WDM相关标准导读（201006）培训教材电子互联

WDM相关标准导读设备需要符合相关标准标准是设备设计的依据标准是对设备的最基本要求，设备需要优于标准标准是不同厂家设备互联互通的基础标准不是决定的，一成不变的工作中几种场景设备是否符合某个标准？-----如何找到该标准，了解要求？要求设备满足某项功能或指标-----要求是怎样的，需要查找哪些标准？设备满足哪些标准？标准的术语和定义产品标准按GB/T20000.1-2002中2.5.4节规定：产品标准（ProductStandard）规定产品应满足的要求以确保其适用性的标准。注1：产品标准除了包括适用性的要求外，还可直接地或通过引用间接地包括诸如术语、抽样、测试、包装和标签等方面的要求，有时还可包括工艺要求。注2：产品标准根据其规定的是全部的还是部分的必要要求，可区分为完整的标准和非完整的标准。同，产品标准又可区分为其他不同类别的标准，例如尺寸类标准，材料类标准和交货技术通则类标准。按标准发生作用的范围和审批标准级别来分，我国的标准将标准分为：国家标准，由国务院标准化行政主管部门负责组织制定和审批；行业标准由国务院有关行政主管部门负责制订和审批，并报国务院标准化行政主管部门备案行业标准，地方标准（通信行业没有地方标准，农产品，药材等地域强的产品有地方标准），地方标准由省级政府标准化行政主管部门负责制订和审批，并报国务院标准化行政主管部门和国务院有关行政主管部门备案企业标准，由企业制订，由企业法人代表或法人代表授权的主管领导批准、发布，由企业法人代表授权的部门统一管理，企业产品标准应向当地标准化行政主管部门和有关行政主管部门备案。标准的附录：资料性附录、规范性附录、APPENDIX、ANNEX公司具有会员资格的传送网相关标准化组织中国通信标准化协会(CCSA):
