摘　　要：本文介绍日本在光纤到家(FTTH)网络中用户室内应用的弯曲不敏感孔助光纤(HAF)。讨论了这种光纤的弯曲损耗与模场直径对于孔设计的依赖关系。文章接着介绍了用这种光纤制作的卷曲软光缆。这种软光缆具有螺旋结构,它容许伸长缩短而不增加损耗。因此,在用户宅内应用时,能够在它的两端配各在工厂预装的连接器。利用这种特性能够实现一个经济而灵活的布线系统。The paper introduces the bend-insensitive hole-assisted fiber used in subscribers＇ premises in FTTH network in Japan. The dependence of bending loss and mode field diameter on the hole design is discussed. The optical curl cords using the hole-assisted fibers have spiral structure, which allows the cord to lengthen and shorten without added loss. Therefore, when used in subscribers＇ premises, factory assembled connectors can be attached to both ends of the cords. By utilizing this feature, an economical and flexible cabling system can be realized.
