Embodiment Construction
[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] see figure 2 , which is the basic interface diagram of the present invention. For the radio frequency remote equipment at the antenna port, while completing the radio frequency processing and analog-to-digital conversion, the digital electrical signal is obtained according to a certain protocol and sent to the twisted pair. The electrical signal may be a high-speed electrical signal or a low-speed electrical signal, without limitation. After the conversion device receives the electrical signal sent from the twisted pair, it performs multiplexing / demultiplexing or digital combining / distribution processing on the signal, and then performs photoelectric conversion on the processed electrical signal according to a certain format, and will get The optical signal is sent to the near-end processing device unit through the optical f...
