it offers a straightforward way to preserve port density and maintain short, stable connections without overbuying optics for a link that does not need them.
