Abstract:
1. An apparatus for transceiving packets in a wavelength division multiplexing-passive optical network (WDM-PON), the apparatus comprising: a downstream code perceiving part perceiving an idle code from a downstream data frame to be transmitted to an optical network terminal (ONT); a trailer transmitting control part receiving an idle code perceiving signal from the downstream code perceiving part and forming a downstream trailer of the downstream data frame by adding an overhead for a reception control of the downstream data frame by the ONT and a transmission control of an upstream data frame to be loop-back transmitted from the ONT; an upstream code perceiving part receiving and perceiving an upstream trailer of the loop-back transmitted upstream data frame; and a trailer receiving control part controlling a receiving of the upstream data frame after receiving overhead information, which is added by the ONT, for a receiving control of the upstream data frame from the upstream code perceiving part.
