具有抗干扰性能的光收发一体组件及BOB光模块
摘要：
本发明公开了一种具有抗干扰性能的光收发一体组件及BOB光模块，其包括BOSA壳体、ROSA结构和导体接地结构；BOSA壳体包括BOSA方形外套、TOSA结构和尾纤结构，TOSA结构组设于所述BOSA方形外套一端，且所述TOSA结构的TOSA电路板用于组设于PCB板上；尾纤结构组设于所述BOSA方形外套另一端；ROSA结构一端组设于所述BOSA方形外套底壁，另一端用于组设于所述PCB板上；导体接地结构位于所述ROSA结构外侧，并用于将所述BOSA壳体上的感应辐射电流导引至所述PCB板地平面上。本发明保证抗干扰性能的同时，既解决了使用外部屏蔽罩导致PCB板面积偏大的问题，也避免更改BOSA组件内部结构。
摘要（英）：

The invention discloses an optical transmitting-receiving integrated assembly with anti-interference performance and a BOB optical module. The assembly comprises a BOSA shell, an ROSA structure and aconductor grounding structure. The BOSA shell comprises a BOSA square outer sleeve, a TOSA structure and a tail fiber structure, the TOSA structure is assembled at one end of the BOSA square outer sleeve, and a TOSA circuit board of the TOSA structure is assembled on a PCB; the tail fiber structure is assembled at the other end of the BOSA square outer sleeve; one end of the ROSA structure is assembled on the bottom wall of the BOSA square outer sleeve, and the other end of the ROSA structure is assembled on the PCB; and the conductor grounding structure is located at the outer side of the ROSA structure and is used for guiding an induced radiation current on the BOSA shell to the ground of the PCB. The anti-interference performance is guaranteed, the problem that the area of the PCB is large due to the fact that an external shielding cover is used is solved, and the internal structure of the BOSA assembly is prevented from being changed.
