摘要： Provided is a pre-equalization optical transmitter capable of generating a pre-equalized RZ-type optical signal with a simple and low-cost structure. Further provided is a pre-equalization optical fiber transmission system in which dispersion is appropriately managed by using the pre-equalization optical transmitter. The pre-equalization optical transmitter includes: an RZ conversion circuit (11) for generating an RZ-type input data sequence based on an NRZ-type input data sequence (D (t)) and a clock (p (t)) that is twice the speed of the NRZ-type input data sequence; a digital filter (12) for generating pre-equalized data by a convolution operation between the RZ-type input data sequence and a desired transfer function corresponding to the wavelength dispersion of an optical fiber transmission path; D/A converters (13a, 13b) for performing D/A conversion on the pre-equalized data to output analog pre-equalized data; and a vector modulator (15) for modulating light from a laser light source (14) based on the analog pre-equalized data to output an RZ-type optical signal.

摘要： A phase shift unit (12) provides a prescribed phase difference (π/2, for example) between a pair of optical signals transmitted via a pair of arms constituting a data modulation unit (20). A low-frequency signal f 0 is superimposed on one of the optical signals. A signal of which phase is shifted by π/2 from the low-frequency signal f 0 is superimposed on the other optical signal. A pair of the optical signals is coupled, and a part of which is converted into an electrical signal by a photodiode (3). 2f 0 component contained in the electrical signal is extracted. Bias voltage provided to the phase shift unit (12) is controlled by feedback control so that the 2f 0 component becomes the minimum.

摘要： A system and method for generating an optical return-to-zero signal. The system includes an electro-optical conversion system. The electro-optical conversion system is configured to receive an input electrical non-return-to-zero signal, process information associated with the input electrical non-return-to-zero signal, and generate a first electrical signal and a second electrical signal based on at least information associated with the input electrical non-return-to-zero signal. Additionally, the electro-optical conversion system is configured to delay a second electrical signal with respect to the first electrical signal by a predetermined period of time, process information associated with the first electrical signal and the delayed second electrical signal, and generate an output optical return-to-zero signal based on at least information associated with the first electrical signal and the delayed second electrical signal. The output optical return-to-zero signal is an optical differential return-to-zero signal, and the output optical return-to-zero signal is substantially free from any frequency chirp.
