摘要： Embodiments of the invention describe apparatuses, optical systems, and methods for utilizing a dynamically reconfigurable optical transmitter. A laser array outputs a plurality of laser signals (which may further be modulated based on electrical signals), each of the plurality of laser signals having a wavelength, wherein the wavelength of each of the plurality of laser signals is tunable based on other electrical signals. An optical router receives the plurality of (modulated) laser signals at input ports and outputs the plurality of received (modulated) laser signals to one or more output ports based on the tuned wavelength of each of the plurality of received laser signals. This reconfigurable transmitter enables dynamic bandwidth allocation for multiple destinations via the tuning of the laser wavelengths.

摘要： The direct optical amplifier of the present invention monitors not only a pilot tone signal but also the main signal, and when the pilot tone signal loses relation to the main signal, re-establishes the relation between the level of the pilot tone signal and the average level of the main signal such that the pilot tone signal again functions as the reference light of the main signal. The average level of the true main signal from which a noise component has been eliminated is determined by means of a wavelength analyzer. The average level of the true main signal that has been determined is correlated with the level of a pilot tone signal that is monitored, whereby the pilot tone signal again functions as the reference light of the main signal. The monitored pilot tone signal is then controlled to obtain the desired average level of the true main signal.

摘要： In a light transmission apparatus which controls an optical excitation intensity of an amplifying optical fiber or an attenuation of an optical variable attenuator based on an output light intensity, the output light intensity is sampled. When a change rate of an input light intensity exceeds a threshold value, the optical excitation intensity or the attenuation is controlled based on the output light intensity immediately before the change rate exceeds the threshold value. Accordingly, an occurrence of an optical surge is prevented and it is made possible to output an optical signal free from a signal error or a signal disconnected state.

摘要： Threshold setting apparatus controls a relative relation in DC level between a baseband signal produced by processing a received signal and a threshold for use in identifying serial data from the baseband signal. The apparatus includes a waveform distortion estimating circuit and a setting circuit. The waveform distortion estimating circuit estimates, based on the baseband signal, a relation between the center of the dynamic range of the baseband signal and a crossing point where a positive-going edge curve crosses a negative-going edge curve of an eye pattern formed by the baseband signal. The setting circuit adjustably sets either the threshold or the DC level of the baseband signal in dependence upon the relation estimated by the waveform distortion estimating circuit.

摘要： A controlling apparatus and a controlling method for a wavelength division multiplexing optical amplifier to reduce the controlling error due to noise light included in the monitoring light. The controlling apparatus branches, by a photocoupler, a portion of WDM signal light amplified by a light level controlling part and separates the branched light into groups of even-numbered channel components and odd-numbered channel components using a wavelength channel separate filter. Monitor signals corresponding to the light powers of the even-numbered group and odd-numbered group, respectively, are generated by respective photoelectric converting parts and LPF's. One of the monitor signals, which corresponds to one of the even-numbered group and the odd-numbered group, is selected by a monitor signal selecting/controlling part and then sent to a comparator. The control apparatus conducts feedback controlling in accordance with the output signal of the comparator, so that the light level controlling part conducts to ALC (automatic level control) operate.

摘要： A delay circuit delays an input signal. Further, a level shift circuit, which has a variable level shift amount, is provided between the delay circuit and an OR circuit, thereby making it possible to adjust a time during which a logic of active of the delayed signal is kept. Moreover, the OR circuit performs an OR operation of the input signal and an output signal of the level shift circuit so as to obtain a signal of an OR logic, which drives a light emitting element. With this arrangement, the level shift amount is adjusted in response to a control signal externally supplied, in an optical transmitter arranged such that the input signal and output light emitted from the light emitting element with a delay in the emission, have the equal duty ratio. In this way, property unevenness among finished products of the light emitting element is cancelled out. Thus, it is possible to drive the light emitting element at a higher speed.
