Integrated optical transceiver apparatus and optical line terminal

Abstract

Embodiments of an integrated optical transceiver apparatus and an OLT are provided. A first splitter and a second splitter are integrated into a PLC structure of the apparatus. The first splitter is configured to output a signal light of a first wavelength and a signal light of a second wavelength, and output a signal light of a third wavelength and a signal light of a fourth wavelength. The second splitter is configured to separate the signal light of the third wavelength and the signal light of the fourth wavelength, and output the signal light of the third wavelength, and output the signal light of the fourth wavelength. A first optical detector and a second optical detector are disposed on the PLC structure, where the first optical detector and the second optical detector are configured to convert, into electrical signals, the signal lights output by the second splitter.
