Embodiment Construction
[0019] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0020] figure 1 It is a structural block diagram of an ONU terminal according to an embodiment of the present invention. like figure 1 The shown ONU terminal includes: one or more serial ports 10; PON module 14; 10 to transfer data between.
[0021] Through the above-mentioned terminal, the serial port passive optical network device connection is realized, and the optical communication bearer of the serial port is realized. Passive optical network equipment has the advantages of long transmission distance, low interference of optical communication, and large bandwidth. These advantages are introduced through the above-mentioned terminal, which has certain advantages compared with traditional seri...
