1. An optical component comprising: a light splitting structure, a first filter, a connecting pipe body, a first optical receiver, a second optical receiver, 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 first optical signal comprises a first-wavelength optical signal and a second-wavelength optical signal, the first-wavelength optical signal and the second-wavelength optical signal have different wavelengths;
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 the first-wavelength optical signal and the second-wavelength optical signal that are two non-parallel lights, and the collimation lens is configured to convert the first-wavelength optical signal and the second-wavelength optical signal as two parallel lights; and
wherein the light splitting structure is disposed on an emergent path of the two parallel lights, and wherein the light splitting structure is configured to output the two parallel lights to be received by the first optical receiver and the second optical receiver disposed in parallel on a shell of the connecting pipe body.
