Abstract: Disclosed is a multiwavelength locking method and apparatus using an acousto-optic tunable filter in an optical communication system including optical transport networks, in which output wavelengths of light sources are monitored under the condition in which pilot signals are applied to the acousto-optic tunable filter, so as to lock the wavelengths of the light sources, thereby eliminating an wavelength instability of the light sources for an improvement in transmission characteristics. The acousto-optic tunable filter receives light beams of N different frequencies respectively outputted from N light sources, along with N pilot signals having different frequencies, and converts respective frequencies of beam components of the output beam corresponding to the N pilot signals, thereby outputting N frequency-converted output beams to be applied to a photo-detector. N electrical signals respectively corresponding to the frequencies of the pilot signals are outputted from the photo-detector, separated from one another while corresponding to the light sources, respectively, and then used to compensate for respective output wavelengths of the light sources, thereby enabling the corresponding light sources to output locked wavelengths, respectively.

Abstract: Disclosed is a clock phase aligning apparatus capable of synchronizing a clock signal in the middle of an upstream burst mode data bit in an optical line terminal of a passive optical network. The clock phase aligning apparatus effectively aligns a phase of a clock signal with a phase of data during an overhead period of burst mode packet data through an over-sampling scheme and a digital scheme. Burst mode data signals are subject to an over-sampling through a high speed continuous mode analog circuit and then converted into low speed parallel signals through a parallel conversion unit. Such low speed parallel signals are processed with respect to sampling patterns through a digital look-up scheme in a logic circuit device such that the phase of data is arranged with the phase of a clock signal during a limited bit stream specified in a burst mode preamble timing.
