An optical fiber connector and cable having a transducer and a receiver for optical transmission is provided. The optical fiber connector includes an optical fiber cable, and first and second connectors. The first connector has a transducer for controlling data transmission, and is connected to one end of the optical fiber cable. The second connector has a receiver for controlling data reception, and is connected to the other end of the optical fiber cable. The first and second connectors are inserted into coaxial cable connectors which are respectively connected to an external transmission interface unit and an external reception interface unit. According to the connector and cable, a transducer and a receiver which are used for optical fiber cable transmission are installed in a connector of an optical fiber cable. Therefore, the connector and optical cable are compatible with digital data transmission systems which exclusively use a coaxial cable. Further, an interface system between a computer and multiple peripheral apparatus uses an optical fiber cable rather than a coaxial cable as a transmission cable, so that the data transmission speed and the performance can be improved.
