Abstract
The invention provides a light emitting device and a light transceiving module. Multiple paths of light beams emitted by a laser assembly in a light emitting device are input into a first light path conversion assembly to be converted into multiple paths of collimated light, the multiple paths of collimated light are input into a z-block assembly to be combined into one path of collimated light, and the path of collimated light is input into a second light path conversion assembly to be bent by 180 degrees and then output and coupled into a collimator assembly; the collimator assembly comprises a collimator and a first connector, and the first connector is connected with the collimator through a first optical fiber. According to the light emitting device, the collimator assembly and otherelements of the light emitting device are arranged in a layered mode, the space utilization rate of the light device in the direction perpendicular to the light path is increased, meanwhile, the length of the light emitting device is reduced, the structure is more compact, and the requirement for circuit board layout is met. And the collimator is flexibly connected with the first connector, so that the problem of optical port alignment precision is solved, and enough space is provided for placement of the first optical fiber.
Description
technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical emitting device and an optical transceiver module. Background technique [0002] Optical modules are gradually evolving from 100Gbps to 400Gbps. IEEE and many MSA organizations have formulated PMD and module packaging standards for 400G optical modules in various application scenarios. The PMD layer adopts single-wavelength 100Gb / s PAM4, and QSFP-DD package or OSFP package is the mainstream packaging technology for 400G optical modules. Compared with the 100G optical module, the circuit of the 400G optical module is more complex, and requires a digital signal processor for signal processing, and various auxiliary circuits, and requires a larger space when the circuit board is laid out; but the volume of the 400G optical module after packaging The standard has not been increased, which requires compressing the size of the light emitting component and the ...
