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， -互操作性测试计划，检查系统级物理层的要求， -设备级物理层一致性测试设置的要求，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件和ISO/IEC/IEEE 8802-3:2017/Amd 9中规定的物理层系统要求。 本测试计划分为四个不同的测试组，以满足以下系统需求: -链路状态，包括通过使用可用寄存器的内容及其与链路真实状态的准确性来检查链路状态的测试， -连接，包括检查IUT从特定状态达到可靠连接状态的时间的测试， -信道质量，包括通过使用可用寄存器的内容检查光信道质量的测试及其与光信道真实质量的准确性，以及 -唤醒和睡眠，包括检查唤醒和睡眠事件的传输和接收的测试。 设备级一致性测试计划检查ISO 21111系列和ISO/IEC/IEEE 8802-3:2017/Amd 9中规定的设备级要求。 本测试计划分为四个不同的测试组，负责所需的测试设置: -高衰减信道， -低衰减信道， -光学IUT发射器测量，以及 -唤醒和同步链接睡眠。

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.
