Abstract
An optical module that has a structure ensuring reduction in size. The optical module has a structure where a part of a fiber block is protruded from a housing. By including a thin plate, this optical module can avoid entering of dust in the housing, allows a position shift of the fiber block due to a mounting position error of an optical component in the housing, a position shift of an opening portion due to a dimensional error of the housing, or a displacement due to a temperature change, and can reduce the coupling loss due to the optical axis misalignment.
