摘要： In an optical transmission apparatus, an optical-to-electrical converter converts a received optical signal into an electrical signal, and an amplifier amplifies the resulting electrical signal. A plurality of analog-to-digital converters then convert the amplified electrical signal from analog form to digital form in a time-interleaved manner to produce digital outputs. When correcting the analog-to-digital converters, a controller varies the gain of the amplifier in such a way that a total amplitude or an average amplitude indicated by the digital outputs of the analog-to-digital converters will be equal to or greater than a specified threshold.

摘要： Optical add/drop nodes are used in a network having a pair of optical transmission paths for transmitting optical signals in opposite directions to each other. Each add/drop node comprises a variable split ratio optical coupler for splitting an optical signal output from a transmitter. The split ratio of the variable split ratio optical coupler is set such that the optical power levels of the signals added through the respective optical add/drop nodes are equal to one another respectively on the pair of optical transmission paths.

摘要： In an optical transmission system, a transmitting transceiving node generates a multiplexed optical-packet signal by performing optical wavelength multiplexing on a plurality of optical packets, and transmits the multiplexed optical-packet signal to a receiving transceiving node. The receiving transceiving node transmits the multiplexed optical-packet signal back to the transmitting transceiving node. The transmitting transceiving node detects a skew amount of the optical packet allocated to each wavelength band of the multiplexed optical-packet signal received from the receiving transceiving node, and adjusts a delay amount of the optical packet based on the detected skew amount.

摘要： Each of a plurality of semiconductor optical amplifiers operates as an optical gate switch and selects an optical signal indicated by a gate control signal from an optical gate switch control unit. A plurality of photodetectors monitor the power of an optical signal input through a corresponding input port. A VOA control unit calculates an amount of attenuation corresponding to each input port based on the power of each optical signal. A variable optical attenuator attenuates the selected optical signal according to the calculated amount of attenuation in synchronization with the gate control signal.

摘要： An optical network system capable of directly routing optical signals without entailing multiple reception of identical wavelengths. A set wavelength output unit outputs a set wavelength. An Nk-axis filter receives an Nk-axis signal propagated through a ring of an Nk-axis direction and an Nk−1-axis signal split inside the local node, and performs filtering by removing a wavelength identical with that of the Nk−1-axis signal from the Nk-axis signal and adding the wavelength of the Nk−1-axis signal to the Nk-axis signal. An Nk-axis splitter splits the Nk-axis signal into two, one being output to outside through the ring of the Nk-axis direction while the other being output, if k
