Title:
INTEGRATED OPTICAL TRANSCEIVER AND OPTICAL LINE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2022/161410
Kind Code:
A1
Abstract:
An integrated optical transceiver and an optical line terminal (OLT). A first splitter (11) and a second splitter (12) are integrated in a PLC structure (10) of the transceiver. The first splitter (11) is configured to transmit signal light with a first wavelength and a second wavelength received by a first end (11a) thereof from a second end (11b) thereof to an optical fiber (2), and to output, from a third end (11c) thereof, signal light with a third wavelength and a fourth wavelength received by the second end (11b) thereof from the optical fiber (2). The second splitter (12) is configured to separate the signal light with the third wavelength and the fourth wavelength outputted from the third end (11c) of the first splitter (11), and to output signal light with the third wavelength from the second end (12b) thereof, and to output the signal light with the fourth wavelength from the third end (12c) thereof. The PLC structure (10) is provided with a first optical detector (21a) and a second optical detector (21b), wherein the first optical detector (21a) and the second optical detector (21b) are respectively configured to convert the signal light outputted by the second end (12b) and the third end (12c) of the second splitter (12) into electrical signals. The transceiver can implement the sending and receiving of signal light with dual wavelengths.
