Abstract

A connection device, capable of visually confirming the connection between a connector pair, including: an optical connector pair that includes a first optical connector and a second optical connector each of which includes a plurality of terminals and corresponding terminals of which are connected to each other by light; a guide light member that guides light to a terminal of one of the first optical connector and the second optical connector; and a visual recognition member that is used to visually recognize the light that passes through from the terminal of the selected optical connector to a terminal of the opposite optical connector.

First claim

What is claimed is:

1. A connection device comprising:
an optical connector pair that includes a first optical connector and a second optical connector each of which includes a plurality of terminals and corresponding terminals of which are connected to each other by light;
a guide light member that guides light to a terminal of the first optical connector; and
a visual recognition member that is used to visually recognize the light that passes through from the terminal of the first optical connector to a corresponding terminal of the second optical connector.

2. The connection device according to claim 1 further comprising:
plurality of optical connector pairs and a plurality of guide light members, wherein
each of the plurality of optical connector pairs includes the first optical connector and the second optical connector, respectively, and each of the plurality of guide light members guides light to the terminal of the first optical connector to the corresponding terminal of the second optical connector in each of the plurality of optical connector pairs.

3. The connection device according to claim 1 , wherein
the guide light member includes a first optical fiber that guides light to the terminal of the first optical connector, from a light source.

4. The connection device according to claim 3 , wherein
the visual recognition member includes a visual recognition window member, and a second optical fiber that guides the light from the corresponding terminal of the second optical connector to the window member.

5. The connection device according to claim 4 , further comprising:
a plurality of optical connector pairs and a plurality of the visual recognition members, wherein
a number of window members and a number of second optical fibers are identical to a number of optical connector pairs, and
each of the second optical fibers guides light from the respective corresponding terminal of the second optical connector to the respective window member.

6. The connection device according to claim 1 further comprising:
a plurality of optical connector pairs each including the first optical connector and the second optical connector, wherein the guide light member forms a light guide that passes through, in order, from the terminal of the first optical connector, to the corresponding terminal of the second optical connector in a certain optical connector pair, to another terminal of another optical connector pair, and the plurality of optical connector pairs are connected to each other in series.

7. A computer system comprising:
a plurality of computer units each of which includes an arithmetic processing device, and a plurality of first optical connectors to which optical signals from the respective arithmetic processing devices are input;
a line arrangement device that includes a plurality of second optical connectors that are respectively connected to the plurality of first optical connectors by light, rearranges signal lines from the second optical connectors and performs output of signals;
a guide light member that guides light to a terminal of a selected one of the first optical connectors or to a terminal of a selected one of the second optical connectors; and
a visual recognition member that is used to visually recognize the light that passes through from the terminal of the selected one of the first optical connectors to a terminal of another one of the second optical connectors, or from the terminal of the selected one of the second optical connectors to a terminal of another one of the first optical connectors.

8. A connection method of a computer system comprising:
performing connection of a plurality of computer units each of which includes an arithmetic processing device and a plurality of first optical connectors to which optical signals from the respective arithmetic processing devices are input, through a line arrangement device that includes a plurality of second optical connectors that are respectively connected to the plurality of the first optical connectors by light, rearranges signal lines from the second optical connectors, and performs output of signals;
guiding light to a terminal of a selected one of the first optical connectors or to a terminal of a selected one of the second optical connectors; and
visually recognizing the light that passes through from the terminal of the selected one of the first optical connectors to a terminal of another one of the second optical connectors, or from the terminal of the selected one of the second optical connectors to a terminal of another one of the first optical connectors, by a visual recognition member.
