摘要： An integrated optical transceiver apparatus and an OLT are provided. A first splitter (11) and a second splitter (12) are integrated into a PLC structure (10) of the apparatus. The first splitter (11) is configured to output, from a second end (11b) of the first splitter (11) to an optical fiber (2), signal light of a first wavelength and signal light of a second wavelength that are received by a first end (11a) of the first splitter (11), and output, from a third end (11c) of the first splitter (11), signal light of a third wavelength and signal light of a fourth wavelength that are received by the second end (11b) of the first splitter (11) from the optical fiber (2). The second splitter (12) is configured to separate the signal light of the third wavelength and the signal light of the fourth wavelength that are output by the third end (11c) of the first splitter (11), output the signal light of the third wavelength from a second end (12b) of the second splitter (12), and output the signal light of the fourth wavelength from a third end (12c) of the second splitter (12). A first optical detector (21a) and a second optical detector (21b) are disposed on the PLC structure (10), where the first optical detector (21a) and the second optical detector (21b) are respectively configured to convert, into electrical signals, the signal light output by the second end (12b) of the second splitter (12) and the signal light output by the third end (12c) of the second splitter (12). The apparatus can implement sending and receiving of dual-wavelength signal light.
