Abstract
An optical module includes a photoelectric element that performs a conversion between an optical signal and an electric signal; a body having a first surface and a second surface, the first surface and the second surface being continued and adjacent to each other; and an electric circuit board that is mounted on the body, the electric circuit board having a bending portion that is bent along the first surface and the second surface. The photoelectric element is mounted on one portion arranged on the first surface bordering on the bending portion. An electric wiring board on which a wiring unit for an external connection is formed is mounted on other portion arranged on the second surface.
Claims19
An optical module comprising:
- a case having a substantially rectangular shape with a side wall and an open side adjacent to the side wall;
- a flexible member that is mounted on the case and has a first portion along the side wall and a second portion along the open side;
- a photoelectric element that is mounted on the first portion so that the flexible member is sandwiched between the photoelectric element and the case;
- an optical fiber that is housed in the case;
- and
- an electric circuit that is housed in the case and is located in a space between the optical fiber and the second portion of the flexible member, and is electrically connected to the photoelectric element through the flexible member.
An optical module having a circuit board, photoelectric element electrically connected and an optical fiber, comprising:
- a case inside which is mounted the circuit board and the optical fiber, having a substantially rectangular shape with at least one open side adjacent to a side wall;
- and
- a flexible member mounted on the case, having a first portion along the side wall and a second portion along the open side, wherein
- the first portion of the flexible member is sandwiched between the photoelectric element and the case, and
- the circuit board is located in a space between the optical fiber and the second portion of the flexible member, and is connected to the photoelectric element through the flexible member.
A light emitting module, comprising:
- a case with an open side;
- a flexible circuit board that is mounted outside the case, along the open side and along a side wall adjacent to the open side;
- an optical unit having at least one light emitting element, the optical unit being mounted on the flexible circuit board in an outward direction from the side wall;
- an optical fiber to transmit light received from the at least one light emitting element through at least one pair of corresponding holes in the case and the flexible circuit board, respectively, the optical fiber crossing the case;
- and
- an electric circuit that is housed in the case on a side of the flexible circuit board that covers the open side of the case, and is electrically connected to the at least one light emitting element through the flexible circuit board.
