Abstract

The invention relates to a parallel optical transceiving component for high-speed transmission. An electrical signal input port is formed at one end of a circuit board; a vertical cavity surface emitting laser (VCSEL) array and a photoelectric detector (PD) array are arranged on a substrate and are connected with a conductive golden wire in a routing way; the substrate is fixed on a printed circuit board and is connected with the printed circuit board in a routing way; a laser driving chip and a detector totally integrated automation (TIA) chip are arranged on electrodes on the surface of the printed circuit board; an optical lens group comprises a reflector and two groups of lens arrays; the first group of lens arrays and the second group of lens arrays are arranged at the lower end and the front end of the optical lens group respectively; the lens are axially perpendicular mutually; all the lenses in the first group of lens arrays are aligned with effective regional centers of the VCSEL laser array and the PD array one by one; all the lenses in the second group of lens arrays are aligned with the first group of lens arrays one by one respectively; and the reflector is arranged at the joint of optical axes of the two groups of lens arrays at the inclined angle of 45 DEG. The parallel optical transceiving component has high aligning precision and is suitable for parallel optical transceiving modules capable of being inserted and pulled out.

Description

technical field [0001] The invention relates to a parallel optical transceiver component for high-speed 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 f...
