Title: Filter element
Inventor: HAYAKAWA KOICHI
IPC: G02B6/26
Filed: 1990-03-06
Abstract: PURPOSE:To obtain a reference point which detects the absolute distance of a fault point in a line with high accuracy by embedding a filter chip formed with a filter which allows the transmission of signal light and reflects test light by a prescribed quantity into a slit formed perpendicular to the longitudinal direction of an optical fiber. CONSTITUTION:The filter element 1 is constituted by forming the slit perpendicular to the longitudinal direction of the optical fiber 3 to this optical fiber and embedding the filter chip 4 formed with the filter 4a which allows the transmission of the signal light and reflects the test light by the prescribed quantity into this slit 5. The signal light transmitted from a signal transmitting station is transmitted through the filter chip 4 to a signal receiving station side when the filter element 1 is connected to the optical fiber 3 of a transmission system. The test light is, however, reflected by the filter chip 4 to the signal transmitting station side and the filter of the signal light and the test light is thus executed. The reference point in a line monitoring system is formed in this way.
