    Abstract: A tunable optical network unit (ONU) for a multi-wavelength passive optical network (MW PON) system and an operation method thereof are provided. The tunable ONU includes a cyclic tunable filter configured to have cyclic wavelength transmission properties that allow all wavelength channels of both a downstream signal and an upstream signal and to vary a wavelength to pass therethrough; a wavelength splitter configured to split an upstream signal wavelength band and a downstream signal wavelength band; a photodetector element configured to detect a downstream signal that is transmitted through the wavelength splitter, passing through the cyclic tunable filter which is aligned to a specific downstream signal wavelength channel; and a tunable transmitter configured to output to the wavelength transmitter an upstream signal of a wavelength channel that is determined based on an aligned downstream signal wavelength channel of the cyclic tunable filter.

    Abstract: A method of tuning a wavelength in a TWDM-PON which has a plurality of operable channels is provided. First, a second channel is added as an operating channel of the TWDM-PON in which at least a first channel is working, and then an OLT that is providing a service to an ONU through the first channel requests the ONU to tune to the second channel. In response to receiving the request, the ONU determines whether a downstream wavelength of the second channel has been recorded thereon. According to the determination result, the ONU sends to the OLT an ACK message that indicates that the ONU is able to perform wavelength tuning and then commences wavelength tuning to the second channel, or the ONU sends to the OLT a NACK message that indicates that the ONU is unable to perform wavelength tuning.

    Abstract: A burst-mode optical amplification apparatus and method is provided. The burst-mode optical amplification apparatus includes a gain saturation signal generator configured to generate a gain saturation signal for gain stabilization based on an incoming input optical signal; a wavelength multiplexer configured to wavelength multiplex the incoming input optical signal and the gain saturation signal; and an optical amplifier configured to amplify both the wavelength-multiplexed input optical signal and the wavelength-multiplexed gain saturation signal. The apparatus may further include a time delay module configured to synchronize the input optical signal and the gain saturation signal by delaying the transmission time of the input optical signal, taking into consideration the processing time needed by the gain saturation signal generator to generate the gain saturation signal.
