Abstract

The invention discloses a passive optical network system, which includes several optical network units, data buffers are connected between any two optical network units, each optical network unit is connected with several optical distribution units, and each optical distribution unit The units are respectively connected to several first optical fiber line terminal units through the first wavelength division multiplexing unit, and each optical network unit is connected to a second optical fiber line terminal unit through the second wavelength division multiplexing unit, and the second optical fiber line terminal unit Priority is higher than the first optical line termination unit. The invention can improve the deficiencies of the prior art, improve the utilization rate of the original network hardware, thereby improving the data transmission efficiency in the passive optical network.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to a passive optical network system and a communication method thereof. Background technique [0002] With the development of optical fiber network communication, passive optical network has been more and more used in various communication networks due to its advantages of low cost, high bandwidth, and strong scalability. Chinese invention patent CN 102572619B discloses a passive optical network system, which improves the transmission efficiency of the optical communication network. However, since it improves the efficiency by increasing the management link between the optical fiber line terminal unit and the optical distribution unit, it has a strong dependence on the hardware (the number of optical distribution units must be adequately guaranteed), so in the actual use environment More restrictive. Contents of the invention [0003] The technical problem to...
