Optical connector.

摘要

An optical connector in which the deformation of the connector caused by the shrinkage of an adhesive at the time of adhering and fixing an optical fiber and a ferrule is small, and the increment of loss in connection is suppressed. The optical connector in which different adhesives (A and B) are used in an optical fiber insertion hole (2) portion and an adhesive injection opening portion (4) respectively. (1) Adhesives different in Young's modulus are used for an optical fiber insertion hole portion (2) and an adhesive injection opening (4) portion respectively. (2) Adhesives different in linear expansion coefficient are used for the optical fiber insertion hole portion (2) and the adhesive injection opening (4) portion respectively. (3) A thermosetting adhesive is used for the optical fiber insertion hole portion (2) and an ordinary-temperature-setting adhesive is used for the adhesive injection opening portion (4) respectively. (4) Adhesives different in coefficient of hardening shrinkage is used for the optical fiber insertion hole portion (2) and the adhesive injection opening portion (4) respectively.
