Provided is a bidirectional WDM-PON. The bidirectional WDM-PON includes an optical comb generator, an amplifier, an optical de-interleaver, a downstream signal generator, an upstream signal generator, an upper circulator, and a lower circulator. The optical comb generator generates multi-wavelength light. The amplifier amplifies the multi-wavelength light. The optical de-interleaver receives the amplified multi-wavelength light to divide the received light into an odd wavelength train and an even wavelength train, and outputs the odd and even wavelength trains. The downstream signal generator receives the odd wavelength train to generate a downstream signal. The upstream signal receiver receives an upstream signal. The upper circulator determines a delivery path of the odd wavelength train and the downstream signal. The lower circulator determines a delivery path of the even wavelength train and the upstream signal. |
