Optical component, optical module, and communications device

An optical module, wherein the optical module comprises a light splitting structure, a first filter, and a collimation lens;

• wherein a light splitting surface of the first filter is disposed in a direction facing a light inlet and outlet, the light inlet and outlet is configured to pass optical signals, and a first optical signal on a first path is incident on the light splitting surface of the first filter through the light inlet and outlet;
• wherein the light splitting surface of the first filter reflects the first optical signal to the collimation lens along a second path, wherein the first path does not coincide with the second path, wherein the collimation lens is disposed on the second path, wherein the first optical signal reflected by the first filter to the collimation lens comprises at least two non-parallel lights, and the collimation lens is configured to convert the at least two non-parallel lights on the second path into at least two parallel lights;
• and
• wherein the first optical signal has at least one type of wavelength, 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 the light splitting structure is configured to output, based on a wavelength type, the first optical signal adjusted by the collimation lens.
