High Speed In-Vehicle Network Connectivity Solutions

Automotive innovation is demanding faster, more secure data transmission. As the in-vehicle network (IVN) evolves, design engineers need scalable, modular connectivity that safeguards signal integrity, minimizes electromagnetic interference (EMI) and supports advanced vehicle functions in designs that meet stringent industry standards. Molex provides high-speed interconnect systems engineered to strengthen network architectures and advance the next generation of in-vehicle technologies.

Optimizing Connectivity for In-Vehicle Networks


The shift toward software-defined vehicles, zonal architecture and advanced applications is transforming the engineering of in-vehicle data exchange. As vehicles become more connected and complex, traditional communication infrastructure can no longer keep pace. The modern IVN must support continuous over-the-air updates, low-latency signals and real-time decision-making across a growing number of systems.

To meet these requirements, automotive designs are adopting modular, scalable networks that support high-speed data transmission for advanced driver assistance systems (ADAS), vehicle-to-everything (V2X) communications, infotainment and electric vehicle (EV) controls. At the same time, engineers face tighter constraints around space, weight and power consumption. Effective solutions must maintain signal integrity, minimize EMI and integrate seamlessly into dense electronic environments.

Molex components bring next-generation speeds to rapidly expanding in-vehicle networks. High-speed interconnects, compact connectors and lightweight, shielded cable assemblies from Molex are engineered to deliver data center-level transmission rates with the durability to last in tough automotive settings. From zonal control to edge sensors, Molex helps OEMs and Tier 1 suppliers build smarter, faster and more resource-efficient vehicles.
