摘要： An optical fiber submarine cable, which is provided with at least one coated optical fiber, a power supplying, pressure resisting layer of a pipe-like configuration, a tension resisting wire layer formed of a conductive material of relatively low conductivity and disposed in close contact with the power supplying, pressure resisting layer of the pipe-like configuration, and an insulator layer disposed around the tension resisting wire layer. The power supplying, pressure resisting layer is formed as at least one inner layer and an outer layer. The inner layer is formed as a single layer or composite layers by forming a tape-like good conductor material into a pipe-like configuration with its joint made a mere butt, or by assembling together a plurality of pressure resisting material segments equally divided in the circumference direction for at least one layer of the inner layer and having housed the above-mentioned at least one coated optical fiber in an optical fiber housing space defined centrally of the inner layer. The outer layer is formed by winding a metal tape on the inner layer.

摘要： The error rate and the operation of repeaters inserted in an optical transmission line are monitored at the terminal station on land by transmitting the test signal and monitoring the response signal of repeaters through the optical data transmission line without utilizing interstitial copper pair. Each repeater has the particular identification code, and the transmission terminal transmits the test code having the repeater identification code and an acknowledgement block with an empty bit position on the time divisional basis with the data to be transmitted. The repeater which finds his identification code in the test code, inserts the response in the acknowledgement block, and repeats the signal including both said test code and the data to be transmitted. The reception terminal analyzes the response signal of each repeater to determine the error rate of each repeaters.

摘要： The operation of a laser in an optical repeater in an optical transmission system using an optical fiber cable is telemonitored at a terminal station by changing the mark ratio of the test signal which is transmitted from the terminal station to the circuit. Each of the repeaters has an optical-electrical conversion element for the conversion of the input optical energy to electrical energy, an amplifier for amplifying the electrical output of said conversion element, a laser for converting the electrical output of the amplifier to an optical output power, a device for controlling the optical output power of the laser, a switch for providing the signal return path between the upward circuit and the downward circuit, and a monitoring circuit having a reference voltage generator for providing a reference lever which is lower than the normal signal level when the signal has the mark ratio of 1/2, and a comparator for comparing the laser output with the reference level, and a device for turning OFF the switch when the monitoring circuit provides the output signal indicating that the laser output is equal to the reference level. The terminal station designates the particular repeater and closes the switch of the designated repeater, then, transmits the test signal having the controlled mark ratio. That test signal returns to the terminal station reflected by that closed switch. By adjusting the mark ratio of the test signal, the monitoring circuit of the repeater provides the output when the laser output equals to the reference level, and has the switch turned OFF. Thus, the terminal station recognizes the degree of the degration of the laser from the mark ratio when the circuit is broken.

摘要： A light dispersion measuring apparatus, provided with a light source for generating reference light pulses of short duration and of a constant frequency and also variable-frequency light pulses in synchronization with the reference light pulses but at a frequency different therefrom. A variable optical delay line delays the reference light pulses. An optical transmission medium, to be detected and to which the variable-frequency light pulses are applied is provided. An optical non-linear effect element receiver the output light pulses from the variable optical delay line and the optical transmission medium and is disposed so that when the two light pulses coincide emitted from the light source with each other, the sum component of the frequencies of the two types of light pulses produces a maximum output. A photo detector detects the sum component. Light dispersion in the optical transmission medium being measured from the delay of the variable optical delay line is adjusted so that the sum components yields a maximum output with respect to the frequency of the variable-frequency light pulses. The frequency of the reference light pulses can be made to be equal to the variable-frequency of the variable-frequency light pulses.
