1. An optical wiring comprising:
a plurality of first set groups each including a plurality of first connecting components which are each mounted with an optical fiber and which are arranged in a row;
a plurality of second set groups each including a plurality of second connecting components which are each mounted with an optical fiber and which are arranged in a row; and
a receptacle which has a first end face and a second end face on an opposite side of the first end face and in which the plurality of first set groups are connected to the first end face side and the plurality of second set groups are connected to the second end face side, wherein:
the plurality of first set groups faces the plurality of second set groups through the receptacle such that a direction in which the first connecting components are arranged and a direction in which the second connecting components are arranged are perpendicular to each other, and each of the plurality of first connecting components is optically connected to a corresponding one of the plurality of second connecting components in the receptacle,
the plurality of second connecting components include a second connecting component for optical transmission mounted with an optical fiber that transmits an optical signal travelling from one of the plurality of second connecting components to one of the plurality of first connecting components, and a second connecting component for optical reception mounted with an optical fiber that transmits an optical signal travelling from one of the plurality of first connecting components to one of the plurality of second connecting components, and
each of the plurality of second set groups includes only one of the second connecting component for optical transmission or the second connecting component for optical reception.
