    • The invented methods provide a means for reducing or eliminating manual astments that are required during the fabrication (winding) of fiber optic dispensers. This reduction is accomplished through the use of a fiber placement pattern that is permanently generated on the bobbin winding surface. Filaments, such as optical fibers, are precisely guided during the winding of subsequent filament layers by the embedded crossover pattern baselayer. The embedded crossover pattern baselayer is generated by first winding in a given direction a wire of a pre-selected diameter upon the polymer coating on the bobbin surface. The polymer is allowed to cure partially before the wire is unwound and removed. Afterwards a pre-selected optical fiber is wound in the direction opposite that of the wire winding direction thereby creating crossover patterns which are, then, manually adjusted to be in desired locations on the bobbin axis. The optical fiber is removed and the polymer is allowed to cure to a rigid, noncompliant state, thereby generating the embedded crossover pattern baselayer.
    • 本发明的方法提供了减少或消除在光纤分配器的制造(缠绕)期间所需的手动调节的手段。 这种减少是通过使用在筒管绕组表面上永久产生的纤维布置图案来实现的。 通过嵌入式交叉图案基底层在后续丝层中卷绕期间,诸如光纤之类的细丝被精确地引导。 嵌入式交叉图案基层是通过在线轴表面上的聚合物涂层上首先沿预定方向缠绕预选直径的线。 允许聚合物部分地固化,然后退绕和除去电线。 之后,将预先选定的光纤沿与线缠绕方向相反的方向缠绕,从而产生交叉图案,然后将其手动调节到绕线轴上的所需位置。 除去光纤并使聚合物固化成刚性的不合格状态,从而产生嵌入式交叉图案基底层。
