Embodiment Construction
[0043] The basic idea of the present invention is: on the basis of the existing passive optical network, some active and passive optical functional modules are added, so that when an uncontrollable long-emitting optical network unit occurs, the optical line terminal and the normal On the premise that the communication between the optical network units remains unimpeded, timely isolate the optical network units that emit light abnormally.
[0044] figure 2 It is a schematic structural diagram of the fault isolation system for abnormal light emission of the optical network unit of the present invention, such as figure 2 As shown, the optical network unit abnormal lighting fault isolation system of the present invention includes: optical line terminal 201, long-lighting optical network unit isolator 202, wavelength division multiplexing coupler 203, wavelength selective coupler 204, branch fiber selector 205, optical splitter device 206, optical selection router 207 and opti...
