A photoelectric converter and a photoelectric connection device are provided. The photoelectric converter comprises a housing, wherein a driving controller, at least one information transmitting chip and at least one information receiving chip are provided on a substrate in the housing. The information transmitting chip, under the control of the driving controller, converts an electrical signal to be transmitted to an optical signal and transmits the optical signal through an optical fiber corresponding to the information transmitting chip. The information receiving chip, under the control of the driving controller, converts an external input optical signal that has reached a receiving surface of the information receiving chip to an electrical signal and outputs the electrical signal, wherein the external input optical signal is transmitted through an optical fiber corresponding to the information receiving chip. Information transmitting chips and information receiving chips are provided in the same photoelectric converter, each information transmitting chip transmitting information through a corresponding optical fiber and each information receiving chip receiving information through a corresponding optical fiber, thus multichannel optical fiber transmission can be integrally achieved.
