Keep high-speed links simple in dense infrastructure with this 40GBASE-CU direct attach cable from AddOn Networks. Built as a passive QSFP+ to QSFP+ copper assembly, it is designed for short-reach 40 GbE connectivity where predictable performance, low latency, and straightforward deployment matter more than optical transceivers. At 3 m, this cable is well suited for top-of-rack and adjacent-rack connections, helping reduce cable clutter while preserving signal integrity over short distances. The MSA and TAA compliant design supports procurement requirements for public sector and regulated environments, while the passive construction avoids the added power consumption and heat associated with active optics. For teams standardizing on QSFP+ infrastructure, this cable offers a practical way to connect switches, servers, and storage systems in high-density racks. It is a strong fit when you want dependable 40 GbE transport with minimal complexity and a clear cost advantage over optical alternatives for short runs.
