OPTICAL RECEIVER MONITORABLE LIGHT WAVELENGTH

摘要

An optical receiver capable of optical wavelength monitoring is provided to enable an optical filter to filter an optical signal having a specific wavelength from optical signals which are split by an optical splitter and enable a controller to monitor the optical signal of the specific wavelength, thereby more easily and efficiently monitoring an optical line and operating a network. An optical splitter(10) splits optical signals which will be inputted into the first photoelectric transducer(20). An optical filter(30) filters optical signals having a specific wavelength from the optical signals which are split in the optical splitter(10). A lamp(50) controls the center wavelength filtered in the optical filter(30) according to an outputted waveform. The second photoelectric transducer(40) converts the optical signal filtered in the optical filter(10) into an electrical signal. A controller(60) monitors the optical signal having the specific wavelength through the electrical signal converted in the second photoelectric transducer(40), and controls the outputted waveform of the lamp(50).
