摘要： A feed line switching circuit includes a relay connected between feed lines, a normally close contact of the relay, and a resistor that constitutes a series circuit with the normally close contact, which series circuit is connected in parallel with the relay. The resistance of the coil of the relay and the resistance of the resistor are determined to satisfy the condition that the current flowing through the relay after energizing the relay can prevent the chattering of the relay. Thus, the feed line switching circuit can positively carry out the feed line switching.

摘要： A plurality of submarine cable transmission paths extending from a plurality of land-based terminal stations are connected with each other in a submarine branching apparatus, and an electric power feeding line is arranged between each land-based terminal station and an electric power feeding line switching unit of the submarine branching apparatus to supply electric power from the electric power feeding line to a communication signal of the corresponding submarine cable transmission path through repeaters. The electric power feeding lines are connected with each other in the electric power feeding line switching unit. A control signal superposed on the communication signal is sent to the electric power feeding line switching unit through one submarine cable transmission path, and the connection of the electric power feeding lines is switched according to the control signal. Because the switching is performed when the electric power feeding lines are electrically set to a stable state, no electric arc is generated in the switching. Also, each submarine cable transmission path is formed of an optical fiber, so that the electric power is supplied from one electric power feeding line to the control signal of the submarine cable transmission path. Therefore, the control signal is not attenuated, and the connection of the electric power feeding lines can be reliably switched.
摘要翻译：从多个陆基终端站延伸的多条海底电缆传输路径在海底分支装置中相互连接，并且在每个陆基终端站和馈电线路切换之间设置馈电线路将从供电线路供给电力的海底分支装置的单元设置成通过中继器对应的海底电缆传输路径的通信信号。供电线在供电线切换单元中相互连接。叠加在通信信号上的控制信号通过一条海底电缆传输路径发送到馈电线路切换单元，并且根据控制信号切换馈电线路的连接。由于在将供电线电气设定为稳定状态时进行切换，所以在切换中不产生电弧。此外，每个海底电缆传输路径由光纤形成，使得电力从一个馈电线路供应到海底电缆传输路径的控制信号。因此，控制信号不衰减，能够可靠地切换供电线的连接。

摘要： An optical-fiber light amplifier using rare-earth-doped optical fibers. The light amplifier combines first and second excitation light from first and second sources to form combined excitation light and divides the combined excitation light for inverted distribution to both two optical fibers. The light entered one optical fiber and that entered the other optical fiber are polarized so as to be perpendicular to each other so that fluctuation of output level is prevented without mutual interference. Alternatively the first excitation light and the second excitation light may have different wavelengths; also in this case, fluctuation of level is prevented without any interference.
