在其中一个实施例中，牵引轮4牵引光纤依次经过包层直径检测仪1、涂覆层直径检测仪2和麻点切割检测仪3并检测光纤。
在其中一个实施例中，包层直径检测仪1检测结果大于126微米或小于124微米时，该处光纤不合格，可编程控制器6上传检测结果至数据库5。

在其中一个实施例中，牵引轮4上设有计数器，计数器记录牵引轮4转动数并传输至可编程控制器6。通过记录牵引轮4转动数，可用于计算光纤段长。
在其中一个实施例中，在可编程控制器6中预设有光纤最小段长，可编程控制器6根据计数器计算光纤段长，光纤段长小于预设的光纤最小段长时，该处光纤不合格，可编程控制器6上传检测结果至数据库5。

本发明的有益效果是：本发明将原有的不合格光纤位置存储至一个位置，可编程控制器会同时对各种不合格光纤同时进行处理运算，并根据设定的不合格光纤指标和不满足最小段长的合格光纤去除并自动上传数据库，从而实现自动控制；自动处理的方式避免了可能出现的错算，漏算，造成不合格光纤的流出，合格光纤的报废；节约了不合格光纤的计算、录入数据库时间，并使所拉光纤能够得到及时检测，减少后续不良品的产生。
