Method of manufacturing optical transceiver and adjustment device thereof

A method of manufacturing an optical transceiver, comprising:

• combining an optical socket and an assembling object to be assembled with the optical socket, the optical socket including a fitting hole to mount an optical plug holding an end portion of an optical fiber;
• mounting an optical head to photograph the assembling object in the fitting hole of the optical socket and to obtain an image of the assembling object exposed to the fitting hole and reference position information in a photographed image display screen;
• detecting a difference between the image of the assembling object and the reference position information;
• reducing the difference by moving the optical socket and the assembling object relative to each other based on the difference;
• fixing the assembling object and the optical socket;
• and
• including at least one of a wiring pattern, a positioning mark, a positioning hole, a light-emitting element, a light receiving element, a lens, and a window of the can package which are formed on the assembling object.
