Modular cable assemblies are specialized cable assemblies designed to connect devices using modular connectors, commonly including RJ-style connectors (such as RJ11, RJ12, RJ45) for telecommunication, networking, and data transmission applications. These cables typically consist of insulated conductors arranged in parallel within a flexible jacket and terminated with modular plugs that provide standardized, reliable connections. The modular design ensures easy plug-and-play installation, secure mating, and consistent electrical performance.
