This dissertation investigates the development and integration of high-performance optical data transmission systems into conventional and planar automotive wiring harnesses. The research focuses on polymer-clad silica (PCS) fibers with a core diameter of 200 µm and vertical-cavity surface-emitting lasers (VCSELs) operating at 850 nm. Experimental investigations and optical simulations examine modal excitation, coupling efficiency, bandwidth, temperature resistance, and transmission losses. The study demonstrates the integration of optical fibers into flexible flat cables and the fabrication of planar optical waveguides and passive optical star couplers. Additionally, connector systems and microstructured coupling modules are developed to integrate optoelectronic components with planar waveguide structures. The findings show that PCS/VCSEL-based systems provide higher optical power margins, improved thermal stability, and more flexible network architectures than conventional polymer optical fiber systems. The research establishes a technical foundation for compact, reliable, and high-bandwidth automotive optical communication networks.
