Abstract

The present disclosure is an optical transmission line including: a plurality of multicore optical fiber transmission lines; two input/output devices that are positioned at both ends of the plurality of multicore optical fiber transmission lines, and configured to input light to or output light from a plurality of cores of the multicore optical fiber transmission lines; and a switching connection device that is positioned between the multicore optical fiber transmission lines and the input/output devices, and configured to switch connections of the individual cores of the multicore optical fiber transmission lines to individual cores of a multicore optical fiber of the input/output devices.

Claims (12)

1 . An optical transmission line comprising:

a plurality of multicore optical fiber transmission lines;

two input/output devices that are positioned at both ends of the plurality of multicore optical fiber transmission lines, and configured to input light to or output light from a plurality of cores of the multicore optical fiber transmission lines; and

a switching connection device that is positioned between the multicore optical fiber transmission lines and the input/output devices, and configured to switch connections of the individual cores of the multicore optical fiber transmission lines to individual cores of a multicore optical fiber of the input/output devices.

2 . (canceled)

3 . The optical transmission line according to claim 1 , wherein the switching connection device is configured to switch the connections of the individual cores disposed on a concentric circle of one multicore optical fiber to the individual cores disposed on a concentric circle of another opposite multicore optical fiber by rotation of the one multicore optical fiber on a central axis thereof.

4 . A connection method for

a plurality of multicore optical fiber transmission lines and

two input/output devices that are positioned at both ends of the plurality of multicore optical fiber transmission lines, and configured to input light to or output light from a plurality of cores of the multicore optical fiber transmission lines,

the connection method comprising:

switching connections of the individual cores of the multicore optical fiber transmission lines to individual cores of a multicore optical fiber of the input/output devices, between the multicore optical fiber transmission lines and the input/output devices.

5 . (canceled)
