ABSTRACT

This paper shows the status of the ethernet-based communication solutions, focused on optical links, for the automotive industry. First, the implementation of a product compatible with the 1000BASE-RHC according to the IEEE Std 802.3bv is presented, which is the first able to transmit 1 Gbps over POF (Plastic Optical Fiber) for automotive. Second, a new architecture to achieve up to 25 Gbps for automotive is described. The proposed Multi-Gigabit system leverages existing technologies, as VCSELs (Vertical-cavity surface-emitting laser), multi-mode fibers and photodiodes already developed for the data centers industry.

摘要

本文展示了针对汽车行业的基于以太网的通信解决方案（专注于光链路）的现状。首先，提出了一种与IEEE Std 802.3bv兼容的与1000BASE-RHC兼容的产品的实现方案，这是第一个能够通过用于汽车的POF（塑料光纤）传输1 Gbps的产品。其次，描述了一种用于汽车的高达25 Gbps的新架构。拟议的Multi-Gigabit系统利用了现有技术，例如已经为数据中心行业开发的VCSEL（垂直腔表面发射激光器），多模光纤和光电二极管。
