Abstract

The present application provides an ONU and a remote node for supporting the inter-ONU internetworking. An ONU transmitter for supporting the inter-ONU internetworking in a system comprising a plurality of PONs each having a corresponding upstream/downstream wavelength comprises: a delay line configured to delay inter-ONU data to be transmitted with respect to upstream data to be transmitted, wherein the inter-ONU data refers to data to be transmitted by the ONU to another ONU, and the upstream data refers to data to be transmitted by the ONU to an OLT; a combiner configured to combine the upstream data and the delayed inter-ONU data; and a wavelength tunable laser source configured to generate optical signals with different wavelengths to modulate the upstream data and the inter-ONU data received by the combiner, respectively.
