IEC 61756-1:20 19涵盖了光纤管理系统接口的一般信息。它包括创建光纤管理系统界面的定义和规则，还提供了识别存储光纤的最小弯曲半径的标准。该文件允许使用单模和多模光纤。本文件不包括电缆入口区域或电缆元件末端的液体、气体或灰尘密封要求。这第二版取消并取代了2006年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更: -添加附图以示出保护性外壳和光纤管理系统之间的接口； -增加了保护外壳、封闭件、壁盒、街柜和光配线架模块的定义；-添加具有熔接保护器和机械接头尺寸的表格； -增加识别储存纤维的最小弯曲半径的方法； -增加有关光纤管理系统的其他因素的条款； -增加附件A，例如计算纤维管理系统中储存纤维的最小弯曲半径。 关键词:光纤管理系统接口，存储光纤的最小弯曲半径

IEC 61756-1:2019 covers general information on fibre management system interfaces. It includes the definitions and rules under which a fibre management system interface is created and it provides also criteria to identify the minimum bending radius for stored fibres. This document allows both single-mode and multimode fibre to be used. Liquid, gas or dust sealing requirements at the cable entry area or cable element ending are not covered in this document. This second edition cancels and replaces the first edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- addition of figures to show the interface between protective housing and fibre management system;
- addition of definitions for protective housing, closure, wall box, street cabinets and optical distribution frame modules;
- addition of table with dimensions of fusion splice protectors and mechanical splices;
- addition of method to identify the minimum bending radius for stored fibres;
- addition of clause for other factors relevant to fibre management systems;
- addition of annex A for example of calculating the minimum bending radius of stored fibres in a fibre management system.
Keywords: fibre management system interfaces, minimum bending radius for stored fibres
