The invention discloses a front-back snap ring type smart tag connector for communication. A plastic seat is provided with an accommodating slot on the upper end face. A first connecting port and a second connecting port are respectively connected with a smart tag and a control line. The connector further includes an LED chip. The plastic seat is internally provided with an inserting position communicated with the accommodating slot, and the LED chip is inserted into the inserting position. The connector further includes a terminal component embedded into the accommodating slot. A contact terminal and a contact portion connected with the smart tag and the control line protrude from two opposite side ends of the terminal component respectively. Front and back snap rings are directly clamped and fixed to the upper end of an optical fiber adapter and are beyond the upper end of the adapter by only a small distance, so that the connector is not constrained by the space and structure of a fusing and wiring plate during installation and can adapt to multiple types of fusing and wiring plates. However, in order to weld the original smart connector onto a circuit board, there is a need to customize circuit boards according to fusing and wiring plates of different types. Thus, cost and time are saved.
