Abstract: An optical-isolation apparatus of an optical-fiber connector is mainly applied in the optical transmission apparatus and the optical receiving module of the optical-fiber connector to isolate the optical transmission apparatus and the optical receiving module to prevent optical and electrical influences therebetween. Two electrically-conductive shells respectively cover the optical transmission apparatus and the optical receiving module of the optical-fiber connector. The front end of the electrically-conductive shell is set with an opening, and a pin is extended out from the electrical-conducting shell at the bottom portion. By the aforementioned composition of devices, the optical-isolation apparatus of the optical-fiber connector is formed.
