Specifying Industrial USB-C, MiniSAS and OCuLink Cables: Signal, Power and Harness Discipline
When a machine ships with the wrong cable, the failure shows up on the customer's floor, not yours. The search term industrial USB-C MiniSAS OCuLink cable manufacturer returns plenty of catalogs, but catalog depth is not the same as production discipline. A maker who builds USB-C, MiniSAS and OCuLink assemblies to documented specs — Link-Lungkay is one such cable specialist — earns trust through the paperwork as much as the product. This article is for engineers who specify cables for equipment, not for buyers chasing the lowest quote. We cover signal integrity, conductor sizing, harness documentation, qualification testing, and how to keep a cable reliable across a production run. Signal integrity is a spec, not a hope For high-speed lines — USB-C at 10/20/40Gbps, MiniSAS, OCuLink — the cable is part of the signal path. Specify insertion loss and return loss budgets, not just 'it connects'. A cable that passes on the bench but errors under vibration has a construction...
