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： A key management device and method which is required for provision of a security service in an EPON vulnerable to security breaches due to characteristics of Ethernet. A session key distribution function is performed in such a manner that, during the process of communication setup between an OLT and an ONU, the OLT multicasts a public key and the ONU receives the public key from the OLT and then distributes a corresponding session key to the OLT. A session key update function is performed in such a manner that an existing session key is updated with a new one through a periodic MPCP general gate message and an ONU report message.
