"随着汽车产业智能化进程的推进，现今的智能网联汽车需要部署大量传感器和显示终端，这对车辆内 部数据传输通道的带宽与传输速率提出了极高要求。"烽火通信技术研究中心总经理罗文勇在接受科技 日报记者采访时表示。 以显示屏为例，单个未压缩的车载4K屏的带宽需求已超过每秒10G，即使经过压缩，仍需2G—4G的带 宽。在传统的车内通信模式下，汽车主要采用铜线缆传输数据，存在带宽较低、易受外界电磁干扰等问 题，难以适配智能网联汽车的高带宽与集中式架构需求。产业升级急需一种全新的底层通信技术作为支 撑，V-PON车载光通信解决方案应运而生。 罗文勇介绍，该方案引入了家庭"光纤到户"中广泛使用的无源光网络（PON）技术，以电信局端设备为 中央控制节点，通过光纤连接显示屏、摄像头等终端，形成点到多点的传输架构；同时，凭借光信号， 在单根线缆中实现上行与下行的高速传输。此外，通过网络架构优化，该方案还可将车辆所需线缆长度 减少，使高速率信号线缆重量最多减少90%，显著降低车辆自重，契合智能汽车轻量化发展需求。 如今，拉开一辆新车的车门，通常看不到传统的仪表盘、空调和座椅控制按钮、换挡杆。控制屏、高清 摄像头、激光雷达等一项项新设备 ...
