Abstract

An optical cross-connect component mutually connecting an end of a first optical fiber group and an end of a second optical fiber group is disclosed. The optical cross-connect component includes a plurality of first connectors housing therein the end of the first optical fiber group, and a plurality of second connectors housing therein the end of the second optical fiber group. The m×n optical fibers in the first optical fiber group are housed in any of the plurality of first connectors, and the m×n optical fibers in the second optical fiber group are housed in any of the plurality of second connectors. The end of the first optical fiber group and the end of the second optical fiber group are connected so as to be butted to each other.

First claim

What is claimed is:

1. An optical cross-connect component mutually connecting an end of a first optical fiber group and an end of a second optical fiber group, each of the first and second optical fiber groups having m×n optical fibers arranged in a matrix of m rows×n columns at the ends, wherein in and n each represents an integer equal to or more than two, the optical cross-connect component comprising:
a plurality of first connectors housing therein the end of the first optical fiber group, each of the first connectors having at least n holes configured to respectively hold the optical fibers of the first optical fiber group therein; and
a plurality of second connectors housing therein the end of the second optical fiber group, each of the second connectors having at least m holes configured to respectively hold the optical fibers of the second optical fiber group therein,
wherein the m×n optical fibers in the first optical fiber group are housed in any of the plurality of first connectors, and one first connector of the plurality of first connectors collectively houses therein n optical fibers arranged in at least, any one row of the m rows,
wherein the m×n optical fibers in the second optical fiber group are housed in any of the plurality of second connectors, and one second connector of the plurality of second connectors collectively houses therein m optical fibers arranged in at least any one column of the n columns, and
wherein the end of the first optical fiber group and the end of the second optical fiber group are connected so as to be butted to each other.

2. The optical cross-connect component according to claim 1 ,
wherein the plurality of first connectors are in first connectors, each first connector collectively housing therein the n optical fibers arranged in each row at the end of the first optical fiber group, and
wherein the plurality of second connector are n second connectors, each second connector collectively housing therein the in optical fibers arranged in each column at the end of the second optical fiber group.

3. The optical cross-connect component according to claim 1 , further comprising:
an adapter fixing at least one first connector of the plurality of first connectors and fixing at least one second connector of the plurality of second connectors.

4. The optical cross-connect component according to claim 3 ,
wherein the adapter comprises a frame including one end face and other end face opposite to the one end face, and
wherein the frame comprise at least one guide hole on the one end flee, for being connected to the first connector via a guide pin and at least one guide hole on the other end face for being connecting to the second connector via a guide pin.

5. The optical cross-connect component according to claim 1 ,
wherein the two first connectors positioned on both ends in a column direction respectively have a guide hole for being connected with at least one second connector of the plurality of second connectors via a guide pin, and
wherein the two second connectors positioned on both ends in a row direction respectively have a guide hole for being connected with at least one first connector of the plurality of first connectors via a guide pin.

6. The optical cross-connect component according to claim 2 ,
wherein the two first connectors positioned on both ends in a column direction respectively have it guide holes for being connected with the n second connectors via guide pins, and
wherein the two second connectors positioned on both ends in a row direction respectively have m guide holes for being connected with the m first connectors via guide pins.

7. The optical cross-connect component according to claim 1 ,
wherein the end of the first optical fiber group and the end of the second optical fiber group are butted to each other via a refractive index matching material.
