Optical fiber splicing using leaky mode detector

摘要: Optical fiber splicing method and apparatus. The comprises aligning the ends of fibers to be spliced by a procedure comprising coupling radiation into one fibers, transmitting fiber, stripping nonfundamental mode from other receiving detecting stripped in such manner that substantial fraction detected is lowest order (LP11) for at least some relative position ends. By adjusting minimize power, are aligned. not only permits accurate alignment but can also used determine splice loss. Apparatus practice disclosed.
