至となるため実現されなかつたと考えられる。 Conventional submarine coaxial transmission lines transmit N-channel multiplexed signals from coast station A to coast station B, which is LKm away, by converting them into transmission frequencies f L to f H using frequency division multiplexing. The transmission path is composed of a medium and submarine repeaters inserted every few kilometers to compensate for the attenuation of the multiplexed signals propagating on this cable, and the two coast stations A and B are connected in a straight line. It was connected by a transmission line. Assuming that there are three coast stations A, B, and C as shown in Figure 1, and we are trying to configure a submarine coaxial transmission line connecting the three stations, the coast stations A-B, B-C, and -A
Independent submarine transmission lines 11, 12, and 13 were required between them. This uses the conventional analog multiplex transmission system, and transmits a part of the audio multiplex signal from coast station A to coast station B to coast station C.
This is because a branching device that branches to the coast station C at the intermediate point of the submarine transmission line that connects the two has not been realized.
If you dare to configure a branching device, this device will not be limited to the size of a conventional submarine coaxial repeater.
It is thought that this was not realized because it required something equivalent to a normal analog conversion device and delivery device, and an underwater structure to house them would have been necessary.

せることを目的とするものである。 This invention solves these drawbacks by improving the multi-correspondence line of a single submarine optical cable that accommodates multiple small-diameter optical fibers, the ability to accommodate multiple transmission systems with different transmission speeds, and the ability to accommodate internal units of submarine optical repeaters. Focusing on distributed configuration technology, the aim is to use this technology to provide branching and adding functions to submarine optical fiber cable transmission lines without changing the size of ordinary submarine optical repeaters. .

る利点等がある。 As explained above, the submarine transmission line between the three coast stations A, B, and C or between the four stations A, B, C, and D has a branching/adding function at the submarine optical repeater or cable connection box 14. By doing so, the transmission path can be easily branched. Also, between coast stations A and B there is a small capacity transmission line, between coast stations A and C,
A large-capacity transmission line may be used between C and B. In the conventional submarine coaxial transmission system, as shown in Figure 1, when configuring a transmission line between coast stations A, B, and C, submarine coaxial cables are connected to coast stations A-B, B-C, and C-A, respectively. However, this invention is economically advantageous. After installing a submarine optical transmission line, for example between coast stations A and B, by equipping the submarine optical repeater or cable connection box 14 with branching and insertion functions in advance,
There is an advantage that a transmission line can be laid from any submarine optical repeater or cable connection box 14 to the coast station C as required.
