A transmitter optical sub-assembly, includes 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. An optical transceiver assembly includes the transmitter optical sub-assembly, and has comparatively small reflection and a comparatively small return loss of an optical fiber end face.

Transmitter optical sub-assembly and optical transceiver assembly

Embodiments of the present invention disclose an optical signal transmission method, apparatus, and system. The apparatus includes a short wavelength division multiplexer, a signal processor, a first linear driver, a second linear driver, a first transmitter, and a second transmitter. The signal processor is configured to perform bit rate allocation and code pattern modulation on a received binary signal, to obtain a first electrical signal to be sent to the first linear driver and a second electrical signal to be sent to the second linear driver. It can be learnt that, by implementing the embodiments of the present invention, a quantity of wavelengths transmitted in a multimode optical fiber can be reduced by performing bit rate allocation on a binary signal, thereby reducing interference between channels in the optical fiber for optical signal transmission.
