摘要： An optical transmitter of CS-RZ modulation for further increase the SPM-GVD resistance and an optical fiber transmission system having the same are disclosed. The optical transmitter comprises a carrier source, a data modulating section for intensity-modulating the carrier with a data signal, a clock modulating section for amplitude-modulating the carrier so that the phase of the carrier is inverted for every one-bit slot of the data signal. The optical transmitter is characterized in that the carrier is given a prechirp by the carrier source or the data modulating section.

摘要： The invention provides a technique for optimizing transmission conditions to achieve large-capacity transmission, and also provides peripheral techniques for the practical implementation of optical multiplexing that makes large-capacity transmission possible. A transmission characteristic is measured in a transmission characteristic measuring section (53), and control of signal light wavelength in a tunable light source (44), control of the amount of prechirping, control of the amount of dispersion compensation, and/or control of optical power are performed to achieve the best transmission characteristic. Wavelength dispersion is deliberately introduced by a dispersion compensator, to reduce nonlinear effects. A tunable laser is used to optimize signal light wavelength for each optical amplification repeater section. Peripheral techniques, such as drift compensation, clock extraction, optical signal channel identification, clock phase stabilization, etc., are provided for the implementation of optical multiplexing.

摘要： A method for controlling dispersion in a transmission line includes the steps of: controlling the amount of total dispersion of the transmission in accordance with a control signal; superimposing a low-frequency signal on the control signal; detecting the intensity of a specific frequency component of an optical signal transmitted through the transmission line; extracting a frequency component at the same frequency as the low-frequency signal from the detected specific frequency component; comparing the phase of the extracted frequency component with the phase of the low-frequency signal; and generating, on the basis of the result of the phase comparison, the control signal for controlling the amount of total dispersion.

摘要： An electromagnetic radiation emitter (12) which utilizes a precompensator (14), pulsed light signal, optical fiber cable (18), and a terahertz radiation generator (16). The present invention incorporates an optical precompensator (14) to correct for the stretching of an optical signal as it travels through an optical fiber cable (18). The dispersion characteristics of the precompensator (14) will be equal and opposite to the dispersion characteristics of the optical fiber cable, maintaining the fidelity of optical pulses as they travel through and exit the optical fiber cable (18) striking a device that generates terahertz electromagnetic radiation (16).

摘要： Ein Sender zum Erzeugen eines frequenzmodulierten optischen Digitalsignals weist eine frequenzmodulierbare Lichtquelle und einen optischen Ausgang zum Anschluß eines externen Lichtwellenleiters auf, über den das Digitalsignal übertragbar ist. Zwischen Lichtquelle und optischem Ausgang ist ein optisches Element angeordnet, welches bei der Betriebswellenlänge der Lichtquelle eine chromatische Dispersion aufweist, die ausreicht, das frequenzmodulierte Digitalsignal in ein in detektierbarem Umfang amplitudenmoduliertes Digitalsignal umzuwandeln. Das optische Element kann ein aufgerolltes Lichtwellenleiterstück oder ein Bragg-Gitter sein. Das aufgerollte Wellenleiterstück hat vorzugsweise eine Länge von 3 bis 13 km. Dadurch kann der Sender für Inter-Rack-Kommunikation eingesetzt werden.
