摘要： In one embodiment, a process for manufacturing an optical fiber coupler of the invention utilizes a rotating drum that has a sloted portion or stacking slot for receiving multiple lengths of fiber in a stack. A support for the input ends of the fibers is in the form of a block which is secured to the surface of the drum in spaced relation with the slot. The block has a plurality of shallow, parallel spaced apart grooves in parallel alignment with the stacking slot. An end of the fiber is initially threaded preferably into the stacking slot and then sequentially located alternately in vacant grooves in the support. As the drum is rotated, a positioner operates to move the fiber transversely in the direction parallel to the drum axis so as to align the fiber in each respective one of the grooves and the slot for each rotation of the drum. The process continues until all the grooves are all occupied and the stacking slot is filled with a corresponding number of fiber lengths. The stacked output ends of the fibers are secured together by an appropriate adhesive and the input ends of the fibers are likewise secured in the grooves of the block by an appropriate adhesive. The fibers are severed at the input and output ends to allow for removal of one or more devices from the drum. The invention also includes the apparatus for performing the process and the resulting optical fiber coupler.
摘要翻译：在一个实施例中，本发明的光纤耦合器的制造方法利用旋转滚筒，该旋转滚筒具有用于在堆叠中接收多束纤维的折边部分或堆叠槽。对于纤维的输入端的支撑件是以与槽成间隔开的方式固定到滚筒表面的块的形式。该块具有与堆叠槽平行对准的多个浅的，平行的间隔开的槽。纤维的端部最初被优选地插入到堆叠槽中，然后顺序地定位在支撑件中的空槽中。当滚筒旋转时，定位器操作以沿着平行于鼓轴线的方向横向移动纤维，以便在滚筒的每个旋转中将纤维对准在每个相应的一个槽和槽中。该过程一直持续到所有的凹槽全部被占用，并且堆叠槽被填充相应数量的光纤长度。纤维的堆叠输出端通过适当的粘合剂固定在一起，并且纤维的输入端同样通过适当的粘合剂固定在块的凹槽中。纤维在输入和输出端被切断，以允许一个或多个装置从滚筒中移出。本发明还包括用于执行处理的装置和由此产生的光纤耦合器。
