"UECY" isn't a standard abbreviation I'm aware of in the context of networking cables. It might be a brand name or a specific designation used by a manufacturer. If you have more information about what "UECY" refers to, I can try to provide more specific information. Otherwise, it's likely just a label or identifier specific to the manufacturer or seller of the cable.
