Abstract(in English) | We propose a cord identification technique for ultra-low bending loss fiber using higher order modes of visible light. The bending loss of higher order modes is several orders larger than that of fundamental modes. Higher order modes can exist at shorter wavelengths and their guiding loss is small when the fiber is not tightly bent. As a result, higher order modes are suitable for cord identification purposes with ultra-low bending loss fiber. We determined that the LP_<21> and LP_<02> mode group at 650nm (red) and the LP_<31> and LP_<12> mode group at 532nm (green) are the most effective for cord identification purposes. We employed an offset launch technique to excite higher order modes, and achieved a sensitivity improvement of more than 14dB. By using our method, a cord can be identified by red or green light even with the naked eye. |
