Abstract

The invention relates to the technical field of optical communication and particularly relates to a single-fiber bidirectional optical module. The optical module comprises a control end, a packaging shell, a transmitting assembly and a receiving assembly, wherein the transmitting assembly and the receiving assembly are arranged in the packaging shell, the control end is used for controlling the transmitting assembly and the receiving assembly to work; the transmitting assembly comprises a laser and a first beam splitter, and the first beam splitter is used for transmitting light emitted from the laser to the optical fiber port; the receiving assembly comprises a second beam splitter and an optical detection chip, the first beam splitter is used for reflecting the light transmitted from the optical fiber port to the second beam splitter, and the second beam splitter is used for reflecting the light reflected by the first beam splitter to the optical detection chip. The optical module is advantaged in that the first beam splitter is used for transmitting light emitted from the laser to an optical fiber port. External light is transmitted into the receiving assembly through the optical fiber port, the first beam splitter of the transmitting assembly reflects the external light to the second beam splitter of the receiving assembly, the second beam splitter further reflects the reflected light to an optical detection chip, and the optical module achieves single-fiber two-way.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a single-fiber bidirectional optical module. Background technique [0002] Optical communication single-fiber bidirectional technology refers to transmitting and receiving two central wavelengths in different directions, and using WDM technology to realize bidirectional transmission of optical signals on one optical fiber. Traditional optical modules generally have two ports: a transmitting port (TX) and a receiving port (RX), while a single-fiber bidirectional module has only one port, which can be filtered by the filter in the optical module, and at the same time complete the transmission of a wavelength optical signal emission and reception of another wavelength optical signal. Compared with the dual-fiber bidirectional optical module, the single-fiber bidirectional optical module can effectively reduce the number of optical fibers, save the cost of optical fibe...
