Abstract: An integrally formed coupling module is provided. In the module, a total internal reflective surface reflects a first optical signal emitted by a laser to form a second optical signal, the second optical signal is output to the medium air interface, a medium air interface refracts the second optical signal to form a third optical signal, the third optical signal is output from air to the air medium interface, an air medium interface refracts the third optical signal to form a fourth optical signal, and then the fourth optical signal is output to an optical fiber. In addition, a refractive angle at which the medium air interface performs refraction to form the third optical signal is equal to an incidence angle at which the third optical signal is output to the air medium interface, and a first incident surface and a second incident surface are mutually perpendicular in space.

Abstract: Embodiments of the present application disclose a transmitter optical sub-assembly, including a prism body, a first lens, and a plug-in. The prism body includes a light inlet end and a light outlet end, the first lens is disposed between the light outlet end and the plug-in, and the plug-in includes a contact end. The contact end is located on a surface that is of the plug-in and that is away from the first lens, a center of the contact end is located on a focus on an optical path of the first lens, and the contact end is arc-shaped for a purpose of a gapless interconnection with an optical fiber, to reduce end face reflection of the contact end. The present application further discloses an optical transceiver assembly. The transmitter optical sub-assembly has comparatively small reflection and a comparatively small return loss of an optical fiber end face.
