CORE FIBER CHECK DEVICE AND CORE FIBER CHECK METHOD |
| 摘要 |
<p>A core fiber check device capable of core fiber check of a holey single-mode optical fiber is disclosed. The check device includes a grating forming tool (20) for forming a grating by exerting a load F onto an optical fiber (1) by means of ridges (23) and a photodetector (30) for detecting leakage light ?1' produced in the optical fiber (1). The ridges (23) are arranged with a spacing ? of 0.24 to 0.75 mm.</p> |
