—第3部分:A3类多模光纤特性;

—第4部分:A4类多模光纤特性。

本部分为GB/T12357的第3部分。

本部分修改采用IEC60793-2-30((光纤第2-30部分:产品规范—A3类多模光纤特性)}(英文

版)本部分根据IEC60793-2-30;2002起草。

考虑到我国国情，在采用IEC60793-2-30;2002时，本部分做了一些修改:删除了附录A、附录B,

b)用小数点“.”代替作为小数点的逗号“，”。

本部分对GB/T12357-1990《通信用多模光纤系列》相应部分进行修订。本部分与

GB/T12357-1990中A3类多模光纤相比主要变化如下:

—将标准题目由《通信用多模光纤规范》改为多《模光纤第3
