Traditional fiber optic signal transmission devices are usually one-way transmission, that is, optical signals are sent from the transmitting end, transmitted through the optical fiber, and then converted into electrical signals at the receiving end. This traditional device is usually used in long-distance communication, data transmission, network connection and other fields. It has the advantages of fast transmission speed, strong anti-interference ability and high security. However, there are some disadvantages in traditional fiber optic signal transmission devices:
