The invention discloses a vehicle-mounted network system based on optical fiber wavelength division multiplexing and a transmission method, wherein the vehicle-mounted network system comprises: a fiber optic communication channel through the vehicle; a wavelength division multiplexer disposed. We designed an in-vehicle communication system using wavelength division multiplexing and studied its characteristics in various environments. Since a single optical fiber can transmit multiple wavelengths of light, it is assumed that this will lead to a reduction in the number and weight of cables. Aspects of the subject disclosure may include, for example, collecting information about network nodes and network branches in a waveform-division multiplexing-passive optical network (WDM-PON), forming an embedding model based on the information about network nodes and network branches, receiving. Learn how custom fiber optics from FSI enhance automotive design, enabling high-speed data, EMI resistance, and future-ready vehicle architectures. The Expanding Role of Fiber Optic Systems in Automotive EngineeringAs vehicles evolve into connected data hubs on wheels, the need for high-bandwidth. Wavelength Division Multiplexing (WDM) in fiber optics has revolutionized the way data is transmitted and has become an integral part of modern communication networks. By utilizing different wavelengths of light to carry multiple signals simultaneously over a single optical fiber, WDM technology.
