REMOTE NODE DEVICE, OPTICAL NETWORK UNIT AND SYSTEM AND COMMUNICATION METHOD THEREOF |
摘要 |
A remote node device for mutual communication between optical network units in a passive optical network includes an N×N-arrayed waveguide grating configured to receive upstream optical signal of one of the optical network units and to output this signal as a first optical signal; a 1×2 wavelength division multiplexer configured to separate per band the first optical signal to obtain a second optical signal; and a 1×(N−1) power distributor configured to transmit the second optical signal to the corresponding optical network unit through the N×N-arrayed waveguide grating. |
