| Zusammenfassung: | The optical losses and reflection ratio of a connector and a splice and physical characteristics of optical cable are easily measured by using the integrated optical circuit. The circuit comprises a main wave guide (2) formed on a substrate (1), a sub-wave guide (2), a direction coupler (6) formed on an area on which the main and the sub wave guide are located closely, and a loop reflector (5) formed at the end of the sub wave guide (3). |
