| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In the FTTH era, we must provide effective and efficient maintenance for optical cable networks. With a view to realizing a highly reliable optical cable network, we should improve optical testing technique. This paper describes a high spatial resolution OTDR measurement technique for optical access networks, which employs optical filters installed at the end of optical fiber lines. This technique can measure bending or splice losses in an attenuation dead zone just behind the Fresnel reflection of an optical splitter by using a dead-zone-free signal analysis method. | |
