Optical fiber connector
View Patent ↗An optical fiber connector includes a circular polarizer, an optical electrical converter, and a transceiving module. The circular polarizer receives external optical signals from an optical fiber and divides the received optical signals into first optical signals and second optical signals. The optical electrical converter converts the first optical signals into first electrical signals. The transceiving module receives third electrical signals from ports of an optical communication device, and includes an optical electrical converting circuit and an electrical optical converting circuit. The optical electrical converting circuit converts the second optical signals into second electrical signals and transmits the second electrical signals to the optical communication device. The electrical optical converting circuit converts the third electrical signals into third optical signals and transmits the third optical signals to the optical fiber. The first electrical signals are used to drive the transceiving module.
