Abstract

The invention relates to an optical transceiver component for parallel transmission. One end of a printed circuit board is provided with an electrical signal input port; a VCSEL (Vertical Cavity Surface Emitting Laser) array and a PD (photoelectric detector) array are assembled on the printed circuit board; a laser driving chip and a detector TIA chip are assembled on an electrode on the surface of the printed circuit board; the VCSEL array and the PD array are respectively connected with the laser driving chip and the detector TIA chip; an optical lens group comprises a reflector and two lens arrays; the two lens arrays are respectively placed on the lower end and the front end of the optical lens group; the lenses are mutually vertical in the axial direction; each lens in the first lens array is directed at the centers of the effective regions of the VCSEL array and the PD array in a one-to-one way; each lens in the second lens array is respectively directed at the first lens array in the one-to-one way; and the reflector is arranged at the crossing point of optical axes of the two lens arrays at an inclination angle of 45 DEG. The optical transceiver component provided by the invention has high alignment accuracy and is suitable for a pluggable parallel optical transceiver component.

Description

technical field [0001] The invention relates to an optical transceiver component for parallel transmission. Background technique [0002] With the rapid development of optical communication, there have been many related studies on the alignment coupling of lasers or detectors and optical channels in optical fiber communication. Most products are based on a single laser aligned to a single fiber, such as SFP optical transceivers, with a well-positioned transmit module and a receive module, each with a single fiber in the LC connector housing. [0003] However, with the rapid growth of human's demand for communication bandwidth, existing communication systems are facing two challenges of capacity and energy consumption. Due to the need to provide greater bandwidth in a smaller space and lower power consumption, the research and development of parallel optical modules has begun to increase. Parallel optical modules are multiple lasers aligned with multiple optical fibers in a...
