Keep 40 GbE links short, predictable, and cost-efficient with this AddOn compatible QSFP+ direct attach cable. Designed for adjacent rack and top-of-rack connections, the 1 m passive twinax assembly delivers a straightforward copper path for 40GBASE-CU deployments where optical transceivers are unnecessary. This cable is a practical fit for infrastructure teams that want to simplify high-speed interconnects without sacrificing signal integrity over short distances. Its QSFP+ interface supports dense switch-to-switch, switch-to-server, and aggregation-layer connections while helping reduce power consumption and heat compared with optical alternatives. TAA compliance makes it suitable for procurement environments with sourcing requirements, and the compatible design gives teams a lower-friction replacement option for supported Alcatel-Lucent environments. For data centers standardizing on short-reach 40 GbE copper links, it offers the right balance of performance, simplicity, and deployment speed. Use it where the run is short, the port density is high, and the cost of over-specifying optics adds no value. This is the kind of cable that earns its place in production by doing one job well: carrying 40 GbE traffic cleanly between nearby devices.
