OPTICAL LINE TERMINAL AND METHOD THEREOF FOR PROCESSING AMPLIFIED SPONTANEOUS EMISSION

摘要

An optical line terminal, including: an optical power amplification module (501), an optical power attenuation module (502), an optical power attenuation magnitude control module (503) and an optical module (504). The optical power amplification module (501), the optical power attenuation module (502) and the optical module (504) are connected successively. The input end of the optical power attenuation magnitude control module (503) is connected to the optical module (504), and the output end thereof is connected to the optical power attenuation module (502). The optical power attenuation module (502) is used for reducing the optical power of amplified spontaneous emission generated by the optical power amplification module (501), the optical module (504) is used for converting the amplified spontaneous emission after being attenuated by the optical power attenuation module (502) into an electric signal and outputting signal detection information, and the optical power attenuation magnitude control module (503) is used for receiving the signal detection information emitted by the optical module (504) and controlling the attenuation magnitude of the optical power attenuation module (502) in real time. A method for processing amplified spontaneous emission.
