Description

光通訊模組 Optical communication module

本發明係應用於光通訊模組之技術領域，尤指一種具有有效提升組裝公差容忍度的光通訊模組。 The present invention is applied to the technical field of optical communication modules, and particularly refers to an optical communication module with effective enhancement of assembly tolerance tolerance.

一般習知光通訊模組例如大陸已核准專利案第103885140號『芯片陣列與並行光纖被動耦合的光組件及其組裝方法』，請參閱第7圖所示，其係一芯片載體50設有一光電芯片陣列500，且芯片載體50上設有一透鏡本體51及一固定座52，而透鏡本體51內設有一反射面510，且透鏡本體51相對於反射面510之垂直面形成一第一透鏡陣列面511，透鏡本體51相對於反射面510之水平面形成一第二透鏡陣列面512，且固定座52相對於第一透鏡陣列面511位置設有一多路並行光纖520，利用透鏡本體51之反射面510將由經第二透鏡陣列面512的光源平行化，再經由第一透鏡陣列面511聚焦後進入多路並行光纖520。 Commonly known optical communication modules such as the Mainland Approved Patent No. 103885140 "Optical Components of Chip Array and Parallel Optical Fiber Passive Coupling and Their Assembly Method", please refer to FIG. 7, which is a chip carrier 50 with a photoelectric chip array 500, and the chip carrier 50 is provided with a lens body 51 and a fixing seat 52, and the lens body 51 is provided with a reflective surface 510, and a vertical surface of the lens body 51 relative to the reflective surface 510 forms a first lens array surface 511, A second lens array surface 512 is formed on the horizontal surface of the lens body 51 relative to the reflection surface 510, and a multi-channel parallel optical fiber 520 is provided on the fixing base 52 relative to the first lens array surface 511. The reflection surface 510 of the lens body 51 will be formed by The light sources passing through the second lens array surface 512 are parallelized, and then focused through the first lens array surface 511, and then enter the multi-channel parallel optical fiber 520.

當透鏡本體51與固定座52於組裝時如果兩者間第一透鏡陣列511與多路並行光纖520沒有完全對齊，將使光源無法完全進入多路並行光纖520，而降低光通訊模組的效能，即便兩者有對齊，但因光源由第一透鏡陣列511進入多路並行光纖520時，兩者間會因經過空氣而產生部分光源散射，因而降低光通訊模組的效能。 When the lens body 51 and the fixing base 52 are assembled, if the first lens array 511 and the multi-channel parallel optical fiber 520 are not completely aligned between them, the light source will not be able to fully enter the multi-channel parallel optical fiber 520, which reduces the performance of the optical communication module Even if the two are aligned, when the light source enters the multi-channel parallel optical fiber 520 from the first lens array 511, part of the light source will be scattered due to the air passing between the two, thereby reducing the performance of the optical communication module.

The refractive index of the fixing glue ranges from 1.45 to 1.65, at the same time, the light source forms a parallel light source after passing through the collimating lens 124, reflected by the main reflection surface 1221, focused by the focusing lens 23, and then enters the optical fiber 40, because the light source entering the focusing lens 23 is a parallel light source, which can effectively improve the assembly tolerance of the optical system Tolerance can increase the assembly tolerance of the focusing lens 23 and the optical fiber 40 to 0.08mm, and the light source of the light emitting element 311 is parallelized by the collimating lens 124 and enters the lens structure 12, reflected by the main reflection surface 1221, and then exits from the light exit surface 123 After the light is emitted, part of the incident light source is reflected by the light exit surface 123, reflected by the secondary reflection surface 1222 to the light-receiving lens 125, focused, and irradiated on the light detection element 312.
