Document Type and Number:
Japanese Patent JP7294761
Kind Code:
B2
Abstract:
This application provides an optical component, an optical module, and a communications device, including a base and a light splitting structure, a first filter, and a collimation lens that are disposed on the base, where a first optical signal on a first path is incident on a light splitting surface of the first filter through a light inlet/outlet; the light splitting surface of the first filter reflects the first optical signal to the collimation lens along a second path, where the collimation lens disposed on the second path is configured to convert the first optical signal on the second path into parallel light; and the first optical signal includes a signal of at least one type of wavelength, and the light splitting structure is disposed on an emergent path of the first optical signal after the first optical signal passes through the collimation lens, and is configured to output, based on the wavelength type, the first optical signal adjusted by the collimation lens. In this application, after a plug-in end sends the first optical signal, the first filter is disposed to directly separate at least two optical signals included in the first optical signal from a main optical path. This avoids a complex optical component structure caused when the first-wavelength optical signal and the second-wavelength optical signal that are included in the first optical signal are separated from the main optical path.
