Abstract:
1. An optical module comprising: a first optical element for reflecting an optical signal of a first wavelength component and transmitting an optical signal of second and third wavelength components; a first light receiving subassembly, optically coupled to the first optical element, provided to receive the optical signal of the first wavelength component; a second optical element for reflecting the optical signal of the second wavelength component and transmitting the optical signal of the third wavelength component; a second light receiving subassembly, optically coupled to the second optical element, provided to receive the optical signal of the second wavelength component; a light emitting subassembly, optically coupled to the second optical element, provided to generate the optical signal of the third wavelength component; an optical joint sleeve having a first mount surface to mount the first optical element and a second mount surface to mount the second optical element, wherein the first mount surface is a bottom surface of a first groove and the second mount surface is a bottom surface of a second groove that intersects the first groove; and a light transmitting part optically coupled to the first optical element, wherein the light emitting subassembly, the first optical element, the second optical element, and the first light receiving subassembly are arranged along a first predetermined plane, and the light emitting subassembly, the first optical element, the second optical element, and the second light receiving subassembly are arranged along a second predetermined plane intersecting at a predetermined angle with the predetermined plane.
