StarTech QSFP40GPC05M QSFP+ Twinax Cable, 0.5 m

Maintain high-speed connectivity between adjacent switches, servers, and storage with a QSFP+ direct-attach twinax cable designed for short-reach 40 GbE deployments. The 0.5 m copper assembly helps reduce clutter in tightly packed racks while preserving the electrical characteristics needed for reliable link performance. Built to comply with MSA industry standards, this cable is intended for environments where interoperability matters as much as physical fit. It is a practical choice for data center teams that want a direct-attach option instead of a more expensive optical path for very short distances. The twinax design supports clean, low-profile routing between equipment mounted in the same rack or neighboring enclosures. For infrastructure teams, the value is in the balance of cost, simplicity, and performance. When the run is short and the port count is high, a copper direct-attach cable can reduce complexity without sacrificing the connectivity required for production workloads. StarTech’s QSFP40GPC05M is built for that exact use case: short, direct, and dependable.
