Abstract: An optical apparatus includes a package, a board, a plurality of first optical cables, and a first optical connector. The package includes an integrated circuit and an optical device that converts an electrical signal from the integrated circuit into an optical signal. The board includes a main surface, and the package is disposed on the main surface. Each of the plurality of first optical cables includes a plurality of optical fibers. Each of the plurality of first optical cables includes a first end portion and a second end portion on a side opposite thereto. Each of a plurality of the first end portions is optically coupled to the optical device, and each of a plurality of the second end portions is attached to the first optical connector. The first optical connector is disposed on the main surface of the board to be entirely located inside an edge of the board.

Abstract: An optical connector jig for connecting a second optical connector to a first optical connector, or disconnecting the second optical connector from the first optical connector, includes a first housing and a second housing. The first housing includes a positioning portion to determine a position of the jig with respect to the first optical connector in cooperation with a member indicating a position of the first optical connector. The second housing grips the second optical connector such that, when the jig is positioned with respect to the first optical connector, a connection surface of the second optical connector faces a connection surface of the first optical connector. The second housing moves with respect to the first housing such that the connection surface of the gripped second optical connector is close to or away from the connection surface of the first optical connector.

Abstract: A circuit board with an optical path conversion component includes a circuit board having a main surface, an optical path conversion component connected to the circuit board, and one or more first fiber ribbons. Each of the one or more first fiber ribbons has a first end and a second end, and includes a plurality of optical fibers optically coupled to the conversion component at the first end. The one or more first fiber ribbons extend in a direction crossing a normal of the main surface. The conversion component has at least one channel group for each of the one or more first fiber ribbons, the at least one channel group including a plurality of channels optically coupled respectively to the plurality of optical fibers. The plurality of channels are arranged in a direction crossing the main surface for each of the at least one channel group.
