は反対側から来たケーブル結合器と接続するかしないと
システム給電ができないので、こういった場合以外には
システム試験ができないという問題点があった。In the conventional submarine cable, when only the cable coupler is placed on the seabed, the power supply line in the cable is sealed in a pressure-resistant container and is insulated from seawater. Since the system power cannot be supplied unless the coupler is lifted on the ship or connected to a cable coupler coming from the opposite side, there is a problem that the system test cannot be performed except in such a case.

局舎の受信装置で受信して行う。In this embodiment, the power supply line 2 from the cable coupler 1 is connected to the pressure-resistant container 3 through the hermetic terminal 4.
From the outside and connected to the ground electrode 5 provided outside the pressure-resistant container 3, the power supply line 2 of the submarine cable 6 can have the same potential as the potential of seawater. FIG. 2 shows an example of the usage status of the submarine ground electrode of the present embodiment.
A power supply loop is provided from the power supply device of the land station to the observation device 11 via the cable (metal cable or optical cable) 12, and returns from the submarine ground electrode 10 at the tip to the earth 13 on the land side with the ground as a return path. To use. When a system test is performed in such a configuration, the observation device 11 is operated in a state where power is supplied from the power supply device in the station building.
Observation data transmitted from the satellite via the cable 12 is received by the receiving device at the land station.
