摘要： An optical transmission system accomplishes optical transmission to a long distance by combining a multiplexing line terminal with optical amplifiers, linear repeaters, and regenerators with optical amplifiers combined together. The system also accomplishes the optical transmission to a short distance by directly connecting the linear terminals therebetween, with an electric-to-optic converter replaced by an electric-to-optic converter having a semiconductor amplifier, with an optic-toelectric converter by an optic-to-electric converter having an avalanche photodiode as light receiver, an with no use of any optical booster amplifier and optical preamplifier in the multiplexing line terminal. With these, the optical transmission system can be easily constructed depending on the transmission distance required.

摘要： A clock extractor is disclosed in which an input data signal is sampled and held in accordance with a sampling frequency, the input data signal thus processed is subjected to equalization and amplification, a difference in voltage (namely, height) is detected between those portions of a waveform obtained after the equalization and amplification which appear before and after a time when the waveform has a maximum voltage amplitude, a phase of that portion of the waveform which has the maximum voltage amplitude, is determined by making the above-mentioned difference equal to zero, and a clock signal synchronized with the portion having the maximum voltage amplitude is extracted and reproduced from the input data signal.
