IEC 62343的这一部分提供了波长选择开关的性能规范模板。其目的是为波长选择开关性能详细规范的编制提供一个框架。 如有必要，详细的产品规格或性能规格通常包括附加规格参数。但是，本文件中规定的规范参数不会从详细的产品规范或性能规范中删除。 关于波长选择开关及其在单模光纤DWDM系统中的应用的技术信息，请参见IEC TR 62343-6-4。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This part of IEC 62343 provides a performance specification template for wavelength selective switches. The object is to provide a framework for the preparation of detail specifications on the performance of wavelength selective switches. Additional specification parameters are often included for detailed product specifications or performance specifications if necessary. However, specification parameters specified in this document are not removed from the detail product specifications or performance specifications. The technical information regarding wavelength selective switches and their applications in DWDM systems with single-mode fibres are described in IEC TR 62343-6-4.All current amendments available at time of purchase are included with the purchase of this document.
