Patent ID: 7430375

Claim:
An optical transceiver including: a light emitting element which converts an electric signal into an optical signal; a light receiving element which converts the optical signal into an electric signal thereby enabling a single-wire two-way communication by using an optical fiber; an optical integrated chip in which said light emitting element and said light receiving element are integrally formed, a light emitting section of said light emitting element and a light receiving section of said light receiving element are coplanar on a surface of said optical integrated chip, and said light receiving section surrounds said light emitting section; and a circuit board having a via hole for inserting said optical fiber, wherein, said optical integrated chip is mounted on one surface of said circuit board at a position where said light emitting section and said light receiving section are fitted into said via hole, said optical fiber extends though said via hole from the other surface of said circuit board to a position where an end surface of said optical fiber is brought into contact with said optical integrated chip, and said light emitting section and said light receiving section are placed at a distance such that a part of each section is in contact with a diameter portion of a transversal cross-section of a core of said optical fiber.
