摘要： The present invention relates to none return to zero (NRZ) modulation method. The NRZ optical modulation is performed by combining a clock signal and NRZ data at a sending end and signal distortion capable of being generated when the clock signal and the NRZ data are combined is optimized by controlling the magnitude and phase of the clock signal. At the receiving end, the clock signal is extracted by performing narrow band band-pass filtering of the detected optical signal transmitted from a transmitter and data is recovered using the clock signal. Therefore, a receiver structure for clock extraction is simpler, an error rate of data recovery is lower by clearly extracting the clock signal, and transmission distance of the optical signal is longer.

摘要： An apparatus and method for monitoring an optical signal are provided. In the apparatus, a polarization adjusting unit converts the state of polarization of an optical signal. A polarization beam splitter splits the optical signal into a first polarization component and a second polarization component perpendicular to each other. An optical intensity measuring unit measures the optical intensity of the first polarization component. A feedback control unit controls the polarization adjusting unit so that the first and second polarization components are aligned to the two axes of the polarization beam splitter. A scrambler scrambles the optical signal input to the transmission optical fiber. According to the apparatus and method, optical signal-to-noise ratio (OSNR) can be measured accurately.

摘要： Provided are an operation circuit for a modified Euclidean algorithm in a high-speed Reed-Solomon (RS) decoder and a method of implementing the modified Euclidean algorithm. Since a finite state machine (FSM) for generating a stop signal and an FSM for generating a control signal that controls a swap operation, a shift operation, and a polynomial operation for each basic cell of the modified Euclidean algorithm are used, an area-efficient RS decoder can be realized without using a conventional degree computation unit for comparing and calculating degrees.

摘要： An apparatus for generating a Carrier-Suppressed Return-to-Zero (CS-RZ) signal is disclosed. The apparatus includes a mixer, a Low Pass Filter (LPF), a driver amplifier and a single external modulator. The mixer generates a modulator input by mixing data with a half clock signal. The LPF band-limits the modulator input data into low frequency band data. The driver amplifier amplifies the modulator input data generated by the mixing of the mixer and the band-limiting of the LPF. The external modulator generates CS-RZ signal, in which the phases of adjacent pulses have been inverted, by applying bias voltage to the modulator input data to be placed at the null point of the transfer function of the external modulator.
