Mini optical transceiver

The utility model relates to a mini optical transceiver which comprises a base, a rigid flexible printed circuit board, a light emission sub module and a light reception sub module. The rigid flexible printed circuit board is bent to form an optical device area with the base, and the light emission sub module and the light reception sub module are installed in the optical device area. Due to the rigid flexible printed circuit board, the optical transceiver changes a traditional plane design concept, expands to three-dimensional space concept, utilizes available space in a maximum mode, reduces occupancy and achieves mini design. In addition, the optical device area enables a module to be compact in structure. Thus, the size and the weight of the module are greatly reduced. The mini optical transceiver is convenient to install and use and facilitates system integration.
