OPTICAL FIBER SOCKET

摘要

Disclosed is an optical fiber socket and an assembly method for the same, said optical fiber socket enabling high accuracy optical coupling of optical fibers without actually connecting the optical fibers and without using a measurement device. A lens block bearer (4) and a lens block (5) are formed to an accuracy (first accuracy) with a dimensional error of 1µm or less using lens formation technology. The lens block bearer (4) is mounted on a first mounting surface (21) of a circuit substrate (2), and a light receiving element or a light emitting element (3) is further mounted on the first mounting surface (21) to an accuracy (second accuracy) of, for example, approximately 10µm with respect to fitting holes or fitting projections used for the positioning of the lens block cradle (4). Furthermore, the lens block bearer (4) and the lens block (5) are fitted and fixed. Thus, an optical fiber (10) can be optically coupled (optical axis alignment) to the light receiving element or light emitting element (3) to an accuracy of approximately 10µm.
