本部分为ＧＢ／Ｔ１５９７２的第４５部分。本部分代替ＧＢ／Ｔ１５９７２．４—１９９８《光纤总规范　第４部分：传输特性和光学特性试验方法》第１１章。本标准规定了光纤模场直径的试验方法，确立了对试验装置、注入条件、程序、计算方法和结果的统一要求。本标准适用于对B类单模光纤模场直径的测量和成品光纤光缆的商业性检验。本部分与ＧＢ／Ｔ１５９７２．４—１９９８第１１章相比主要变化如下：
———正文中对试验方法的详细描述分别用附录的形式给出（１９９８年版的１１．２、１１．３、１１．４，本版的附录Ａ、附录Ｂ、附录Ｃ）；
———增加了替代试验方法Ｄ（本版的附录Ｄ）；
———修改了光纤远场分布和近场分布的计算细节（１９９８年版的１１．１．２，本版的附录Ａ、附录Ｃ）；
———纠正了某些不恰当的叙述。
