摘要： In an optical fiber connector, the pair of optical fibers to be connected together are placed end-to-end in a linear groove which has been formed on a lateral surface of a central cylinder. They are held fixed by a holding member which is fitted in the groove and is moved towards the optical fibers according to the rotation of a hollow cylinder which externally touches the central cylinder, whereby the optical fibers can be connected with a precise alignment and accordingly with a low optical power loss.

摘要： In order to enhance the general purposeness of a time domain multiplexer for digital channel signals of unequal bit rates, the time domain multiplexer is constructed of a plurality of channel units which provide information signals and bit rate signals of input channel signals, a plurality of logic circuits which multiplex the information signals from the channel units, and a control circuit which selects and combines the logic circuits in accordance with the bit rate signal so as to construct a multiplexer conforming with the bit rate.

摘要： A two-level alternate mark inversion signal transmission system wherein binary pulses of "1" and "0" levels are converted into a pulse signal in which one coded information value has its polarity inverted at a period T and the other has its polarity reversed at a period T/2, and the converted signal is transmitted. In order to facilitate an automatic gain control operation and the proper and reliable extraction of a timing signal on the receiving side of the system even when the zero binary pulses have successively arisen in the signal processed on the transmitting side, the alternate mark inversion signal is converted into a specified code (zero substitution) signal when the zero binary pulses have succeeded one another for a predetermined number of times, while on the receiving side, a received signal is subjected to duobinary shaping, whereupon the zero substitution part is detected for removal by utilizing the rules of the zero substitution process and the alternate mark inversion signal.
