REMOTE NODE DEVICE, OPTICAL NETWORK UNIT AND SYSTEM AND COMMUNICATION METHOD THEREOF |
摘要 |
The invention relates to a remote node device, optical network unit and system and communication method thereof. A remote node device for mutual communication between optical network units in a passive optical network according to the invention includes: an NxN-arrayed waveguide grating configured to receive upstream optical signal of one of the optical network units and to output it as a first optical signal; a 1x2 wavelength division multiplexer configured to separate per band the first optical signal to obtain a second optical signal; and a lx(N-l) power distributor configured to transmit the second optical signal to the corresponding optical network unit through the NxN-arrayed waveguide grating. With the inventive solution, mutual communication between optical network units can be enabled through a remote node device alone simply by structurally modifying the remote node device and the optical network units without modifying a conventional optical line terminal, and an optical signal for communication will not undergo the optical to electronic to optical conversion process thereby greatly lowering delay in communication. |
