道路车辆车内以太网第5部分:光学1-Gbit/s物理层系统要求和试验计划

[中文适用范围]： 本文件规定： ——系统级物理层的要求， — 互操作性测试设置的要求， — 检查系统级物理层要求的互操作性测试计划， — 设备级物理层一致性的要求测试设置，以及 — 设备级物理层一致性测试计划，用于检查与设备供应商相关的 OSI 物理层的一组要求。 互操作性测试计划检查本文档和 ISO/IEC/IEEE 8802-3:2017/Amd 9 中指定的物理层系统要求。 该测试计划分为四个不同的测试组，关注涵盖以下内容的系统要求类型： : ——链路状态，包括通过使用可用寄存器的内容及其与链路实际状态的准确性来检查链路状态的测试， — 链路接通，包括检查链路状态的测试IUT从某种状态达到可靠的链路状态， — 通道质量，包括通过使用可用寄存器的内容及其与光通道实际质量的准确性来检查光通道质量的测试，以及 — 唤醒唤醒和睡眠，其中包括检查唤醒和睡眠事件的传输和接收的测试。 器件级一致性测试计划检查本测试计划中指定的器件级要求。 该测试计划分为四个不同的测试组，关注所需的测试设置： ——高衰减通道， — 低衰减通道， — 光学IUT 发射机测量，以及 — 唤醒和同步链路睡眠。  [外文原描述]： This document specifies: — requirements on the physical layer at system level, — requirements on the interoperability test set-ups, — interoperability test plan that checks the requirements for the physical layer at system level, — requirements on the device-level physical layer conformance test set-ups, and — device-level physical layer conformance test plan that checks a set of requirements for the OSI physical layer that are relevant for device vendors. The interoperability test plan checks the physical layer system requirements specified in this document and in ISO/IEC/IEEE 8802-3:2017/Amd 9. This test plan is structured in four different test groups, attending to the kind of system requirements that covers: — link status, that includes the tests that check the status of the link by using the content of the available registers and its accuracy with the real status of the link, — link-up, that includes the tests that check the time that the IUT reaches a reliable link status from certain state, — channel quality, that includes the tests that check the quality of the optical channel by using the content of the available registers and its accuracy with the real quality of the optical channel, and — wake-up and sleep, that include tests that check that the transmission and reception of the wake-up and sleep events. The device-level conformance test plan checks the device-level requirements specified in the ISO 21111 series and in ISO/IEC/IEEE 8802-3:2017/Amd 9. This test plan is structured in four different test groups, attending to the test set-up required: — high-attenuation channel, — low-attenuation channel, — optical IUT transmitter measurements, and — wake-up and synchronised link sleep.
