摘要： Disclosed are an apparatus and method for detecting optical signals. The optical signal detection apparatus includes: a signal receiver to convert a received optical signal into an electrical signal; a threshold decision unit to establish a mathematical model based on the electrical signal and to decide an optimized threshold value based on the mathematical model; and a signal detector to detect the electrical signal based on the optimized threshold value. Hence, since threshold values optimized adaptively according to received signals are used, a bit error rate may be lowered and accordingly detection performance may be improved.

摘要： Disclosed are an optical transmission apparatus and method in a wavelength division multiplexing passive optical network (WDM-PON). The optical transmission apparatus outputs an optical signal by applying a DC bias current and an RF signal to a laser diode at a threshold current level of the laser diode, thereby broadening an optical spectrum of the laser diode. Accordingly, an optical link becomes less vulnerable to reflection induced noise, which contributes to improve stability and reliability of the optical link.

摘要： Provided is an apparatus for connecting a wavelength division multiplexing passive optical network (WDM-PON) to a time division multiplexing passive optical network (TDM-PON). In a hybrid, passive optical network which is a combination of the WDM-PON and the TDM-PON, the apparatus is formed at a subscriber side for matching the WDM-PPN and the TDM-PON. Accordingly, a passive remote mode can be implemented as a passive node not an active node. Therefore, the entire optical network can be efficiently operated. In addition, since the apparatus located on the subscriber side uses a wavelength-tunable light source, any dependency on the wavelength of a WDM-PON optical signal is removed.

摘要： The present invention provides a wavelength converting apparatus and optical cross connect system using the same. The wavelength converting apparatus includes a plurality of optical sources of fixed wavelengths, a switching means, and at least one wavelength converting means. The optical sources with fixed wavelengths provide probe beams with fixed wavelengths, the wavelength being different from each other. The switching means selects at least one beam of a wavelength corresponding to a wavelength conversion request of a transmission signal among a plurality of beams inputted from the fixed-wavelength light sources, and provides the selected beam as a probe beam. The wavelength converting means receives the transmission signal and the probe beam from the switching means, and converts a wavelength of the inputted transmission signal through cross gain modulation, cross phase modulation or optical-to-electrical-to-optical (O/E/O) conversion of the transmission signals and the probe beams.
