Abstract

The macro-bending based fiber identification technique is widely used to identify optical fibers at the worksite. Bending-loss insensitive fibers have been receiving increasing attention, however it is difficult to apply the macro-bending based fiber identification technique to these fibers. In this paper, we propose a new fiber identification technique based on a mechanically induced long-period grating (LPG), and show that the proposed technique can be utilized for a hole-assisted fiber with an extremely low bending loss. We also propose combining the chirped LPG technique with our fiber identification method to simultaneously specify fibers with different structures.
